DATA PREPARATION

            Idrisi data would be ideal to work with, since I will be using
            Idrisi v3.2 to do the analysis for Stan.  But Stan was provided
            with data for Arcview.

             I was able to convert the shape files from Arcview to Idrisi using
             the ShapeIDR (Import/Export shape files) command under the
            Help - Arcview/Arcinfo Quick View menu.  Import - Arcidris
            works as well

            The files are in vector format now and need to be converted over
            to raster.  This is done using the Vector/Raster Conversion
            commands in Idrisi.

            After looking at an extensive topographic map of the area it is
            apparent that there is not enough information to do a proper
            analysis and meet the criteria that Stan provided.  I had to add
            some data and make a few adjustments before the data would
            be ready for manipulation.

            The U.S. Military, the Navy in particular has a lot of property in
            San Diego, Mirimar Naval Air station(Top Gun) is one of three
            Naval air stations in the area, there are also a small number of
            Naval reserves.  I had to digitize all their lands into a vector
            layer then convert to raster.
 

            I also had to digitize the points Sea World and WORK and
            convert them over to raster as well.  The water layer had to
            be divided up into lakes and harbours and that was done using
            Reclass, which was also used to convert the layers to boolean
            images so that the MCE (multiple criteria evaluation) could
            take place.
