Hi,<br> Â I have a shapefile which consists of a grid (polygons), each of which is 1 quarter degree in extent. I would like to create a second coverage where each polygon is again subdivided into smaller polygons, each being 5 degrees by 5 degrees in extent. Essentially each degree square would consist of 144 polygons.<br> Â Appreciate any suggestions, thanks, <br><br>Paddy
