Processing coverage data arrays with Python and Numpy

The following Python program reads signal strength indexed by latitude and longitude from a text file and puts the data into a Numpy array with axis 0 = latitude index and axis 1 = longitude index as explained in the IEEE Broadcast Technology magazine. Variables are set from a "study" file, described later.
