[mkgmap-dev] hgt2osm questions

Mon Nov 13 12:28:13 GMT 2017

Hi all,

Maybe a silly question from a user ... a happy user ...

Will it be possible to use this new tool from Frank to
enrich the OSM-files (*.img) with elevation data (DEM) ???

I use the OpenMTBmap from Felix with modified .TYP-files,
for this I use TypWiz5 from Nick.

Or do I have to wait until Felix will hopefully
add the DEM subfiles ???

Right now I get my tracks out of Basecamp without
elevation data :-(

Then I add the elevation data with a WWW-solution,
selfmade, with the necessary .hgt-files.
Mainly 1sec from USGS, in the very North from ViewfinderPanoramas,
some only 3sec resolution.
For Europe and Eurasia this files sum up to 50GB,
far too much for my Internet provider.
So I implemented 2 solutions:

Always online: http://tinyurl.com/odm6av7
     Southern Bavaria, some of Tyrol, only 4 .hgt files

On a NAS on my desk: http://tinyurl.com/yact8gm6
     Europe and Eurasia, more then 3000 .hgt files

The Javascript, if anybody is interested: http://tinyurl.com/ychhdpxj
