[OpenLayers-Users] Measure tool in 2.7 RC1

[Jennifer Strahan]

Hello,

Thanks for including the measuring tool!  I'm wondering if there are any 
guidelines for use that I should follow.  I added a Google map layer to 
the measure example and am finding some error with the measurements.  Is 
it possible that my map settings are wrong?

I measured Alamo Square in San Francisco and the area result is around 
92557 square meters (nearly 23 acres).  The actual measurement should be 
around 13 acres. 

My test map is here:

Any suggestions as to how I can adjust my settings to get the correct 
results?

Thanks,
Jennifer
