I need to project rasters to serve through geoserver to overlay google
maps in OpenLayers.
I'm been using gdalwarp to project rasters to web mercator, here's an
example:
gdalwarp -s_srs "+proj=tmerc +lat_0=0 +lon_0=27 +k=1 +x_0=0
+y_0=0 +ellps=WGS84 +datum=WGS84 +units=m +no_defs" -t_srs
'EPSG:900913' -r near -multi -dstnodata "0 0 0" -dstnodata "0 0
0" -dstalpha -co COMPRESS="DEFLATE" -co "TILED=YES" -of GTiff
2627BB_05_1117_RGB_RECT.TIF /tmp/test900913.tif
The problem is, whatever I use for -t_srs (EPSG:900913, EPSG:3857 or the
proj4 string), each one generates a different WKT header in the output
geotiff and none of them is recognised as '900913' by GeoServer since
GeoServer uses a non-standard WKT definition for 900913.
Overriding the projection in GeoServer by declaring 900913 doesn't work
either.
Surely this is a common requirement? I'd be grateful for any help.
(geoserver 2.0.2)
thanks
Gavin
