hello,
i'm trying to gdalwarp a google map tile geotiff its SRS is a
3857.prj
PROJCS["WGS 84 / Pseudo-Mercator",GEOGCS["Popular Visualisation
CRS",DATUM["D_Popular_Visualisation_Datum",SPHEROID["Popular_Visualisation_Sphere",6378137,0]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Mercator"],PARAMETER["central_meridian",0],PARAMETER["scale_factor",1],PARAMETER["false_easting",0],PARAMETER["false_northing",0],UNIT["Meter",1]]
unfortunately this proj is not supported by my framework so I'm
trying to convert it to a standard WGS84 proj : gdalwarp -t_srs
WGS84
but I get the following error : ERROR6 : No translation for Mercator
to PROJ.4 format is known
any idea of what it wrong ?
You can explicitly give the source and target CRS with
-s_srs EPSG:3857 t_srs EPSG:4326
