Point Renumbering or Replacement

It's possible to renumber existing coordfile points and new points being added to a coordfile.

Renumbering Existing Coordfile Points

To renumber current coordfile points on an individual basis, see To Renumber a Point Record in § Point Records.

To delete, renumber, or edit a group of existing coordfile points, see § Bulk Point Editing.

Renumbering New Points

When adding batches of new points to a coordfile — such as in Import Ascii, Field Data Process, or Map Traverse Adjustment — what if some of your incoming points are not numbered the way you wish them to be or already exist in the coordfile? You can instruct Copan what to do before clicking Import or Save points.

To automatically renumber every incoming point

Check Renumber all new points.

When incoming points have numbers matching coordfile points

Check Always replace existing point if you know that new point values should replace existing ones.
Check Never replace existing point if you know that new points should be ignored and existing ones should remain unchanged.
Check Ask before replacing point in order to decide what to do on a point-by-point basis.
Check Renumber the new point if you know that new points should be renumbered and existing ones should remain unchanged.

Rules for renumbering

You also have a selection of possible rules for the new number:

Check Increase by . . . for each new point number to be increased by a constant value.
Check Use next available for each new point number to be replaced by the next unused point number.
Check Use highest + 1 for the new point numbers to begin after the current highest point.
Check Start at . . . for the new point numbers to begin at a specified value.

If you want each new point to remember what its original number was before being renumbered, check Record old # in Name field.
