I have just added a TransforMap tag to an OpenStreetMap POI (Point of Interest) for the first time. Initially, I didn’t understand the relationship between the attributes of the POI and the different maps. This post attempts to answer my own question. Is this already documented somewhere else?
What’s on the various maps: Green, Political, Regional, Organic, etc?
http://transformap.co/, presents us with a choice of 4 maps: Green, Political, Regional and Organic. But what’s on them?
In fact there are more than 4 maps available. To see this, click on any one of the 4 maps. You will then see a map with a menu on the right hand side. If you click on “Explore other maps”, you will see that there are in fact six different maps: Organic, Regional, Fairtrade, Green, Secondhand, and the map of Identities. The TransforMap of Identities is another name for the Political Map.
Each map applies a different filter to the underlying OpenStreetMap data. Having selected a map, you can see a description of the filter by clicking on “About this Map”.
Question: For those wanting to check the precise definition, where is the “source code” for the filters?
There are a couple of consequences of this:
- POIs can appear on more than one map.
- POIs can appear on none of the TransforMap maps, even if they were entered using the TransforMap editor http://editor.transformap.co.
The TransforMap of Identities
This map is special: it is the only one that restricts the view to places in the alternative economy. This is because POIs that appear on the map of Identities must have the tag “identity” set. This tag is used to say to which community (within the alternative economy) the POI belongs. Examples of communities include Solidarity Economy, Degrowth, Commons and many more. For the full list, see http://wiki.openstreetmap.org/wiki/Proposed_features/TransforMap#Self-description_of_a_community.
Other maps may include organizations that operate within the mainstream economic system. For example, a health-food shop that is part of a multi-national chain, but which is tagged “organic=yes” will show up on the Organic Map.
Question: The name “TransformMap of Identities” seems to be too general, and takes quite a bit of investigation to work out what it really means. Is this just a temporary name? The same observation applies to the OSM tag “identity”: it seems too general.
This map shows places where locally produced items are available. Before checking “About this map”, I had assumed that it was a map of geographic regions, as this is a normal usage of the term “regional map”. I think that the title “Local Produce Map” would be clearer.
The “About this map” text says “For an item to be displayed, it must have the “regional” tag set …”. I could not find this tag on the OpenStreetMap wiki, but I’m also new to OpenStreetMap, so I probably missed it. Can anyone point me to it?
A map showing Green Spaces. (not green as in “eco”, which was my original understanding).
What is the status of the maps?
- Is there some discussion on the forum that will show how this set of maps was chosen/evolved?
- The current website is demo.transformap.co. Is there some discourse about which maps will go beyond the demo stage?
Where on the forum should this go?
I’m now looking at Engineering/Demo Maps - would that be a better home for this post?
