Comments to the author.
Introduction
Only a bare bones introduction here so far.
Summary
This document outlines my current vision for a second revision of the Green Map
symbols, as I would have it were I a benevolent dictator. The icons were
recategorized (except these) in in an attempt to simplify
the scheme, helping to clarify and reduce redundancy.
TODO: Create a summary of "Such and such icons were deleted/added/modified."
as a table with icons crossed/highlighted, etc?
For reference here are the version 2 definitions (local copy).
Purpose
icon vs. symbol. SAX
Too much has been crammed into the single dimension of unique pictorial point
symbols. There's also size, color, texture, linear and polygonal features, etc.
AND the text accompanying the map.
Process
In developing this recommendation for the next set of Green Map symbols a
variety of inputs were considered including a survey of icon usage in
60 maps,
known local icons,
various map-makers' comments, and observations of some maps' recategorization
of icons as well as some of the ideas presented in
Improving the Cartographic Quality and Design of Greenmaps
Local icons are seen as generally being symptomatic of one of three things:
1) a misunderstanding of the base set of symbols 2) a problem with the base
set e.g.; a gap in coverage 3) a map-maker veering of the beaten path.
None of these things should be seen as exceptionally negative. Problems of
language or hidden assumptions could easily give rise to the first case, and
both the first and second are to be expected in an evolving, and as yet, young
system.
In order to maintain universal readability local icons should be avoided
when a base icon is available to convey the same or very similar type of
feature. Creative recasting of an existing icon is always preferred to use of
foreign symbols. Substitution of a green map icon with a pre-existing icon in
common use for the feature type is acceptable, though still discouraged.
For instance, you might use the logo for the local transit system instead of
the "Major Public Transportation Station". If you do use a substitute for a
base set icon, it is recommended that both the susbtitute and base set icon be
included in the map legend to increase readability.
There were a few miscellaneous concepts which also played in the evaluation.
- To only use apples in the context of food.
- To have a minimum of symbol categories.

Usage data
Usage data includes the number of maps using each symbol in Total, Misused,
Redefined, and Missing categories. The results are from a survey of of 60 maps,
and largely based upon legends given an absence of knowledge of ground
conditions. For example
31 used : 4 misused : 1 redefined : 5 missing
Where the lables are defined as:
- Misused
- The symbol was not used in the way described in the
GMS v2 Icon Definitions
(local copy).
- Redefined
- The symbols's definition was creatively redefined to something very similar.
- Missing
- The symbol could have been used but was not.
Note: Redefined and Missing are particularly difficult to judge and may be undercounted.
7 used
where unusual or typical forms are apparent. May be exposed rock
layers, glacial till or a chasm view. You could discuss how feature was
formed. Could be a layer on a GIS map.
4 used : 1 misused : 0 redefined : 1 missing
notable wildlife habitat or natural area which may be rare or especially
beautiful and rich. May have resources, for example, for turning your
lawn back into a prairie, or for encouraging native animals to flourish.
Map should Include details on the sensitivity of the areas.
Icon: v2 Bioregional icon?
7 used : 0 misused : 0 redefined : 2 missing
shows the topography or waterways of the larger region. Includes
plants native to the bio-region. Text can discuss bio-regional boundaries
within or near the Green Map. Could be a layer on a GIS map or the whole
Green Map could be based on bio-regional boundaries instead of political
limits.
Merged into Significant habitat.
23 used : 1 misused : 1 redefined : 1 missing
site that is publicly owned and accessible to all. A wide variety of natural
areas can use this symbol. Balance your emphasis of forests with parklands to
discourage the over-use of natural areas.
Erosion due to poor land or water management including farming practices
and deforestation.
Icon: A crumbling cliff?
Alas, this should be all to obvious.
Icon: An axe, or better yet an axe stuck in a tree stump
Replanting a damaged or absent forest, erosion control, etc.
Icon: A 2 or 3-leafed sprout, sort of like
though I'd prefer a stem with a pair of leaves at the base (one on each side)
and a single leaf to one side at the top
2 used : 1 misused?
bamboo of any variety, a forest of any size. A fast growing renewable
resource of major benefit.
