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. height file:: Driver: USGSDEM/USGS Optional ASCII DEM (and CDED) Size is 1802, 1802 Coordinate System is: GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID["WGS 84",6378137,298.257223563, AUTHORITY["EPSG","7030"]], TOWGS84[0,0,0,0,0,0,0], AUTHORITY["EPSG","6326"]], PRIMEM["Greenwich",0, AUTHORITY["EPSG","8901"]], UNIT["degree",0.0174532925199433, AUTHORITY["EPSG","9108"]], AXIS["Lat",NORTH], AXIS["Long",EAST], AUTHORITY["EPSG","4326"]] Origin = (75.749861111111116,34.750416666666666) Pixel Size = (0.000277777777778,-0.000277777777778) Metadata: AREA_OR_POINT=Point Corner Coordinates: Upper Left ( 75.7498611, 34.7504167) ( 75d44'59.50"E, 34d45'1.50"N) Lower Left ( 75.7498611, 34.2498611) ( 75d44'59.50"E, 34d14'59.50"N) Upper Right ( 76.2504167, 34.7504167) ( 76d15'1.50"E, 34d45'1.50"N) Lower Right ( 76.2504167, 34.2498611) ( 76d15'1.50"E, 34d14'59.50"N) Center ( 76.0001389, 34.5001389) ( 76d 0'0.50"E, 34d30'0.50"N) Band 1 Block=1802x1802 Type=Int16, ColorInterp=Undefined NoData Value=-32767 Unit Type: m texture file:: Driver: GTiff/GeoTIFF Size is 1802, 1802 Coordinate System is `' Metadata: TIFFTAG_SOFTWARE=IrfanView TIFFTAG_XRESOLUTION=762 TIFFTAG_YRESOLUTION=762 TIFFTAG_RESOLUTIONUNIT=2 (pixels/inch) Corner Coordinates: Upper Left ( 0.0, 0.0) Lower Left ( 0.0, 1802.0) Upper Right ( 1802.0, 0.0) Lower Right ( 1802.0, 1802.0) Center ( 901.0, 901.0) Band 1 Block=1802x1 Type=Byte, ColorInterp=Red Band 2 Block=1802x1 Type=Byte, ColorInterp=Green Band 3 Block=1802x1 Type=Byte, ColorInterp=Blue Thank you!
