So I want to be able to do the following:
- Click on a map to create a point.
- Then using my tracts file that has my data I want it to start to systematically start selecting traces based on the following:
- Start with the closest tract.
- Then select tracts one by one (always going to the next non selected tract) summing up the [market share] column until Marketshare is > 70%
- Make sure it does not have any holes in it.
How would someone get started doing this. Some of you may recogonize I am looking at creating some trade areas. What geoprocessing tools might be helpful in accomplishing this?
