I am mapping golf courses for the software package of TGC2019 for simulation purposes.  Just trying to map the courses in the area.

When I use lidar files to underlay the openstreetmap data, it creates the layout of the course with the proper elevations, along with green and fairway.  I am using opensource software that was created to marry the lidar and map data called chad's tool.  I have updated to the latest version of the tool.  I have watched many videos of other people that use the same software, and overlap fairway and greens all the time.

I am pretty new to GIS systems, and don't know exactly how mapping a golf course messes with any other data in the maps.  I guess once i map a course, I no longer need the data, so I could delete out the course data if it causes problems.  Just nice if someone else wants to use it for the same thing.

I noticed that someone else is editing another course in the area, and is doing it the way that you are talking about with mulipolygons.  I want to create the course in my software, but don't want to delete their data to input my own.

What software are people using to import the multipolygon fairways/greens that you are talking about?  Just curious if other software pulls the data in differently.
