Greetings, I have a need for corrected version 4 of the 3 arc second SRTM data. This is only available as a AAIGrid format for some reason, not SRTM HGT.
I've pulled the 30x30 degree tiles from here in AAIGrid: http://srtm.csi.cgiar.org/srtmdata/ gdal_translate requires the input file to match the resolution of the SRTM output, which is 1201 x 1201 with 1 overlap pixel. So I broke the 30x30 into 1201 x 1201 AAIGrid files first: gdal_retile.py -of AAIGrid -v -ps 1201 1201 -overlap 1 -v -csv csv.csv -targetDir out cut_n00w090.asc Then to the out/ directory, and use gdal_translate: gdal_translate -of SRTMHGT cut_n00w090_01_01.asc output.hgt This appears to work and gives a warning of: Warning 1: Expected output filename is N29W090.HGT Question 1: Is there a way to have it auto name the output file? I'd assume if it knows what it's suppose to be named, there should be a flag to automatically name it that. I can't find that, and need it to convert several thousand of these files. Question 2: Is my re-tiling correct and method correct to convert to SRTM 3 arc second HGT files? Is there a better way to do any of this? I did search the archives and was unable to find much else as the SRTM doesn't look that popular of a format to process. -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/gdal-dev
