Assessment of Households' Spatial Access to Water Points in Dodoma Rural Wards
Description
Rural Wards of Dodoma Urban District shapefile was extracted from the 2012 Wards shapefile obtained from the National Bureau of Statistics (NBS) of Tanzania downloaded at https://www.nbs.go.tz/index.php/en/census-surveys/gis/386-2012-phc-shapefiles-level-three. The shapefile of the randomly sampled nine Rural Wards studied in this study was extracted from the Rural Wards of Dodoma Urban District shapefile. The household size of each of the nine Rural Wards was extracted from the 2012 Population and Housing Census report of the NBS [24]. Waterpoint data were derived from the Directorate of Rural Water Supply (DRWS) of Tanzania through the Government Basic Statistics Portal. The catchment areas were generated in this study using water point data as input and buffer tool in QGIS 3.10.5 software. Households shapefile was generated by extracting households within catchment areas from Google Earth through digitization. Households folder contain household shapefile containing calculated spatial accessibility indices (Ai). Water point folder contain water point shapefile with fields containing water points capacity (Sj), water demand (Dj) and service (Rj).
