Ogun SDI & LULC Mapping

Background

Ogun State needed a centralized, modern geospatial platform — plus a statewide Land Use/Land Cover (LULC) mapping deliverable on top of it — and a system its own team could run, extend and trust. Delivered by Sivan Design under the Ogun State Economic Transformation Project (OGSTEP) for the Ogun State Government, Nigeria, I served as GIS Project Manager: technical design, leading the development team, and the training that handed the platform to the Ogun SDI team.

Methodology

  • Directed the design and deployment of an open-source SDI on GeoNode, GeoServer and PostGIS, hosted on the state's own VMs with OGC-compliant web services (WMS/WFS/WCS).
  • Directed design of the Geom Tool — an in-house app that lets surveyors upload survey data and semi-automatically generate cadastral parcel geometry, replacing slow manual digitization with an auditable workflow.
  • Led design of the cadastral layers, a statewide Unique Parcel Identifier (UPI) framework, and a bi-directional integration between the SDI and OLARMS (the state's land-administration system).
  • Directed the statewide LULC classification, combining Sentinel-2 and high-resolution imagery with field ground control points and temporal change analysis.
  • Designed and delivered hands-on training — GIS/QGIS basics, block-drawing, and Administrator Training that handed clear ongoing roles to the four-person Ogun SDI team.
