[mkgmap-dev] DEM and SRTM hgt files: size too small

Thu Nov 1 09:16:19 GMT 2018

Hi,

I started to play with maps with DEM, but run into a problem:
viewfinderpanoramas.org provides hgt files, but only for some areas.
The SRTM1v3.0 data is using geotiff. No problem, you can convert them
with gdal_translate and fill the missing areas. Works fine for below N50,
but starting with N50, the data is much smaller and this leads to the
following error:
SEVERE (HGTReader): 71200154.osm.pbf: file /data/OSM/data/hgt/N50E012.hgt has unexpected size 12970802 and is ignored
SEVERE (HGTReader): 71200154.osm.pbf: file /data/OSM/data/hgt/N50E013.hgt has unexpected size 12970802 and is ignored
SEVERE (HGTReader): 71200159.osm.pbf: file /data/OSM/data/hgt/N50E014.hgt has unexpected size 12970802 and is ignored

Any ideas how to solve the problem?
