i have lots of data which was coordinated with gdal some programatic way at below:
gdal_translate -of GTiff -a_ullr %s %s %s %s -a_srs EPSG:3857 %s/%s %s/%s.tif
then for tiling them all i am building virtual dataset with this:
gdalbuilvrt some.vrt *.tif
for getting its geographic info with gdalinfo i am getting this result:
Coordinate System is: PROJCS["unnamed", GEOGCS[, DATUM["unknown", SPHEROID["unretrievable - using WGS84",6378137,298.257223563]], PRIMEM["Greenwich",0], UNIT["degree",0.0174532925199433]], UNIT["metre",1, AUTHORITY["EPSG","9001"]], AUTHORITY["EPSG","3857"]] Origin = (.......,.......) Pixel Size = (4.777314268465985,-4.777314267784062) Metadata: AREA_OR_POINT=Area Image Structure Metadata: INTERLEAVE=PIXEL Corner Coordinates: Upper Left ( ..... Band 1 Block=2816x1 Type=Byte, ColorInterp=Red Band 2 Block=2816x1 Type=Byte, ColorInterp=Green Band 3 Block=2816x1 Type=Byte, ColorInterp=Blue
then with this virtual dataset for gettin geodeitc tile i am calling gdal2tiles.py with profil geodetic but i am getting this result:
ERROR 1: No PROJ.4 translation for source SRS, coordinate transformation initialization has failed. Generating Base Tiles: Generating Overview Tiles:
where i am wrong i havent found yet. but when running gdal2tiles.py for only one tif file it is working and in global mapper it returns true result...
how can i tile my image pls i need your helps?
