From now on, we'll assume you are using SRTM-3 data. Unless otherwise noted, the process for SRTM-1 is identical. | From now on, we'll assume you are using SRTM-3 data. Unless otherwise noted, the process for SRTM-1 is identical. | ||

(The reason why the directories are called SRTM-30 is because genapts will look for a few known, hardcoded directories in it's working directory. SRTM-30 is one of them and is the least confusing in that list.) | ||

After that, open the commandline (Run > cmd.exe) and change into the base directory. Then type this: ('''NOTE:''' | Now we've got the data, we need to convert it into something of use to TerraGear.