This icon has been removed; it was deemed too specific and of narrow interest/
applicability, particularly given the existence of the more generally useful
Public Forest/Natural Area and Significant Habitat symbols. You may also be
interested in the Alternative Fibers symbol below, which could easily be used
in combination with the Public Forest/Natural Area or Significant Habitat
symbols
Renewable (fast growing) fiber sources. From dead tree alternatives such as
bamboo, jute, and hemp to organic cotton or sustainably managed forests/
silviculture plantations (tree farms).
Icon: "v2 Bamboo Forest" icon
Green- Corridors, Belts and Ways (Wildlife Corridor / Greenways):
7 used : 0 misused : 1 redefined
Greenways often follow river or stream beds, ravines or steep hills, and
are left in a natural state (more or less). May also be used to indicate a
corridor dedicated to safe wildlife passage, or greenbelts (tracts of land
set-off limits to deter/confine sprawl).
Wild Foodstuffs (Gleaning Area / Fishing):
9 used : 1 misused
Gather wild food here, including mushrooms, seaweed, greens, berries and
other fruits. Note: Publicizing resources may increase pressure upon them,
advise readers to practice moderation to prevent over-harvesting.
Icon: Similar to the existing icon, but add 1 or 2 loops/handles to more clearly represent `basket'
!!! Farms that permit gleaning or services that pick up party leftovers for food banks.
4 used
a full-size organic farm or small-scale city farm, includes
perma-culture, and free-range livestock. Can be used to
indicate organizations that make the link between urban communities and
nearby farmers through community-supported agriculture--also known as box
schemes--and agri-schools or food security resources such as food banks.
22 used : 2 misused : 1 redefined
Botanical garden, native wildflower society, arboretum, etc.
22 used : 1 misused
often on public or formerly abandoned land, Places where people plant
and grow their own vegetables and flowers in small plots. People also
grow relationships and a close connection to the city. Sometimes fenced
and locked; sometimes threatened by development. Include contact information.
Icon: Perhaps or 
but I strongly recommend using the
v2 "Special Garden" icon as it best captures the concept.
10 used : 0 misused : 0 redefined : 2 missing
especially nice. Along with a diversity of plants, may have a
stage, artwork, solar powered water features, nice seating or other amenities.
Publicly accessible and cooperatively run. This Icon can be used to indicate
a special garden that, though private, can be easily seen by pedestrians.
Merged into "Community Garden"
Incorporation of as many of the following or similar concepts as possible:
xeriscaping (drough tolerant design), native plants, bat boxes, birdhouses,
butterfly gardens, amphibian habitat
Icon: v2 "Significant Habitat" icon
7 used : 0 misused : 0 redefined : 1 missing
open, natural area within an urban area or in the developed countryside.
This is an ill-defined category that overlaps others. If a clearer, distinct,
defintion can be created a more intuitve icon than `infinity' is needed.
23 used : 1 misused : 1 redefined : 1 missing
green space that offers place to relax and play. May include sports
fields, running paths, canoe rental, or children's play equipment, along
with vegetation and a pond, creek or other water feature. Some parklands
may be publicly-owned and free; others might charge admission.
Parkway (Shaded Boulevard):
7 used : 0 misused : 0 redefined : 1 missing
are designed to be pleasant for walking and bicycle riding in hot climates.
!!
11 used : 0 misused : 1 redefined
A traditional urban gathering place, public open space which may have
benches, fountain, etc. Occasionally a public square is located in a garden
or park, or indoors in a mall.
6 used : 0 misused : 1 redefined
exciting design features including public transport stations,
plazas, integrated native plantings and street furniture such as kiosks,
benches, fountains, or lighting that use materials and energy efficiently,
contributing to the streetscape. Can indicate an area planned for ecological
soundness.
