Transform Clause - MapInfo_Pro - 2023

When you have MIF files with coordinates stored with respect to the northwest quadrant (quadrant 2), you can transform them to the northeast quadrant (quadrant 1) with a transform clause.

The transform clause has the following syntax:

TRANSFORM Xmultiplier, Ymultiplier, Xdisplacement, Ydisplacement

To transform quadrant 2 data into quadrant 1 data, use the following transform clause:

TRANSFORM -1,0,0,0

The zeroes instruct MapInfo Pro to ignore that parameter.

When you have an application which creates MIF files in quadrant 2, you can:

• Add the TRANSFORM clause to the MIF files
• Change the application so that it creates coordinates in quadrant 1
• Change the application so that it adds a TRANSFORM clause to the MIF files
