[Qgis-user] Custom CRS: from WKT to PROJ.4

[Jakob Petersen]

I’m using QGIS to produce a .svg layer to be imported into Adobe
Illustrator and added to an existing map project. Apparently, a EPSG
projection was not used and the following WKT parameters have been provided:


PROJCS["Orthographic, meter (Pakistan)",GEOGCS["WGS
84",DATUM["wgs_1984",SPHEROID["WGS
1984",6378137,298.257223563],TOWGS84[0,0,0,0,0,0,0],AUTHORITY["EPSG","6326"]],PRIMEM["Greenwich",0],UNIT["degree",0.0174532925199433],AUTHORITY["EPSG","4326"]],PROJECTION["Orthographic"],PARAMETER["false_easting",0],PARAMETER["false_northing",0],PARAMETER["latitude_of_center",30.292],PARAMETER["longitude_of_center",69.178],UNIT["Meter",1,AUTHORITY["EPSG","9001"]]]


To write the PROJ.4 for the QGIS customised CRS I have used the parameters
(+proj +lat_0 +lon_0 +x_0 +y_0) listed in
http://www.remotesensing.org/geotiff/proj_list/orthographic.html

The projection comes close, but I wonder if more parameters can be used
than the ones listed by remotesensing.org?


Many thanks,   Jakob
