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.<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Courier New"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Courier New"'>Question: What is the best way to handle this?
