This should be simple. I am using "transformer" to change KML files to shapefiles. My GPS golf course sprayer uses the shp file to determine where to spray and where not to. It works fine and allows the sprayer to read the Shp file and only spray within the polygon. How do I make a similar shp file that only allows spraying to be done outside of the boundary? The shp file is in 2D. Here is an example. One day I may wish to spray only the fairways. The next day I may wish to spray the rough outside of the fairways and not have any product sprayed on the Fairway. Hopefully there is a golfer, ERSI expert out there who can make sense of this question
