[gdal-dev] Using a specific earth model

[Andrea Battisti]

Hi list!


I am testing a geotiff file which is in the following coordinate system
(from gdalinfo...):


Coordinate System is:
PROJCS["SIN         E019",
    GEOGCS["unnamed",
        DATUM["unknown",
            SPHEROID["unretrievable - using WGS84",6378137,298.257223563]],
        PRIMEM["Greenwich",0],
        UNIT["degree",0.0174532925199433]],
    PROJECTION["Sinusoidal"],
    PARAMETER["longitude_of_center",-82],
    PARAMETER["false_easting",0],
    PARAMETER["false_northing",0],
    UNIT["metre",1,
        AUTHORITY["EPSG","9001"]]]



The earth model used in the "SIN E019" should be an ideal sphere with
radius (m): 6370997, but it is not recognized and the WGS84 is used instead.
This leads to unwanted offsets on the projected image.

Is there a way to tell GDAL to use a specific model when it encounters a
specific coordinate system?



Thanks in advance!
