Can anyone advise a hugely non-math-skilled MapInfo user on a formula to solve a problem? I have a group of settlements in a valley, of different sizes. The mountains surrounding the valley are mapped in their own layer. I want to be able to show the territory theoretically owned or dominated by each settlement, based on its area- big settlements own big territory- excluding the mountains. I tried a Voronoi diagram, using Vertical Mapper, but could only get a funny little diagram with equal size areas for each settlement. Buffering gave relative sizes in multiples of units nominated by MapInfo, miles, kilometres, chains etc, but only as a circle radiating from the location point of the settlement. My end result should be a pattern of ellipses radiating out from each settlement, abutting the boundary of each neighbouring settlement, but skirting the mountains. Any thoughts?
