Hi Steven, I had the same problems, my data were in EPSG:23030 but when I wanted to overlay my WMS in Google Earth, even If I'd included EPSG:4326 in the wms_srs list, It showed a difference between my map and Google. So, first of all, you must include the 4326 in your wms_srs list (in the header and in the layers), then you must set EPSG:4326 as your projection object in the header, leaving the layers projections as 31300, and then you must look at the epsg file in the PROJ library (\\ms4w\proj\nad), because probably your EPSG code (31300) asn't all the parameters needed to reproject correctly the data...
Look something like +towgs84, and try to find some parameter that help MapServer to reproject better the data...like this you won't have to reproject your original data Regards gisaalter wrote: > > Hi list, > > I have some data in PostGIS I wish to overlay in Google Maps using WMS > I'm using the same data in a mapserver application, where EPSG code > 31300 is used. > Now for overlay in Google Maps, 4326 is required. > I have made a copy of my map-file and specified 4326 as projection > system.Yet, non of my data is showing up. > > Do I need to reproject my data for this use ?
