Title
GRID3 TZA - Settlement Extents v3.0
Description
The GRID3 TZA - Settlement Extents v3.0 consists of a geographic representation of settlements in Tanzania, 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. The current version supersedes GRID3 Tanzania Settlement Extents, Version 02; the following changes were made: (1) Development of a new methodology to derive building counts and settlement polygons with open data. (2) Estimation of a probability value for settlement polygons (3) Addition of a building-area measure (4) Replacement of degree of urbanization with classification based on built-up areas, small settlement areas, and hamlets (5) Elimination of building-count ranges (6) Elimination of variable comparing to previous versions Recommended Citation: Center for International Earth Science Information Network (CIESIN), Columbia University. 2024.
