My starting file of interest is an ASC file with the following gdalinfo
Driver: AAIGrid/Arc/Info ASCII Grid Files: sd_1_3_110805.asc Size is 11880, 9720 Coordinate System is `' Origin = (-117.900000000000010,33.399999999999991) Pixel Size = (0.000092592592593,-0.000092592592593) Corner Coordinates: Upper Left (-117.9000000, 33.4000000) Lower Left (-117.9000000, 32.5000000) Upper Right (-116.8000000, 33.4000000) Lower Right (-116.8000000, 32.5000000) Center (-117.3500000, 32.9500000) Band 1 Block=11880x1 Type=Float32, ColorInterp=Undefined NoData Value=-9999
To translate to a tiff I have tried:
gdal_translate sd_1_3_110805.asc lj.tif
Subsequently I would like to change the projection to UTM flat to ultimately create a 3d model of flat vs geocentric terrain.
Unless I have specified using a geocentric model to osgdem (VirtualPlanetBuilder) to build the 3d terrain model, my model always comes out mirror image (north is south etc...). So I desire to use a flat terrain model... what parameters should I be using to get to a geotiff with the correct projection to start with?
