Hi,
I want to overlay a WMS layer on google base map (Google Physical).
The image that I have is a raster data and am using MapServer to show
the image.
The data is in Transverse Mercator projection.
I'm able to get the image when I hit the mapserver url in the browser,
provided i give the extent in meters for that particular country but
using OL, i get only a blank image.
The projection is 4326 in the map file.
OL code:
var twms1 = new OpenLayers.Layer.WMS(
"Land_use_cover_from_SPOT","http://localhost/cgi-bin/mapserv?",
{ map: "Land_use_cover_from_SPOT.map",
units: "m",
transparent: 'true', layers:"Land_use_cover_from_SPOT",
format: 'image/png',
maxExtent: new
OpenLayers.Bounds(1610000,6568500,1638000,6594000),
//maxExtent: new OpenLayers.Bounds(60,0,100,40)
//maxResolution: 156543.0339,
projection:"EPSG:4326",reproject:false
},{singleTile: 'true'});
map.addLayers([twms1]);
Does some one know how to project transverse mercator on Google map??
Please help.
Thanks & regards,
Subha
