Global accessibility indicators on the GEMS GridDescription
This API provides access to a suite of global accessibility indicators. The dataset quantifies global accessibility for the year 2015 as an estimate of land-based travel time in minutes to the nearest city and the nearest port, where essential services are likely to be concentrated. The data are suitable for mapping access to cities and ports and for analysis of the inequalities in accessibility by different segments of the population.
