I'm creating a GeoMoose application that will use the various Google tile layers as backgrounds. (I originally created a basic app in my local state plane projection but then realized that the Google-like backgrounds are critical.) I've downloaded the Web Mercator demo and am looking at <a href="http://geomoose.org/howto/commercial_layers.html">http://geomoose.org/howto/commercial_layers.html</a> for guidance. As I go through this, a few quick questions:<br>
<br>1) Should I use EPSG:3857, EPSG:3785 or EPSG:900913? Or does it matter as long as Proj4 supports it and there's a corresponding file in proj4js\lib\defs <br><br>2) In the mapbook file, should all the data sources (nearly all of WMS type) have the same projection attribute, such as projection="EPSG:3857"? <br>
<br>3) Just to confirm, my raw data files do not need to be in the "web mercator" projection, only the MAP Projection and Extent parameters in the map files, correct?<br><br><br>- John<br><br clear="all">***********************************<br>
