GRID3 SLE - Settlement Extents v3.0

The two layers contained within the GRID3 SLE - Settlement Extents v3.0 include: GRID3_SLE_settlement_extents_v3.gpkg: a spatial layer representing settlement polygons. GRID3_SLE_settlement_grid_v3.gpkg: a spatial layer representing the centroids of settled grid cells. The current version supersedes GRID3 SLE - Settlement Extents v2.0; 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 For more information on data inputs, methodology, and codebooks please see the Data Release Notes.
