GRID3 SEN - Settlement Extents v3.0

Center for International Earth Science Information Network

The GRID3 SEN - Settlement Extents v3.0 consists of a geographic representation of settlements in Senegal, in two forms: 1) settlement polygons, and 2) spatial points depicting the centroids of settled grid cells at 3-arc seconds (or ~100 meters) contained within settlement polygons. Both layers include attributes as described in the codebooks. Data inputs and methodology are described in the DataRelease Notes (PDF).

The current version supersedes GRID3 Senegal Settlement Extents, Version 02; the following changes were made:

- Development of a new methodology to derive building counts and settlement polygons with open data.
- Estimation of a probability value for settlement polygons
- Addition of a building-area measure
- Replacement of degree of urbanization with classification based on built-up areas, small settlement areas, and hamlets
- Elimination of building-count ranges
- Elimination of variable comparing to previous versions
