[Geoserver-users] Cannot add Geostationary satellite as custom projection to the SRS list of GeoServer

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

This projection is not supported by GeoServer, we don't have the math for
it. It can be added,
would be less than a day work for someone familar with both proj and
geotools source code (port
over the math, develop tests, check against some data)

Hi Andrea,

It appears you formulated such a request 5 years ago (http://jira.codehaus.org/browse/GEOT-2933).

Do you know if someone followed it, or well if such an implementation is scheduled in the future?

Afaik this projection is common to remote sensing rasters (all geostationary satellite products are provided in this projection).

Thanks again,

Victor

It will happen the first time either someone decides to spend some Sunday
working on it, or when someone sponsors it.
So far, neither of the two has happened. Hard to tell when it will.
If you are interested in coding it yourself and donate the results back to
the community, I can give you pointers on what needs to be modified.

Cheers
