TRANSCO Process

To access this process:

Enter "TRANSCO" into the Command Line and press <ENTER>.
Display the Find Command screen, locate TRANSCO and click Run.

See this process in the Command Table.

Process Overview

Transform coordinates from one coordinate system to another. This is similar to the transform-coordinates command but instead works on data files, not loaded data objects.

Before coordinate transformation is performed, the input file and parameters are checked, and if the transformation cannot be completed with the specified inputs, a message displays indicating failure.

Source and target Well Known Transformation (WKT) codes are entered via the command line (or as inputs in a macro) after initial process execution.

These codes are listed on the transform-coordinates command screen and TRANSCO process references must match these codes precisely. For example, "EPSG:8321" is fine but "8321" or "EPSG 8321" will cause the process to abort.

Example

!START TRAN1

# - Use !LOCDBOFF to look for files outside the local folder

# - Use local files by deleting the next line or use !LOCDBON
