That seems to be bash on linux. Perhaps, this will help. The double quotes are to handle file names with spaces and the like in them. $ for tiffile in *.til; do echo gdal_translate -of SRTMHGT "$tiffile" `basename "$tiffile" .til`.hgt; done gdal_translate -of SRTMHGT xyz.til xyz.hgt $ ls xyz.til Randolph J.

Hi,
Uggly scripts I use…
- tif2hgt.sh: for tiffile in *.tif;do gdal_translate -of SRTMHGT $tiffile $tiffile.hgt; done
- tif_dim.sh (if .tif downloaded by phyghtmap are "too" small…) for tiffile in *.tif;do gdalwarp -of GTiff -srcnodata 32767 -rcs -order 3 -ts 1201 1201 -multi $tiffile $tiffile.TIF; done
Renaming is not integrated within the scripts… 🙁 (removing first extension) Perhaps the second can help… 🙄
On Linux !

Hi Carlos,
are you talking about geotiff format? I think someone documented how that format can be converted to *.hgt. Can you post a link to such a file?

Hi Gerd They are downloaded by phyghtmap. This is what I found digging into phyghtmap files: |def getSRTMFileServer(self, resolution, srtmVersion):|| || if srtmVersion == 2.1:|| || return "https://dds.cr.usgs.gov/srtm/version2_1/SRTM{0:d}".format(resolution)|| || elif srtmVersion == 3.0:|| || if resolution == 1:|| || urlRe = "https://earthexplorer.usgs.gov/download/8360/SRTM1{:s}V3/GEOTIFF/EE"|| || elif resolution == 3:|| || urlRe = "https://earthexplorer.usgs.gov/download/4960/SRTM3{:s}V2/GEOTIFF3/EE"|| || return urlRe| They should come from the second URL above.

Hi Carlos,
sorry for the late response. I found no hint on the phyghtmap page http://katze.tfiu.de/projects/phyghtmap/ regarding a new format for srtm data. The hgt format is not compressed. Do you know from where these 12.4 MB files came from?
Gerd

I use phyghtmap to build contour lines and also to download hgt data that I then use to build DEM maps with mkgmap. For a long time, SRTM1 files (and also VFP1) have all been ~24.7 MB in size, but lately (I don't remember since when) SRTM1 are also served as 12.4 MB files. phyghtmap is able to generate contour lines from those small files, as they seem to contain the same information but with a different compression ratio, but mkgmap fails to read them, and report them as missing. Would it be possible to get support for such files in mkgmap? _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
