Hi Ian, Thanks for your help. I probably have enough information from everyones help today to create my own tabled automatically. I can then merge some maps into layers. But as you say there will probably be issues with the limit of files or size of bitmap data. This is still my final problem. Once I've created my million or so tables that I've automatically created, I now need to dynamically load the ones I need. It's going to be an interesing one to solve. Kind regards Tim Smith

The .tab can be created as follows (in MapBasic) open file tablename for output as #1 filetype "MIta" print #1, "!table" print #1, "!version 300" print #1, "!charset WindowsLatin1" print #1 print #1, "Definition Table" print #1, " File """ + filename + """" print #1, " Type ""RASTER"" " print #1, " (" + tle + "," + tln + ") (0,0) Label ""TopLeft"", " print #1, " (" + tre + "," + trn + ") (35000,0) Label""TopRight"", " print #1, " (" + ble + "," + bln + ") (0,35000) Label""BottomLeft"", " print #1, " (" + bre + "," + brn + ") (35000,35000) Label""BottomRight"" " print #1, " CoordSys Earth Projection 8, 79,""m"", -2, 49, 0.9996012717, 400000, -100000 Units ""m"" " close file #1 You will need to look in your first tab file for the correct values for the coords i.e. (0,35000) etc but as all of your areas are square is should be easy. I have used a Seamless table on about 100 tables of aerial photos and it works really well (I don't know what the limits are) Hope this helps, Ian Hull Greater Manchester Transportation Unit Salisbury House Granby Row Manchester M1 7AH Tel: 0161 455 2059 Fax: 0161 455 2071 E-mail: [EMAIL PROTECTED] Website: www.agma.gov.uk/transport.asp?id=3 ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
