Hi Peter! That is brilliant. It never occurred to me that a target object could be used here, and it's certainly not mentioned in the on-line help. However, it was precisely what I was looking for, and I could use a slightly expanded hull object as target to produce quite another voronoi image of my point cloud.

Re: [MI-L] voronoi polgon I'm not sure if this is know by all, but you can actually control the area that the voronoi regions should cover, simply by selecting a region object and setting this object as the target area. This will tell MapInfo to extend the voronoi regions to the borders of the target area. Nice, eh ?

Re: [MI-L] voronoi polgon Hi All! That figures. The low resolution of your point table probably affects the voronoi code, when compared to close-up measurements. I have noted that the function creates polygons that stretch to the edge of the MBR for the point cloud for points at the perimeter of the cloud. A useful extension to the tool would be the option to use a 'hull' polygon to limit the size of such 'edge' polygons.
