Free map data of major Rivers, Mountains, Lakes - not from OSM - suitable for overviewmap/worldmap creation
I know such things exist - but not really where. OSM data is too detailed and impossible to extract that data without getting unimportant data. My plan would be to create a 20-50MB big worldmap - non routable - that people could use on their GPS device instead of the Garmin worldmap / preinstalled routable Worldmaps. Together with the overview maps for Desktop use, that would be perfect addition (create a worldwide map resolution 12-17). We could use OSM for that, but then one would need to limit to big cities (population works well for filtering), capitals, sea/land, motorways. Other OSM data is not really that suitable. It would be cool to have some more data like major mountains, major rivers, maybe major railways, (something else?).? Filtering the important ones from OSM won't really work (also rivers should be lines, not polygons to keep data amount small). Any ideas on that?
Felix, Maybe you can have a look at http://www.naturalearthdata.com/

Ah yes, thanks. That's the one I once found. So how can we use ESRI shapefiles with mkgmap? osmfilter/osmconvert? They do osm to Esri, but also the other way round? Due to terms of use, it's not possible to use CGPSmapper (besides I don#t know my way around with cgpsmapper anymore). A nice worldwide overviewmap, would really help in making the experience of using mgkmap created detailed maps, much more streamlined/better. Or is there already a free worldmap for Garmin around?

I think you can use JOSM to import the vector data, and save it in osm format, or maybe use gpsbabel, I dont know exactly, only had a quick look to extract some major cities once. But what I have seen is that there is a lot we can use on that site.

Hmm I only know some free ones that are not so legal and easy to find ;-)
yes I also think it's the perfect addition for overview maps / basemaps... and it doesn't have the problem of OSM about importance... Also some topographic data in there, is better then what is in OSM... On 10.05.2013 16:16, Minko wrote:
