SRTM rendering issue on Windows (Endianness?)

[xtassin]

Hi,

I get the following result when rendering with SRTM data. Not sure what is causing the undulated shape but data seems to be somewhat meaningful at the top of each "wave"

I originally thought it could be an endianness problem on windows but after conversion of the SRTM file, it appears to be something else.

I use an original (unprocessed) version2_1 SRTM3 HGT file
