Title
GRID3 COD - Travel Time Friction Surface v1.0
Description
The aim of this work is to generate two friction surfaces for modeling physical accessibility in the Democratic Republic of the Congo: one incorporating walking speed only, and another combining walking and motorized travel speeds. Motorized speeds are applied exclusively on roads that are present and passable by vehicles; in all other areas, walking speeds are used. The GRID3 COD - Travel Time Friction Surface v1.0 dataset is a spatial data layer in tiff format. The datasets contain 2 layers: (1) GRID3_COD_walk_travel_time_friction_surface_v1_0.tif - Applies walking speeds across the entire surface, adjusted for slope and elevation. (2) GRID3_COD_mix_travel_time_friction_surface_v1_0.tif - Applies motorized speeds on roads and walking speeds in all other areas. The resolution is 30 m. The unit of measurement in both surfaces is minutes per meter. Suggested Dataset Citation Center for Integrated Earth System Information (CIESIN), Columbia University. 2026.
