Which Mercator projection does Modest Maps use?
Trying to match shapefiles. Modest maps has two easily-accessible maps projections in the calculator, linear and Mercator. Is that world Mercator, web Mercator, some kind of transverse mercator, etc.? Specifically, i'm trying to look up the projection id code. Thanks!

Inappropriate?The same as Google Maps, Virtual Earth etc: web Mercator I think. Using proj definitions to match up shapefiles, we specify the following target projection:
+proj=merc +datum=WGS84 +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs -tl -r
Hope that helps!
I’m happy

Inappropriate?awesome, i think answers it. I'm trying to match the projection with the right projection code. for ESRI, the id for wgs 1984 Web Mercator projection is 102113. not sure if there's an EPSG equivalent
I’m thankful
