I am in the process of completing some Mobile Coverage plots using a Spectran Analyzer and GPS Logger. Please see the attached - is there some document that can help with identifying what is line represent? - the red, yellow and blue lines.
The red line indicates the maximum measurement value of the measured spectrum at this position
The yellow line is the average value
The blue line is the minimum measurement value.
There should be some controls on the left hand side of the Google Earth application where you can enable/disable those lines and waypoints including the actual values and frequencies.
