mapping access to resources and opportunities for sustainable development

Description

How long does it take to get from A to B and what is the 'cost' of doing so? In a recent paper in the Nature journal Scientific Data, Andy Nelson (Professor of Spatial Agriculture and Food Security at ITC, University of Twente) and colleagues document nine new global and spatially detailed datasets that map travel time to the opportunities, resources and services that are typically concentrated in urban areas. The paper also provides a first spatial validation of the underlying global models and demonstrates that the travel time estimates are plausible and useful in many geographies.
