I know this question isn't exactly related to GDAL but I thought someone on the list might be able to answer this question.
So, I have a shape file that has the following spatial reference: PROJCS["Orthographic",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["W GS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017 453292519943295]],PROJECTION["Orthographic"],PARAMETER["Latitude_Of_Center ",40],PARAMETER["Longitude_Of_Center",-75],PARAMETER["false_easting",0],PA RAMETER["false_northing",0],UNIT["User Defined",1]] It was generated using OGR. I want to insert it into postgres / postgis but there is no direct match for the wkt or proj4 definition in the spatial_ref_sys table. So, I go to insert it into the table but the question arises, what SRID do I use? Do I just fudge a random one with a high enough value that I hope it won't conflict with some other SRID in the future, or do I create a table based off of the heterogeneous list of SRIDs at spatialreference.org and insert from that? I would like to do the later but that will be a pain unless someone has a put together a batch insert sql file for all the projections on spatialreference.org. Still, there is always the possibility that I may run into one that isn't defined and I will have to fudge my own number anyway. Question: What is the best way to handle this? I wish the spatial_ref_sys table came with all the ESRI and other SRID definitions. Suggestions are much appreciated! Best regards, Martin
