Editing Layer Data

There are two approaches to modifying existing layer data: using the Edit Map interface or the spreadsheet export/import workflow.

Method 1: Using the Edit Map (Annotate)

This is the quickest way to update individual features:

  1. From the Admin Console, click the "annotate" link for the layer you want to edit
  2. This opens the Edit Map interface for that layer
  3. Draw the updated geometry (point, line, or polygon depending on the layer type)
  4. Fill in the property values in the control fields - use the same identifying values as the feature you're replacing
  5. Click Save to submit

The new feature will be processed as an update to the existing data.

Best for: Quick updates to individual features, geometry corrections, adding new features

Method 2: Using Spreadsheet Export/Import

For bulk edits or when you need to modify many features at once:

  1. Export the layer data
  2. From the Admin Console, find the layer in the "Layers" section

  3. Click the "Export to Sheet" link to export to Google Sheets

  4. Edit the data

  5. Modify property values directly in the spreadsheet cells
  6. Add new rows for new features

  7. Delete rows to remove features

  8. Re-import the data

  9. Use the "Import from Sheet" function in the Admin Console

Best for: Bulk text changes, fixing typos across many features, deleting multiple features

Method 3: Deleting Features with the Edit Map

You can delete features directly on the map by drawing a polygon around them:

  1. From the Admin Console, click the "edit" link for the layer
  2. Draw a polygon on the map around the feature(s) you want to remove
  3. A Delete button will appear in the edit panel — click it
  4. Confirm the deletion when prompted

All features whose geometry intersects the polygon will be removed. This works well for removing a single misplaced point or a cluster of features in a specific area.

Note: Deletions cannot be undone through the edit interface. If you need to recover deleted features, roll back to a previous published version.

Bulk deletion: If you need to remove many features across the layer, the spreadsheet method (export, delete rows, re-import) is more efficient.
