Hi,
I have a .dem file which i'm using as height and .tif file as texture. Height
file has latitude and longitude coordinate system but texture file do not. I
want to create .osg file combining both using osgdem... -cs "+proj=latlong
+datum=WGS84" -o ... but its giving some error..
Should both files(height & texture) contain same coordinate system(geogcs) for
me to able to use osgdem, for i want to retrieve latitude and longitude data at
each point of the terrain?
I have given the output of gdalinfo of both files down. Can you help me with
gdal(command) to convert texture file to same coordinate system as height file
so that i can use them to create .osg file using osgdem and then extract
latitude&longitude data for each poit on the terrain.
