Re: [mapserver-users] Projection values of mapfile
Hello, If you are using a recent version of PROJ.4, you should be able to use epsg:3857 for Web Mercator. MapServer can reproject your data on-the-fly if you also have projection blocks in your layer definitions to say what projection the data are (i.e. epsg:4326). This will slow down the map draws somewhat, so if you are planning to always display this map in Web Mercator, it's a good idea to reproject your shapefiles. ... oh, it looks like Jeff beat me to it :) Christy On 11/05/2012 11:06 PM, Forest wrote: Hello everyone, I've been using shp2img tools to generate tile image by mapfile.
