Dear List I have two tables, each consisting of several thousand polygons - one of "hard" intertidal vegetation and the other of "soft" intertidal vegetation and sediments. I have another table of bird count zones. I would like to know if it is possible to use SQL to find out the precise hectarage (not including overlaps of poygons across the bird count zones) of the hard and soft vegetation within each bird-count zone.
So far I have tended to use the Cookie Cutter to make new tables - to make sure that there is no overlap (and therefore incorrect areal coverages). However, I have a lot of bird count zones and so would rather not have to do individual hard and soft vege tables for each zone. A new but accurate method would therefore be gratefully received. Will sum Best wishes Jacqui Foskett (GIS Officer, Chichester Harbour Conservancy) _______________________________________________________________________ List hosting provided by Directions Magazine | www.directionsmag.com | To unsubscribe, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MapInfo-L" in the message body.
