[Geoserver-users] reprojection error

Giuseppe_Falcone1 · January 26, 2015, 9:12am

Hi all,

I have a problem with geoserver raster reprojection.

I have a raster layer derived from an image mosaic store. In layer configuration, in the native srs field appears ‘UNKNOWN’ and label ‘TMBOAGA2’ on the right with these values:

PROJCS[“TMBOAGA2”,
GEOGCS[“MONTE MARIO”,
DATUM[“MONTEMAR”,
SPHEROID[“INT24”, 6378388.0, 297.0]],
PRIMEM[“Greenwich”, 0.0],
UNIT[“degree”, 0.017453292519943295],
AXIS[“Longitude”, EAST],
AXIS[“Latitude”, NORTH]],
PROJECTION[“Transverse_Mercator”],
PARAMETER[“central_meridian”, 15.0],
PARAMETER[“latitude_of_origin”, 0.0],
PARAMETER[“scale_factor”, 0.9996],
PARAMETER[“false_easting”, 2520000.0],
PARAMETER[“false_northing”, 0.0],
UNIT[“m”, 1.0],
AXIS[“x”, EAST],
AXIS[“y”, NORTH]]

Any reference system I set as declared srs (EPSG:32633, EPSG:26592), and any selection I set in srs handling field, the layer is drawn with a vertical displacement of about 150 meters down.

Any idea about this?

Thanks a lot.

Giuseppe

Ciao Giuseppe,

Did you try with EPSG:3004 as declared SRS?

Cheers,

Thanks for the quick response.

The behaviour is the same.
The geoserver version is 2.6.1

I see these metadata of a single tile with an other software:

150 meters is an entity compatible with the datum shift error.

You can try to override the EPSG:3004 SRS with the following values:

3004=PROJCS[“Monte Mario / Italy zone 2”,GEOGCS[“Monte Mario”,DATUM[“Monte_Mario”,SPHEROID[“International 1924”,6378388,297,AUTHORITY[“EPSG”,“7022”]],TOWGS84[-168.6, -34, -38.6, -0.374, -0.679, -1.379, -
9.48],AUTHORITY[“EPSG”,“6265”]],PRIMEM[“Greenwich”,0,AUTHORITY[“EPSG”,“8901”]],UNIT[“degree”,0.01745329251994328,AUTHORITY[“EPSG”,“9122”]],AUTHORITY[“EPSG”,“4265”]],UNIT[“metre”,1,AUTHORITY[“EPSG”,“9001”]],PROJECTION[“Transverse_Mercator”],PARAMETER[“latitude_of_origin”,0],PARAMETER[“central_meridian”,15],PARAMETER[“scale_factor”,0.9996],PARAMETER[“false_easting”,2520000],PARAMETER[“false_northing”,0],AUTHORITY[“EPSG”,“3004”],AXIS[“X”,EAST],AXIS[“Y”,NORTH]]

You need to had the previous string in the user_projections/epsg_overrides.properties file inside the GeoServer data dir

Also this setting has failed.
I created epsg_overrides.properties in user_projections and restarted tomcat.
Also I have tried with ‘force declared’ and ‘reproject native to declared’ in SRS handling (declared srs is 3004)
