[Gdal-dev] SRTM file format

[Gillian Walter]

Hi,

For those of you who also use openev, Andrey has added a neat tool for 
reading raw binary files (it adds a menu entry File/Open Raw... that 
launches a gui allowing you to specify lines, samples, number of bands, 
interleaving, datatype, header size, byte swapping).  This should 
eliminate the need to manually create header files for viewing flat 
binary files in openev.  This tool is new though, so you'd have to get 
it from cvs.
