I pulled this (or close to it) out of oracles MDSYS.CS_SRS table for its
8307 SRID:
GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID ["WGS
84",6378137.000000,298.257224]], PRIMEM["Greenwich",0.000000
],UNIT["Degree",0.01745329251994330]]
If I put a line like:
8307=GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID ["WGS
84",6378137.000000,298.257224]], PRIMEM["Greenwich",0.000000
],UNIT["Degree",0.01745329251994330]]
In epsg.properties and rebuild gt2-epsg.jar would anything change, or am
I way off?
