Why would you want to generate point in the SPatial Portal? We had a number of users ask us if it was possible to get an average of environmental conditions within a given area. We developed this tool to generate points on a regular (of a user defined sized) grid within a user-defined area. Simple. What the tool produces is a new point layer that you can do with as you wish, but mostly we suspect useful for sampling layers?
