Harness Untapped
Ground-Truth Data

GeoAI needs historical data from space and from the ground, but the latter is lacking. While satellite imagery archives are easily accessible, ground-level imagery archives are largely locked in billions of smartphones. Unlocking this data requires trust:

• Trust between your organisation and the people on the ground you will reach to solve your ground-truth data gap problem.
• Trust between the people you will reach and their networks, so the number of people reached can grow exponentially.
• Trust between your organisation and askphotos.earth:
  • We are not interested in your data. askphotos.earth's workflow and open-source technology are designed so that we never see your ground-truth data.
  • We are interested in building the technology and the network to support organisations harnessing untapped ground-truth data. If you would like to receive updates, please subscribe to our newsletter.

The right prompt to the right crowd can quickly give you access to a large ground-truth dataset. Unlike a data collection campaign, which can take weeks or months, a data unlocking campaign can be completed within hours.

e.g. Photos of construction sites in Addis Ababa in January 2026

To privately prompt the crowd's phones, add the generated link to the form template below. When people click it, Google Photos opens with your prompt already searched, so they can select matching photos and share them back as an album link.

If you do not have access to the right crowd or need an managed solution, get in touch.

Once you receive the photo album links in your form responses or in the WhatsApp/Telegram groups, export them in CSV or TXT format and use the Ground-Truth Data (GTD) Generator to automatically generate spatial analysis-ready data.
