[mapserver-users] Google Maps Tile overlay shift

[Varun saraf]

Hi,

For some time now, I have been using Mapserver with Tilecache and
Google maps to display census tract overlays to users. However, the
users complain that the overlay is not accurate if they zoom into the
map (say level 13 onwards). Is this a problem with the projection
scheme being used? I think my data is in epsg 4326 format and google
uses 900913 I think. I insrted this into the Proj 4 epsg file but
still the overlays are shifted by a bit. If anyone who has solved this
problem can direct me, it would be a great help.

BTW, I use ms4w for windows and the GtileOverlay method with tilecache.

Thanks,
Varun