Merged with Green Building
0 used
a source for the best materials and supplies for sustainable building,
landscape, graphic, product, fashion and other kinds of design. May be
an organization for information, or a place to gather natural materials,
a store, exchange center or showroom. Simply may be a place where you
can draw inspiration from natural systems.
Unfocused and unused, this largely duplicates aspects of other symbols.
Icon: v2 "Eco Design/Planning Feature" if kept
13 used : 2 misused : 1 redefined
Buildings made with responsible materials and building systems,
or projects incorporating any of various design philosphies including mixed
use, New Urbanism or co-housing, and often give offer
public tours emphasizing how to reduce negative impacts. May include centers
for energy efficiency and understanding environmental systems for buildings.
Icon: The icon is okay, especially if the e theme were carried
through to other symbols where appropriate, otherwise the building with a
gridded-globe cut-out might also work.
1 used : 1 misused
Can represent shanty towns or favelas that form in urban areas to
house low-income people, or earth-built homes of natural materias such
as adobe or straw. This homemade housing often reuses building materials.
See also "Environmental Justice" and "Green Building"
Poor urban planning consumes virgin land (greenfields) in city expansion,
often at the expense of mobility/commute time in addition to wildlife habitat.
Icon: Some sort of expanding city edge?
7 used
Prior industrial site (brownfield), which may have been contaminated,
has been cleaned up and is ready for natural systems to take over, or to be
re-developed. In the US, brownfields (land either contaminated by toxics, or
perceived to be) programs are putting remediated industrial lands back to
work, often in areas where people need jobs. Can include sites where the
cleanup is in progress.
5 used : 2 misused : 0 redefined : 1 missing
area that is well-located for ecologically-sound regeneration. Might
currently be a blight site, paved over or even in use, but has the potential
to be a wonderful addition to the community and environment.
7 used : 1 misused
Generally, conventional fossil-fueled facilities that provide
electricity to the public. You may also include hydro-electric or nuclear,
depending upon your feelings regarding them, with this icon.
Otherwise see Geothermal, Nuclear Facilities and Waste, Hydro Power,
Solar Power, and Wind Power symbols.
Heat pumps, hot water systems, electricity generation.
Icon: Geyser?
0 used
possible source of radiation leaks and radioactive wastes. May be
destination points for trucks and trains carrying radioactive materials;
military, health and research facilities.It might be of interest to note
the percentage of electricity that comes from nuclear power plants in
your area.
Fossil Fuel Facility (Oil and Natural Gas Facility):
4 used : 1 misused
Can be a "tank farm" with several large storage containers,
or a place where oil is pumped and processed. Where does the energy that
powers your lifestyle come from? What are the hazards associated with
current practices?
4 used : 0 misused: 0 redefined : 2 missing
Current or prior mine OR QUARRY; you may wish to indicate what
kind was extracted.
Some cities or structures are built directly on top of mines and quarries.
Mines are notorious hotspots.
6 used
Sources of potential soil and ground water contamination;
usually used for oil and gas leaks; for example, a gas station with
leaking underground tanks can be an invisible source of pollution. Home
fuel oil storage tanks can also be a problem source.
8 used
municipal solid waste dump where garbage and soil are layered together,
sometimes in a properly lined landfill (dump) facility with a
methane gas capturing system. When filled, decommissioned landfills are
capped and sometimes landscaped.
(Officially Listed) Contaminated Site:
5 used
site on the government's official priority "clean-up" list, where
applicable, like the USEPA's Superfund list. Can be used for
other severely polluted sites, even in countries without an official
list. In some countries, these sites must be cleaned up by industry.
13 used
An area generally destroyed with toxics and other ugliness
by uncaring industry and people. Set and state your criteria.
4 used : 1 misused
where motorized traffic is especially heavy, noisy, polluting and dangerous
to pedestrians, bicyclers and nearby residents.
Merged into "Danger Zone"; it is a natural subset of "Danger Zone" and the icon
caused problems for some.
2 used
A dangerous area including natural phenomena or man-made hazards
such as volcanoes and high-crime areas or animal crossings.
Any kind: big or small hydroelectric, run-of-river, or tidal.
