Hi all, Happy to report more progress on the map features charts :)
http://www.mediafire.com/file/1yk31opux7yob1a/Schematroll_2_01_23_sept_2010.zip -i have included the mapnik schema chart (list of features that mapnik supports) -the TIGER Map features -re-organized with categories and descriptions -the USGS NHD map features -the canvec features organized a bit more -included the pdf catelogues for each feature set so you can source back to it So now that i've collected most of the data, i can bring it all into 1 large chart, which shows all of the features and the category naming that each country/dataset uses to describe the features. Once that's done, i can then transfter and perge the rows where there are feature matches, and slightly different descriptions. I can then add in the png file links copied from the nrcan and usgs paper maps and from the osm map feature page, to the master spreadsheet Because there are so many variants in tagging, i think the best route to take is to just a single document that just has 4 columns for 'DictionaryKey' 'DictionaryValue' then 'SchemaTrollKey' and 'SchemaTrollValue', that way, whenever you need to figure out a map feature, you can look it up in the chart, and and then adjust the reference to something better where needed. So the source datasets map features along with the garmin features acts as the 'basemap legend', where when it gets combined it becomes a very good international set of map features, which have been designed by National Cartography agencies around the world. Is it the best? No, but it's pretty close :) And the definitions from each map feature can easily be understood, so there is really no question on what exactly is being represented. So for the planet.osm tag-popularity contest, it's actually better to use these map features as again another source of Data, like another dataset. Since it does change often, its really only the top frequently used features that can be used to give it a well-rounded view. The rest of those less common map features, are listed in the 'DictionaryKeyValue' list. Anyway, that's it for now, i'll check back in a couple weeks with progress :) Again, if anyone wants to help with tag-matching and detailing, just ask :) and im happy to post the latest version to a googledocs spreadsheet.
