Map Overlays

The Overlay feature lets you enhance your Interactive Well Maps with additional spatial data. You can choose from:


  • Public Domain Overlays – Provided by the AFA, including field boundaries, license areas, and historical well locations.

  • Private User Overlays – Your own uploaded GeoJSON or Shapefiles, visible only to you and your organization.


This feature is ideal for development planning, field layout reviews, and advanced spatial analysis.

Using Public Domain Overlays - coming in 2.9.0

  1. Open the Map – Navigate to the Interactive Well Maps tool.

  2. Select Overlay Source – Choose from the list of available public overlays.

  3. Enable Overlay – Toggle the overlay on to display it alongside your well data.

Uploading Private Overlays - coming in 2.9.0

  2. Upload the Overlay

    • Click Add Overlay.

    • Select Upload File.

    • Browse and select your GeoJSON file.


  3. Name & Describe – Give your overlay a meaningful name and optional description.

  4. Save & View – Once uploaded, the overlay will be visible only to you (or your organization, if shared internally).

Managing Overlays

  • Toggle On/Off – Use the overlay list to control visibility.

  • Delete Private Overlays – Remove files you no longer need.

  • Reorder Layers – Change the drawing order so important overlays appear on top.

Example Use Cases
