Summary:
CoordinateExtractor.mbx - A MapBasic program to extract coordinates from a table.

Question:
Is there a MapBasic program that will automatically update columns with X and Y coordinates in a table’s native projection?

Answer:
The CoordinateExtractor.mbx will add two columns to a selected table and update the columns with X and Y coordinate values in the table’s native projection as opposed to the default projection of Longitude/Latitude.

For example, if a table is in UTM Zone 16, the coordinates will be in UTM values. If a table is in the default Longitude/Latitude projection, the coordinates will be in decimal degrees.

For objects other than points (such as polygons, lines), the X and Y coordinates will represent CentroidX and CentroidY values of the object.

To install and run the program:

1. Un-attach the MBX and place it inside the MapInfo\Professional\Tools directory.

2. Inside of MapInfo, choose File>Run MapBasic Program and select the CoordinateExtractor.mbx.

3. Go to the Tools menu and CoordinateExtractor should be listed. Start the program from there.
