Hi all,
I have to serve GeoTIFF rasters extracted by gdal from Geostationary satellite
hdf5 files. The images are provided in Geostationary projection (aka.
"full-disc", aka. "space-view").
This projection, supported by GeoTIFF
(http://www.remotesensing.org/geotiff/proj_list/geos.html) appears to be also
available as custom to GeoServer.
I followed http://spatialreference.org/ref/sr-org/81/geoserver/ which says:
# put this custom projection in the 'user_projections' file inside the
GEOSERVER_DATA_DIR
# You can further work with your projections via the web admin tool.
81=PROJCS["unnamed",GEOGCS["unnamed ellipse", DATUM["unknown",
SPHEROID["unnamed",6378137,298.257223563]], PRIMEM["Greenwich",0],
UNIT["degree",0.0174532925199433]], PROJECTION["Geostationary_Satellite"],
PARAMETER["central_meridian",0], PARAMETER["satellite_height",-0],
PARAMETER["false_easting",0], PARAMETER["false_northing",0]]
Nevertheless after reboot, GeoServer doesn't displays this projection in the
SRS list.
Of course I changed the values for "central_meridian" and "satellite_height"
according to my data, then added the projection a single line string in the
file /geoserver/data/user_projections/epsg.properties).
Moreover, EPSG provides 2 other valid orthographic projections
(EPSG:9839,9840), which are not listed in the SRS list of the GeoServer.
Did someone already successfully added Geostationary projection (or other
orthographic projection) to GeoServer to serve raster as WMS?
Many thanks,
Victor
