I use the Create Fishnet tool (specifically the Create Label Points function) to create a plot grid of regular spacing for forest sampling. Currently, there is no option in the tool to limit the Create Fishnet template extent to an intersect with polygons in a feature class. Adding this function would increase user efficiency, as the current protocol is 1. Create Fishnet over the extent of the feature class. 2. Select label points by location, intersecting (-5m for GPS error) with the feature class, 3. Switch the selection, 4. Delete out the unwanted label points. This protocol works fine with small Fishnets, but when the number of unwanted label points approaches 4,000,000, the creation, selection, and deletion of unwanted label points, plus the saving of this new label point feature really bogs the process down. It's a lot of time to spend on superfluous points.
