[gdal-dev] satellite photo height data

[Chaitanya kumar CH]

weixj2003ld,

First you have to locate the corner pixels corresponding to the lat/longs
you indicated. Go through (http://www.gdal.org/ogr/osr_tutorial.html) to do
that. Use "WGS84" system for lat/longs.

Use GDALRasterIO() (http://www.gdal.org/gdal_tutorial.html) to retrieve the
pixels from the required area.
