Free map data of major Rivers, Mountains, Lakes - not from OSM - suitable for overviewmap/worldmap creation
by Felix Hartmann 10 May '13

10 May '13

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?

overview2 branch -- sea not rendered at resolution 12
by Felix Hartmann 10 May '13

10 May '13

Well, I first thought it would be a Mapsource/Basecamp bug, but actually mkgmap overview2 is not rendering the sea tiles down to resolution 12. The lowest resolution working is resolution 14... -- at 13 some sea is rendered, at 12 no sea at all is rendered. I think unlike in my earlier reply to Henning - that this is some internal bug (maybe related to that before 13 was the resolution of the overview map) Else I really think that the branch can be merged. It is really working well now... - and I played around a lot with it. Only other thing is maybe to have an option to delete / not delete the ovm*.img files after creation. Resolution 12 is great for continent maps like Europe (not fully needed - 14 could do), or Asia (13 is a must, 12 would be much better). Great stuff!

Support place polygons in preprocessed bounds
by WanMil 10 May '13

10 May '13

Hi, I want to support place boundaries in the preprocessed bounds which was requested sometime ago. After having a look at the source code I guess that we can support 4 types of place categories. @Gerd: The BoundaryQuadTree.mkgmapTagsArray can have up to 16 entries because the index is stored as short. Correct? Which place tags are required most? place=city place=town place=village place=hamlet ...??? Please let me know about you most favourite place tags. Have fun! WanMil

[PATCH v1] Drop old preprocessed boundary legacy format
by WanMil 10 May '13

10 May '13

Attached patch drops the support for the old boundary legacy format. The boundary preprocessor does not create files in this format since April 2012. I think it's time to drop the support for such old data to simplify the code. @Gerd: Can you please have a short look if I am right that these parts are no longer used? WanMil

Need contour lines
by Doug and Cathy Hull 09 May '13

09 May '13

I'm trying to create a Garmin .img file with contour lines for biking. I download the OSM file, but it does not have contours even though they show up on the osm.org site. Can anyone give some advice to a novice? Thanks, Doug Hull Victoria, BC
