Hi Andrzej, reg. screen shots: I created my two screenshots this way: 1) locate a position -> create 1st screenshot -> leave MapSource 2) replace map content (I just rename dirs, both maps are created with the same options, just different binaries) 3) open MapSource, press Strg+G two times, create 2nd screenshot I think the same works with Basecamp, both remember the position in the map in this case. You can also use Strg+T to jump to a position.
I've also tested quality again now and found that DEM data is clearly better when DEM bbox is aligned to hgt raster. So, yes, we should align, and I was wrong, there is no need to change splitter for that, we just have to align the DEM bbox :-) This allows to get the best result out of a hgt file without using a dem-dist value that is lower than the resolution of the hgt file. Question is if anything is improved with e.g. dem-dists=3312,... when dem-dists=9942 gives the best possible result? Gerd P.S. please review new patch, last one did not use moved value for right boundary ________________________________________ Von: mkgmap-dev <mkgmap-dev-boun...@lists.mkgmap.org.uk> im Auftrag von Andrzej Popowski <po...@poczta.onet.pl> Gesendet: Dienstag, 16.

I have ceated 2 maps, one with god alignment and second with left and top edge moved by 1/2 HGT pixel size. I have used HGT with resolution 3600, so the movement was about 15m. I think shading is the same on both maps. There is no obvious change, but I can't make BaseCamp to display maps at exactly the same position, so there is a small movement of all objects. See pictures: http://files.mkgmap.org.uk/download/396/hgt-aligned.png http://files.mkgmap.org.uk/download/397/hgt-nonaligned.png DEM layer is the same for both maps, position and size exactly the same. I have found, why shading on your map looks more detailed. You have created only single layer of DEM, while I use 4 layers. Shading with multiple layers looks softer. Another weird effect is that with single layer, shading gets softer, when you set "Map Detail" to higher in Mapsource. With multilayer is opposite, probably Mapsource switches between layers. -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
