This may be a really dumb question and I apologize if it is - this is pretty new to me.
I'm using the HGT files from https://dds.cr.usgs.gov/srtm/version2_1/SRTM3/ with a program currently and want to upgrade to more recent, better quality, data.
I downloaded the SRTM 90m Digital Elevation Database v4.1 ZIP file and see that HGT files aren't one of the formats supplied.
How can I convert what is supplied into HGT files with the same naming convention as what I currently have?
Is that possible or do I need to modify my application to suit this other format?
