Adding the geostationary projection.
|Reported by:||martin.raspaud||Owned by:||davidhassell|
There seems to be a need from the weather satellite people to add the "geos" projection to the list of projections in the CF metadata.
"geos" stands for geostationary. The projection is described in detail in the "CGMS 03, LRIT/HRIT Global specification" (Eumetsat) document. (see here also: http://remotesensing.org/geotiff/proj_list/geos.html )
A possible text for this projection is:
grid_mapping_name = geos
The x (abscissa) and y (ordinate) rectangular coordinates are
identified by the standard_name attribute value projection_x_coordinate and projection_y_coordinate respectively. Notes:
Notes on using the PROJ.4 software packages for computing the
mapping may be found at http://www.remotesensing.org/geotiff/proj_list/geos.html . These notes assume the point of observation is directly over the equator. The projection coordinates in this projection are directly related to the scanning angle of the satellite instrument.
