Creating a text file to generate displacement links
Link files are text files that contain source and destination coordinates that define an adjustment. Spatial adjustment supports tab-delimited link files that contain either four or five columns. A four-column link file consists of two pairs of source and destination coordinate values. A five-column link file consists of an ID column (string or numeric) that precedes two pairs of source and destination coordinate values.
- Open an ASCII text editing program, such as Microsoft Notepad.
- Type the link ID and the coordinates using the format below. You don't need to type the headers.
- Save the file to disk.
- Start ArcMap and open the link file.
<ID> <from_x> <from_y> <to_x> <to_y>
Each link should be on a separate line, and the delimiter should be either a space or a tab. The <ID> column is optional but should precede the coordinates if used.