Icon: Waterwheel
11 used
for human powered boats such as canoes, rowboats or kayaks,
or wind powered ones like sailboats. Your map can mention if a permit
is needed, or if there are other restrictions.
18 used : 3 misused : 1 redefined : 1 missing
place where you can watch, walk along and play by the water. Water bodies of
all types. Swimming and wading may be possible.
9 used : 1 misused
may be on the official protection list. These areas are important habitats
and useful for water cleaning. May be natural, reconstructed or artificial.
You may include guidelines for viewing sites, which may be on private
land.
12 used : 0 misused : 0 redefined : 2 missing!!
could be a beautiful fountain, waterfall or natural pond. May simply
celebrate water or offer a refreshing drink. May be ecologically
designed. e.g; springs, hot springs, water plazas
5 used
place where ducks, geese, and other waterfowl gather. In cities, often a
good place to watch and feed the birds. In the wild, just enjoy their water
ballet.
7 used
using plants and aquatic animals to aerate, filter and purify
water without adding chemicals, alternative storm water management.
There are many kinds of high and low tech water recycling systems in the
built environment. e.g; grey water, cisterns, green roofs
Icon: Recycle symbol with a drop of water inside the arrows?
7 used : 0 misused : 0 redefined : 2 missing
may include a specific factory's pollution stream or an inadequate
sewage treatment plant. Sometimes, these are "non-point" sources, like
where pollutants wash off paved roads or a farm where animal wastes and/or
chemical fertilizers drain off the land into drinking water supplies.
e.g; golf courses
Icon: Curent icon is too similar to "Toxic Release", use `Cuba''s?
11 used : 2 misused
indicates the source for your drinking water.
May be used to show reservoirs, and major elements of the water system.
Water purity and conservation information. Icon can be used in a line
to indicate major underground pipelines.
Icon: Clarify by using a drop of water coming out of a faucet, like
several projects including `France' and `Cuba'? On the other hand the
"Drinking Water Source" / "Wastewater Treatment Facility" pairing is good.
11 used
generally, municipal systems for treating wastewater and sewage,
some with public information centers or tours.
Money & Material Flows
27 used : 2.5 misused : 1.5 redefined
You can create strict criteria like the ones in Oakland, California,
or use a softer approach to selecting businesses that practice "green"
policies. Or, you can leave them off and let the community discussion
help determine what to include in the next edition.
Icon: Perhaps a leaf with the universal (or local) currency symbol superimposed on it?
Member owned grocery store, vegeterian housing cooperative, locally owned
business--this is generally only worth indicating if it's "abnormal" for this
kind of thing to be locally owned e.g; community credit unions
Icon: V2 "Green Business/Service" icon
Repair, preferably green repair i.e; of bicycles or refrubishing of
appliances. You may want to stress balancing reuse/embedded energy vs.
the continued use of a potentially inefficient product
Icon: A wrench
18 used : 1 misused
has only ecologically-conscious products. Now, you may not agree that
100% of them are truly a big improvement, but the intention, method of
production, materials, reductions of impacts in use, store policies and
so on, are all going in the right direction.
This is really just a matter of degree of "Green/Conserving Products",
so use that symbol and add empahsis with color or increasing it's size, etc.
15 used : 1 misused : 3 redefined
A store likely to carry a few which carries many eco-products
among many that are conventional. In Calgary, Green Product selection was
based on the following criteria: necessity of product, safety, quality, made
from renewable or recycled materials, responsible packaging, information on
manufacturing practices, options for disposal, whether locally produced and
consideration of overall business practices.
Icon: Replace with something more identifiable than a Compact Fluorescent
Lightbulb, perhaps the Energy Star or Blue Angel?
15 used : 1 misused : 2 redefined : 1 missing
this "light green" category includes somewhat green and socially
responsible products and policies, but doesn't offer many things that
"go all the way". Look closely at the shop's products, ask questions and
decide the right category with your team. Maybe the store has a nature
theme, but has too many plastic novelties mixed in. Consider adding your
definition with this Icon.
