Two deployments

Farms in Kura, and BizTerrain in Tarauni.

  1. 3,000+farm fields mapped in Kura, Kano State, each with 20+ attributes

Deployment figure from LINX’s Kura model (2018). BizTerrain business figures are published once the dataset is checked.

Two deployments

What the maps showed.

  1. Kura · Kano State · 2018

    3,000+ farm fields mapped, each with 20+ attributes. Community town halls and public display of records verified the data and resolved disputes, supporting farmland CofOs with the Kano State Government.

  2. Irrigation

    Thematic maps compared approved and actual crops, to explain water shortages in the irrigation scheme.

  3. Cattle routes

    Historical cattle routes were overlaid on farms, to study the causes of farmer–herder clashes.

  4. BizTerrain · Tarauni ward · 2019

    The same field tools profiled businesses in Tarauni ward for BizTerrain, LINX’s business-mapping portal, which maps informal businesses for registration and presumptive tax.

    CaptureAn offline Android app

    Captures farm boundaries, attributes and photos without a connection.

  2. 02
    CheckA spatial database

    With quality checks and duplicate detection.

  3. 03
    PublishWeb mapping and reports

    A web mapping platform on Leaflet and GeoServer, with a reporting module.

  4. 04
    TrainField-team training

    Training materials and sessions for field teams.
