Network analysis DEMs
network analysis We assisted the Department of Basic Education to identify remote rural schools for a teacher incentive scheme. There were two components to this: categorising towns by size, and calculating the distance by road of schools from each category of town. dem A Digital Elevation Model (DEM) can be used for visualising terrain, conducting visibility analysis and for generating river catchments and stream networks. We have used DEMs for numerous projects including calculating river profiles, analysing road steepness and mapping the visual impact of powerline pylons.
