Malcolm just about to reply when martin stepped in with teh answer.. the only extra point i'd add is >>>
check that mapinfo is 'working ' in the projection of your grid ie in the mapbasic window type set coordsys table your_grid_table_namehere bear in mind that Martins solution returns values from minimum bounding rectangle for the grid object. if you have bent/ skewed or 'edited' the grid, the values of the grid corners may not correllate exactly with the the MBR... regards r -----Original Message----- From: Norman, Malcolm [mailto:[EMAIL PROTECTED] Sent: 09 January 2004 09:21 To: [EMAIL PROTECTED] Subject: MI-L extracting grid coordinates Hi, can some one tell me how I can extract the four corner x/y coords for regions created using MapInfo's Grid maker. I have been trying to do this through the update column routine in MapInfo, but am beginning the think that I might need to write a bit of MapBasic code instead We need the coord so that raster images can be registered in another web based application.