Icon: Switch to a more recognizable/official icon.
Something like the
Certification Mark
of FLO International or
Certified Fair Trade
logo 
of Transfair USA. Transfair
USA is actually a member of FLO, whom has been working on "the harmonization
of process labels." Unfortunately, FLO has adopted "a very strict procedure
with (their) logo", that arguably runs counter to the goals of harmonization,
and in my initial attempts to secure permission to reproduce it we have been
denied the right to do so. On the other hand, we have already received
permission to adopt the Transfair graphic, which is currently used in the US
and Canada. Also note that the Transfair logo is effectively two-tone, as
opposed to the FLO logo's three tones, and while it might need to be
simplified—like so 
—it
also seems to convey more meaningful information.
19 used : 0 misused : 1 redefined : 1 missing
Sells regionally and organically grown produce. Some
also sell flowers, hand crafted items, baked goods, wine, wool, even regional
cookbooks. Small family farms are kept going and the countryside remains
green. Food doesn't have to travel far, so it's nice and fresh. You can
experience the changing seasons as each new crop takes its turn showing
up at the market, which is often very neighborly.
Icon: Solid apple in circle, for consistency with "Organic Produce /
Natural Food Shop". Perhaps the apples should be the same size as well?
A better symbol still would be a bushel of apples, this most closely matches/
completes the apple-based food symbols.
39 used : 2 misused : 0 redefined : 1 missing
food is grown without pesticides or synthetic fertilizers,
and no chemicals or waxes are added after harvesting. If processed, it
is usually prepared in a way to maximize the nutritional value. May also
include fair trade practices. Some supermarkets have a few kinds of organic
vegetables amidst a large selection of conventionally grown produce. Should
this store get the organic food Icon? You have to decide.
30 used
the emphasis is on wholesome and healthful, fresh foods e.g;
organic or locally grown ingredients, free range or cruelty-free
animal products; if any at all i.e. vegan. Many ethnic restaurants easily
satisfy these criteria.
10 used
where food scraps, leaves and garden trimmings are turned into rich new
soil, with the help of worms, containment bins and Mother Nature. Large-scale
or demonstration project, information and resources for home and garden
composting. May include drop-off site for food scraps, or good place to
buy locally produced compost.
27 used
second-hand shop, flea market, repair shop or materials exchange. Decide
whether all second-hand shops should be included, or only those run by a
charity. You can select the top ten, or choose another criterion. Significant
reused buildings and other examples of reuse can be included.
26 used : 2 misused
drop-off site for materials that can be reprocessed or refilled. Businesses
that buy, work with or sell products made from recycled materials. City
program information contacts. Can include good examples of places where
recycled materials are in use.
Icon: Keep the icon. This note is to emphasize that the existing icon is
an international standard. In addition many alternate symbols such as
the German `Green Dot' have distinctly different meanings.
Air
!!!!
21 used : 2 misused : 2 redefined
place to see animals in the wild. Sites may be delicate nesting areas or
habitats, so Green Maps should therefore stress
that people must approach with care and understanding. Officially recognized
sites as well as locally-known sites could be accompanied by rules for
viewing, and details on the species you might see.
Icon: Binoculars
4 used : 0 misused : 0 redefined : 1 missing
good area to view insects and bugs as they fly or crawl though life.
6 used
Used to indicate prevailing direction of birds' seasonal migrations if
regular flight pattern is established. May also be any other good place to
watch flocks of birds overhead.
8 used
sometimes difficult to pinpoint, but these places have a powerful
effect on quality of life. Noise can come from traffic, industrial sources,
airports, quarries, heavy equipment, transportation terminals etc.
16 used
anything from industrial smokestacks and truck routes to poorly-run
composting projects.
7 used
A dark vantage point that allows unobstructed views of the heavens ideal
for watching auroras, star-gazing, meteors, etc.
2 used
favorite place to see what makes the city's environment special. Seek suggestions broadly for these sites.
