Tanzania travel time to nearest health centre

Travel time surface was estimated using the cost allocation (friction surfaces) which used three primary input datasets on land surface characteristics that help or hinder travel speeds: land cover, roads and topography. This Geotiff is a 20-m spatial resolution surface where each pixel has a value which is the time in seconds to travel to the nearest health centre documented in the paper by Maina et al. (2020) doi: 10.1038/s41597-019-0142.
