Hi, I have observed weird road speeds when using current mkgmap r2977. See this way: http://www.openstreetmap.org/way/227105752 It has no maxspeed tag. It should be rendered as primary road, speed class 4. This is what I get, if I disable including "roadspeed" file from default style. With "roadspeed" all is different and depends on tile area. I have prepared sample data, where this road get speed class 6. Croping a bit tile area (outside the road) changes speed class to 3. See picture showing both cases, dark blue is class 6, green is class 3: http://files.mkgmap.org.uk/download/173/speed-problem.png I have prepared an example of source data: http://files.mkgmap.org.uk/download/172/speed-problem.7z It contains source data and a poly file for cropping. I have included batches, that I have used for creating maps. Actually I'm not sure, what is the behavior of mkgmap:road-speed-class tag. I couldn't find any description. For example if I define a road like [0x03 road_class=3 road_speed=4 resolution 19], does it create mkgmap:road-speed-class=4? -- Best regards, Andrzej
