Hi,
I'm having some issues creating a custom SRID where the units of the spatial reference system are stored as radians in PostGIS.
We store our data in radians but is otherwise like EPSG:4326. In order to do transformation of the data I have been experimenting with creating a custom SRID. I have tried a multitude of strings.
I have downloaded the code for proj4 to see how it is using the params and I thought that this would work:
"+proj=longlat +ellps=WGS84 +towgs84=0,0,0,0,0,0,56295779.51308231 +no_defs "
"GEOGCS["WGS 84Rad",DATUM["WGS_1984Rad",SPHEROID["WGS 84",6378137,298.257223563,AUTHORITY["EPSG","7030"]],AUTHORITY["rb","6326"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["radian",1.0000000000000,AUTHORITY["EPSG","9101"]],AUTHORITY["rb","8307"]]"
but no joy.
any insight would be greatly appreciated, especially if you have actually implemented the same thing successfully.
Thank you,
Stacie
