Convert 5 miles (half your square side) in your table XY units. If your table is in degrees, change to a pertinent projection. If the projection unit is meters, that value will be something like 8045
In the MBW write and run Update your_table set obj=mbr(createline(centroidx(obj)-8045, centroidY(obj)-8045, centroidX(obj)+8045, centroidY(obj)+8045)) Jacques Paris e-mail [EMAIL PROTECTED] MapBasic-MapInfo support http://www.paris-pc-gis.com -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Kent Treichel Sent: January 10, 2002 10:48 To: Mapinfo List Subject: MI-L Creating square areas around centroids I have a table of centroids and am looking for a way to turn each centroid into a square region, approximately 10 miles aside, for the purposes of thematically mapping it.
