What you can do with it

Typical work that data of this type supports.

  1. 01

    No-gauge areas

    Monitor places with no ground stations.

    Because it has: satellite altimetry

  2. 02

    Long records

    Use consistent records going back decades.

  3. 03

    Storage tracking

    Follow storage and releases through the season.

    Because it has: lake water level

Where AI adds value

Ideas for machine learning and AI agents built on this kind of data.

  1. 01

    Segmentation

    Map water, crops and land use pixel by pixel with deep learning.

  2. 02

    Data fusion

    Blend satellite and ground data into one better estimate.

  3. 03

    Storage from space

    Estimate volume from satellite water area and altimetry.
