We explore some of these applications in this chapter.

Case Study: Disaster Relief

In order to mount effective responses, emergency managers need accurate maps that show the extent of damage, predictions for its potential spread, and detailed data on the movement of people and resources.

Ten years ago, geospatial data wasn’t rich enough to map granular, real-time movements of people and resources even in developed countries. Now that smartphones are ubiquitous around the world, disaster relief agencies are able to use geospatial data that goes down to the level of individuals, as well as maps showing key infrastructure and up-to-date damage assessments created on the fly, in order to manage response efforts.
