[OpenLayers-Users] RE: Google Terrian map does not align with geometry

[Nicholas Efremov-Kendall]

Hi JK,

The googles layers actually have different zoom levels, sometimes going to
hybrid goes to 21, physical goes to 22 and such. Look up the maxzoom for the
terrain layer, that might fix your problem.
