Write-back and viewer editing

Write-back lets viewers — not just authors — contribute to the data behind a map. It turns a map from something you only read into something people can update: capturing a new location, correcting an attribute, or adding a note against an existing feature.

What viewers can do

• Add a record at a location — click the map to drop a new point and fill in its details.
• Add a record attached to a feature — add child records against an existing feature (for example, an inspection against a site).
• Edit a feature's values — update fields of a selected feature through editable text boxes.

How it's built

Write-back is assembled from visuals you place on the map:

• An Add button that arms a "capture the next click" session,
• A Location visual that shows the captured coordinates,
• Editable text boxes inside a write-back-enabled panel, and
• Save and Cancel buttons.

Where the data goes

Edits are written to either the map's own annotations store or a layer file (GeoJSON or CSV) in your OneLake, with key columns to match records and audit fields to record changes.

Next steps

• Panels, text & images — the visuals write-back uses.
• Security & permissions — the write access it needs.
