Hi all,

I'm hoping that im being of some help here :)

For those who might not know, im taking on the challenge of trying to organize all of the Map Features into a universal system. I'm calling it 'SchemaTroll 2.01' http://wiki.openstreetmap.org/wiki/SchemaTroll_2.01

I have now completed an analysis of the Garmin Map Features, and created a spreadsheet which lists it all.

I used http://freegeographytools.com/2008/garmin-gps-unit-waypoint-icons-table - for the icons and feature categories the mkgmap .csv file from the 'mkgmap-r1709-src' and cross-referenced the big list of Map features, with the smaller list of OSM tags that it supports. http://www.geopainting.com/en/ - GPSMapEdit provides a nice detailed category listing for each map feature. .. and in it's 0x#### form. So it was easy to match-up the GarminID's with the mkgmap ID's ... as some where switched around. http://www8.garmin.com/cartography/mapSource/mapLegend.html - has a detailed list of all the map features that gets supported (for MapSource)

I also included 2 columns for 'SchemaTroll KEY' and SchemaTroll Value' these are where i simply went through it and guessed as to what the tags could possibly be in the future.

For the OSM Map Features, there are a few (a whole lot) of Tag Proposals that need to be made. So i'm leaving that upto the Wikians to fix up the wiki. I'm just trying to help it along.

Ideally, it would be great to see an OSM tag for each of the Garmin Map Features, as the map can actually support the customized map, of upto 700 or so features. I noticed that many features are duplicated across different Garmin ID's and Many Garmin ID's support multiple OSM tags.

So basically, im trying to get the whole chart filled in, with the best known map features, and using the Wiki as the primary source. And over on my version of the Spreadsheet, im keeping a list of Features that need to be proposed, and updating my own spreadsheet. Which i hope to make available in the next month or so. (it's going through so many changes) :)

For those who know how to use Gitorious I just converted the file to .csv and Pushed the latest changes http://gitorious.org/wikimap-books/wikimap-books-legend

and here's the GoogleDocs Chart

Hopefully someone will find some use for it :)

Cheers, Sam

P.S How often does the osm map features .csv file get updated?

Hi Sam, For mkgmap purposes, the map_features.csv file is deprecated. As I understand it (this was before I started using mkgmap) it was initially a reference for helping mkgmap to convert OSM objects to Garmin types. But now this conversion is done via the style rule system, so you will find that many more OSM objects are mapped to Garmin types than is apparent just from the map_features.csv file. To understand the current "mapping" of OSM features, have a read through the various style files in the default directory of the SVN: http://www.mkgmap.org.uk/svn/wsvn/mkgmap/resources/styles/default/ You'll probably be most interested in the lines, points, polygons and relations files. Taking an example 0x6612 which you say is not supported by mkgmap. If you open the points style file you'll see that there is in fact a rule to use this type: leisure=nature_reserve & name=* [0x6612 resolution 18] Another thing to look at if you're interested in Garmin POI types is the spreadsheet I put together a while back: http://www.cferrero.net/maps/downloads/garmin_feature_list.xls This is a work in progress and it's still not entirely complete. Finally, beware that http://www8.garmin.com/cartography/mapSource/mapLegend.html is not entirely complete nor correct as I don't think they have updated this for a while and the POIs supported by MapSource seem to change with every new version. Finally finally, of great importance to Garmin GPS users is the ability to search for particular POI types. Not all the Garmin type codes are searchable - it is important when considering the conversion of OSM objects to Garmin types whether you want the resulting POI to be searchable on the GPS unit, and if so, what category you want it to appear in. Your spreadsheet would be even more useful if it showed whether a Garmin type was searchable and if so, what category it appears in. You can use my spreadsheet for this. Finally finally finally (!) - what is column O? It looks like the zoom level mapping for Garmin POIs. If so, then this information isn't that useful as it's arbitrary (though carefully selected).
