All,<div><br></div><div>Apologies if this has been asked before and cross posting. Well, in dire situation.</div><div><br></div><div>I'm working on a project in Malaysia and the ran into major road block because of the local projection. All existing datasets are in older Cassini projection. They have 9 state level Cassini projection for cadastal work and they have different origin. It uses Everest 1830 Modified for spheroid.</div>
<div><br></div><div>They are moving to their new projection called GDM2000 and they have EPSG entries. But the older cassini dont have EPSG entries. this puts me in real fix.</div><div><br></div><div>ArcGIS has the projection parameters for cassini and I dont find any details in spatialreferece or EPSG.org.</div>
<div><br></div><div>My work involves GeoServer and PostGIS. Can you plesae guide and help me with this? How do I put a custom projection and how do I work on a projection that dont have EPSG? Since we work lot on EPSG with GeoServer and PostGIS, how can we support the non standard one.</div>
<div><br></div><div>This is the CRS parameters;</div><div><br></div><div>PROJCS["Malaysia_Cassini_Kelantan",GEOGCS["GCS_Kertau",DATUM["D_Kertau",SPHEROID["Everest_1830_Modified",6377304.063,300.8017]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Cassini"],PARAMETER["False_Easting",0],PARAMETER["False_Northing",0],PARAMETER["Central_Meridian",102.8952083],PARAMETER["Scale_Factor",1],PARAMETER["Latitude_Of_Origin",4.946141667],UNIT["Meter",1]]</div>
<div><br></div><div>any guru out there help me?</div><div><br></div><div>another question, can this be reprojected to WGS84 using on the fly reprojection in GeoServer and PostGIS?</div><div><br></div><div>Thanks a lot</div>
