ID Generator

Use it to number parcels, boundary points, or survey marks in a consistent scheme.

• The identifier is assembled as Prefix + zero-padded number + Suffix. For example, a start of 1, a Pad Width of 3, a prefix of P-, and no suffix produces P-001, P-002, P-003.
• Pad Width is the reason to use this tool rather than a plain counter. Zero padding makes identifiers sort correctly as text: without it, 10 sorts before 2. Set the width to accommodate the largest number you expect — a width of 3 runs out at 999.
• Step allows gaps in the sequence. A step of 10 yields 10, 20, 30, leaving room for later insertions.
• Use selected features only limits numbering to the current selection. This is how a subset is renumbered without disturbing the rest — but note that the sequence restarts from Start for the selection, so check that the numbers it produces do not collide with existing ones.
• The numbering order follows the layer's feature order. If the identifiers must run in a particular geographic sequence, sort or renumber accordingly — the tool does not order features spatially.
• Existing values in the target field are replaced. Confirm the field is the right one before generating, and consider running Duplicate Finder afterwards to verify uniqueness.

1. Create or choose the target field. A text field is required if you use a prefix, suffix, or padding.
2. On the KGA Toolbox tab, in the Data Management group, open the VectorIQ menu, point to Manage, and click ID Generator.
3. Set Target Layer and Target Field.
4. Set Start and Step.
5. Set Pad Width wide enough for the largest number you expect.
6. Type a Prefix and Suffix if the scheme calls for them.
7. Click Generate IDs, then Close.
8. Run Duplicate Finder to confirm the identifiers are unique.

Requires an active KGA Toolbox license. The tool validates the license before running.
