Hi, I am new to openlayers and I have a pretty basic but fundamental question on how to handle different projections. I have a datasat that I want to serve through an openlayers webpage. The problem is that the data is stored in an irish Grid format: http://spatialreference.org/ref/epsg/29902/
I was hoping that changing the projection to EPSG:29902 would automagically fix everything but it ended up throwing an error: Uncaught TypeError: Cannot read property 'R' of undefined some further reading showed that only projections EPSG:4326 and EPSG:900913 came with openlayers: http://dev.openlayers.org/apidocs/files/OpenLayers/Projection-js.html I am now at the point where I am going to start using pro4js to convert my coordinates. So here are my current options: 1: convert the coordinate system of the basemap to the irish grid 2: take the inputs from the user in EPSG4326 and convert them to irish grid 3: convert the whole dataset to EPSG4326 I know there is no correct answer but is there a best practice when mixing grid systems? Any help would be greatly appreciated. -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Changing-projection-to-match-a-dataset-tp5229956.html Sent from the OpenLayers Users mailing list archive at Nabble.com. _______________________________________________ Users mailing list us...@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/openlayers-users
