Second Data Collection Run - HDOP 0.81 to 7.95

This is a GIS plot of some 3785 readings and slightly colour coded to show the HDOP.  Dark Green is low and light Green is a high HDOP value.  I also show where the actual GPS is located and where the everage of the reads says thinks it was.  The light blob on the right is my house, there is an empty block, then my neighbours house.  The average GPS reading is approximatly 37m from where the actual GPS sits.  I think the error is a result of it sitting in a West facing window.  North is up.
