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

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?
Gerd

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

An: Development list for mkgmap
Betreff: [mkgmap-dev] "Small" SRTM1 files and DEM maps
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?
