<br>
I really don't know. I use a very similar batch file to create my map in gmapi format and I don't see these errros with my map.<br>
I can reproduce it with your gmapi.<br>
In my batch file I have<br>
set demOpts=--dem=f:\srtm3_1_zip,f:\srtm3_1_comp,f:\srtm3_zip,f:\srtm3 --dem-poly=map.poly --dem-dists=4518 --dem-interpolation=bilinear --overview-dem-dist=88000<br>
<br>
Interesting candidates are --overview-dem-dist and --dem-poly. If this doesn't help I'll try to reproduce with your options...<br>
<br>
Gerd<br>

Betreff: Re: [mkgmap-dev] Elevation data just partially accessable by Basecamp<br>
<br>
Good Morning Gerd,<br>
<br>
thank you very much for your fast response. The gmapi format was created just by replacing the option --gmapsupp by --gmap in the script. All other options remain the same.<br>
<br>
The point I do not understand is: Why does same data, same generation process works fine when generating an image format (--gmapsupp) but not when generating a gmapi format (--gmap). Is there a difference in indexing the DEM tiles on both formats which could
cause this issue? What confuses Basecamp (and me) to correctly show Hill Shading and 3D View on gmapi format but no elevation data at cursor position and no adding of elevation data to created track points?<br>
<br>
DEM tiles were calculated during generation by mkgmap. And yes, their boundaries do not match exactly those of the other tiles. But even this works fine with image format but not with gmapi format. And even with some missing HGT data theses areas just have
an elevation of 0 on image format.<br>
<br>
Thanks for any advice<br>
Kalle<br>
<br>

Hi Kalle,<br>
<br>
welcome to the list!<br>
Your *.bat doesn't show how you create the gmapi format. If you just add --gmapi to the options in 02_run_mkgmap.bat I see no reason for a problem presuming that all *.hgt files are found.<br>
You describe a problem that I've only seen when DEM tiles are calculated separately, so that the tile boundaries don't match those of the other map tiles.<br>
<br>
Does that help?<br>
<br>
Gerd<br>

Betreff: [mkgmap-dev] Elevation data just partially accessable by Basecamp<br>
<br>
Hi all,<br>
<br>
I recently tried to add DEM data to my OSM maps for Garmin. At a first look all was fine, hill shading and 3D viewing was amazing in any case. Then I had issues that Basecamp (4.7.1) can only access elevation data when the map is on an USB stick as an image.
Here elevation data is display besides the Lat/Lon for the coursor position and created tracks have elevation data.<br>
When I generate these maps in .gmap format or install (large) maps by registry (gmaptool 0973) the DEM data seems to be included in the map, because Hill Shading as well as 3D Viewing works fine, but in Basecamp created tracks do not have elevation information
and the coursor position (bottom left corner) shows only Lat/Lon but no elevation.<br>
<br>
I created a small map (50 km radius) to figure out working with DEM data. This map works well on USB stick as image and even when installed by registry. When generated in .gmap format it shows the mentioned issues.<br>
<br>
I also created larger maps (whole Germany, whole Alps) which only worked with full access to elevation data on USB stick, coursor elevation displayed and track elevation data included. But same issue when installed by registry or .gmap format.<br>
<br>
What's wrong here? Are there size limitations for DEM data? Is there a difference between image on USB and the other installation options?<br>
<br>
Thank you for any hint to solve this issue and by the way for your great job on developing this software!<br>
<br>
Kind Regards<br>
Kalle<br>
