Yes, look at the areaoverlap function. The best thing to do is to generate an SQL intersect query with the Mapbasic window open, selecting the fields you want in the output. Cancel the query (ESC). Then edit the query in the window. Add Areaoverlap(Tablea.obj,Tableb.obj) to the SQL and then you will have some data that you can work with.
Good luck Andy "John Nott" <[EMAIL PROTECTED]> 11/03/2005 15:02 To: <[email protected]> cc: Subject: MI- L Proportioning Areas of Overlap Hello All, Firstly thanks very much to everyone who responded to my plea yesterday when I was looking for help enclosing landline polygons. It was a great help and I sorted the problem. Hopefully I will get the same response this time. I have a polygon which overlaps with 3 polygons from a different layer. What I would like to do is to assign new attributes to the original polygon of what percentage of each other polygon is within the original one. So basically I need it to say. Polygon A overlaps Polygon X , Polygon Y and Polygon Z. 25% of Polygon X is within Polygon A, 70% of Polygon Y is within Polygon A ...... Is this possible? The desired outcome would be to add this data as an extra attribute field to the original polygon dataset. Thanks in advance for all your help. - John John Nott Consultant/GIS Analyst ROGER TYM & PARTNERS Fairfax House, 15 Fulwood Place, London, WC1V 6HU t 020 7831 2711 f 020 7831 7653 e [EMAIL PROTECTED] w www.tymconsult.com The information in this email is confidential.
