Field data associated with blackfly/vector-control monitoring along communities and the Ose River system around the Edo–Ondo border. The underlying study says the collected data are openly available through Figshare.

972 georeferenced observations across Port Harcourt, with latitude/longitude and an Urban Environmental Quality Index covering cleanliness, infrastructure, traffic, environment and aesthetics.
Institution: University of Port Harcourt.

Plant specimen records from Ahmadu Bello University, including taxonomy, collection information, locality and geographic information.

Georeferenced plant-occurrence data from the hill forests and Biological Garden around Obafemi Awolowo University, useful for vegetation, biodiversity and ecological mapping.

Bird observations across Nigeria, covering pentad/grid locations and dates, designed for mapping and spatio-temporal analysis. The current GBIF record was published/updated on 2 June 2026.

This is another useful coastal biodiversity dataset, focused on marine fish and shellfish records. The publisher is University of Lagos and the licence is explicitly CC BY 4.0

This one is particularly nice for GeoHubNG because it gives us Bayelsa-specific biodiversity data. The GBIF record identifies the University of Calabar as publisher and confirms CC BY 4.0.

A historical ecological and remote-sensing research dataset from the Olokemeji grassland site in Nigeria covering 1956–1964. The dataset contains ASCII time-series files with measurements of above-ground biomass, dead matter and net primary productivity, providing a rare long-term ecological record for Nigerian grassland research. Publisher: NASA.

A 10 m resolution geospatial raster dataset mapping the spatial distribution of cassava and maize fields across Oyo State, southwestern Nigeria, for 2022. Crop predictions were generated using fused Sentinel-1 SAR and Sentinel-2 optical imagery, supervised machine-learning classification and field-validated ground-truth observations. The package includes GeoTIFF crop-extent layers, a combined ZIP package and README documentation. Creators include researchers from the University of Delaware, IITA, NASRDA, University of Ibadan, University of Maryland and partner institutions.
