GRID3 NGA - Settlement Extents v4.0
The GRID3 NGA - Settlement Extents v4.0 dataset consists of a geographic representation of settlements in Nigeria. Settlement extents are further delineated into settlement blocks nested within urban and small settlement areas, generated from integrated road, railway, river, settlement extent, building footprint, and remote-sensing inputs. Each block is enriched with morphological, environmental and building metrics.
This version supersedes GRID3 NGA - Settlement Extents v3.1 (https://doi.org/10.7916/x9xg-e262). The following changes were made:
Creation of blocks in urban and semi-urban areas; and
Removal of falsely detected settlements identified during fieldwork
Keywords: Settlements