9 used
wonderful spot to relax and enjoy the sunset, most likely outdoors.Great
sunrise spots can also be marked with this symbol.
Wind Power (Wind Energy Site):
2 used
wind turbines and windmills harness energy that is generated by the wind
on this site. Can be a small system that operates a simple pump or a large
electricity generating facility. Can indicate wind power information resources.
Solar Power (Solar Energy Site):
15 used
Passive heating (e.g; adobe) or cooling, solar panels, etc. Either existing
installations, or related information sources and services.
3 used
where solid waste is burned at high temperatures, sometimes capturing the
embodied energy (waste-to-fuel). The volume is reduced considerably, but in
some countries, the resulting ash is considered hazardous waste. Often, toxics
are emitted from the smokestacks as air pollution. Can include incinerators
at hospitals, crematoriums, large institutions and municipal facilities.
Transport
27 used : 6 misused : 0 redefined: 1 missing
good place to buy, borrow or rent bicycles, work bikes
and other kinds of human-powered vehicles. Organizations and places to
find out about bike safety or advocacy. This Icon Can also be
used to indicate other kinds of bike-friendly services and sites.
Icon: Generalize to human-powered vehicles somehow? Pedals and rollerskates?
4 used : 0 misused : 0 redefined : 1 missing
Street or public area that prohibits motor vehicles, and other
auto-free areas. Access by vehicles might be allowed part time.
Icon: More intuitive/less abstract? Hard to do for a linear symbol.
Is there an existing symbology somewhere?
Mountain biking, horseback riding, hiking, etc.
This should
help cover a lot of the outdoor activities people keep inventing local icons
for.
Icon: There is a cartographic symbol for off-road paths.
1 used : 4 missing
these paths are usually painted but are on the same street level as car
traffic. You can designate a favorite green scenic route of your own.
Icon: More intuitive/less abstract? Hard to do for a linear symbol.
Is there an existing symbology somewhere?
2 used : 5 missing
separated from cars by curb, barricade, etc. On bridges, often shared
with pedestrians. Green Maps can be merged with existing bike/trail/ commuting
maps or simply mention good places to obtain these other maps.
Icon: More intuitive/less abstract? Hard to do for a linear symbol.
Is there an existing symbology somewhere? Perhaps bike tire-tracks.
12 used : 2 misused
attended parking area, or recommended area with adequate lighting and
a bike rack.
Icon: This icon can be very hard to distinguish at small sizes...
19 used : 1 misused : 1 redefined : 1 missing
follow a path around an especially interesting area. Walks can be
established or recommended by the Green Map team but should be non-intrusive to
sensitive areas. Icon can be used to designate a running path through a natural
area.
7 used
water-based transport system for passengers and freight. Can be a very
refreshing and efficient way to commute and travel. Can include water-taxis,
which run on an as-needed basis.
18 used : 1.5 misused : 2.5 redefined
multi-modal transit hub served by more than one kind of public
transport system, central station or depot for transit passengers. Often
has other services available.
Icon: While relatively abstract this icon works relatively well
though it should perhaps be revisited. If preserved, versions in other
orientations (the eight of a compass rose) might be useful
for indicating the direction of service.
20 used : 1 misused
subway, bus or trolley stop. Bus stops may be too numerous to
map, except in proximity to remote green sites.
Icon: While relatively abstract this icon works relatively well
though it should perhaps be revisited. If preserved, versions in other
orientations (the eight of a compass rose) might be useful
for indicating the direction of service.
7 used : 1 misused : 1 redefined
Trolley stop. Transportation by eco-efficient light rail runs through
these areas.
The focus of public-transit symbols should probably be service-
capacity/range/speed and not mode. Were one to break things down by mode buses
and subways are necessary to round out the list; ferry symbols are OK
since many also allow cars, which is a special service indication.
Suggested Icons: If kept and other modes added
5 used : 0 misused : 1 redefined
parking lot for cars (or bikes) with a convenient public transport
connection. Sometimes Park & Rides are subsidized or free to encourage
drivers not to bring cars into the center of the city.
Icon: Use 
,
it contains the basic P with additional context.
Alternative Vehicle Fueling (Alternative Fule / Vehicle Station):
8 used!!
Where you can top up an alternative fuel vehicle (including electric).
Could be a place to buy or research alternative fuel vehicles and find out
more about the true environmental costs of producing fuel.
Icon: A gas-pump nozzle with the earth or a leaf, as a drop coming out
Car or ride-sharing programs. !!
Icon: v2 "Alternative Vehicle/Fuel Station" icon
4 used
your electric vehicle can be re-charged by solar power (or the conventional
power grid) while parking here.
Merged into "Alternative Vehicle Fueling"
Society
Often, certain populations coincide with unfavorable land uses; which
came first is often a chicken-and-egg problem and specific to an individual
site. These icons are a simple means of indicating various forms of equity.
Icons: Based on Eugene Turner's application of Chernoff faces.
Create two sets, one as outlines of faces, and the other as filled in.
12 used : 2 misused
place where people consistently gather or post messages to respond to
official political actions and decisions. May not all be related directly to
environment--can be social, historic or cultural protest point.
Icon: Kyoto fist or a banner similar to 
25 used : 1 misused : 2 redefined
service or office that helps individuals or society in general
to develop environmentally sound policies and practices. Might include
alternative and governmental agencies, grassroots organizations, trade
organizations and political parties, non-profit social services, environmental
justice and native rights organizations.
18 used : 0 misused : 1 redefined : 1 missing
might be socially responsible non-profit or educational group, club or
advocacy group that contributes to the local environment in important
ways.
Icon: The current symbol has many pre-existing meanings.
13 used : 1 misused
of great importance, generally, to the community. Sites that impart a
sense of place. Co-housing, natural buildings and schools, or Buildings
with historic, cultural, architectural value could also be included.
25 used
edifice, institution, monument or unmarked historical area with special
significance to the city's environment and sense of place.
How is this unique vs. say Significant Building?!
6 used
may refer to indigenous, pioneer or migrated peoples' traditions.
Might not be assimilated into prevailing culture. May be resources for
learning about or visiting people living in traditional, more ecologically
self-sufficient ways.
30 used : 1 misused : 2 redefined
these contribute to the city's environment and sense
of place in many important ways. Non-institutional resources, monuments
and places, even temporary events (monthly swap meet, annual eco-fair)
may be included
How is this unique?!!
22 used : 0 misused : 1 redefined
these are either entirely about nature's interconnections with urban
culture, or frequently include the environment in programs and exhibitions.
You may opt to limit your selection to those featuring sustainable ways of
living, social responsibility or other locally relevant criteria.
28 used : 5 misused : 1 redefined
can range from intensive programs within a regular school system or
university, to places offering one-time environmental workshops and lectures
to the public. Could be a hands-on learning center or technical school.
Icon: 
30 used : 1 miused : 3 redefined
ecologically oriented artworks, may include earthworks or public artor
performance art. Could>/b> be resources for making eco art, information
on events or schools related to environmental art.
16 used : 2 misused
place where clubs, meetings and social gatherings involving the whole
community are held. May be a formalized community center, or one established
though common use.
Cultural Performance (World Music):
10 used : 2 misused
May include world music venues such as; folk, participatory, ethnic,
improvisation, classical, jazz, as interpreted locally. A place to listen
to and play music
Icon: The traditional Greek comedy/drama masks
16 used : 1 misused
places to contemplate nature or spiritual pursuit, may be an organized
religion's sanctuary or environmental program, or a profoundly beautiful
place, even an old cemetery or 'oasis of calm' in a busy area.
This is far beyond the scope of an environmental map. It is highly subjective,
and onc could argue that most any nature spot qualifies, making this redundant.
15 used
alternative medicine source, herbal, homeopathic, eastern, etc.
Spas, apothecaries, clinics, health clubs and yoga are possible examples.
This is far beyond the scope of an environmental map.
Supplementary
This section of symbols is slightly different in that they are not
features themselves, but provide additional information about features.
