General Technical Documents Beyond Borders: Satellite Applications for Humanitarian Emergencies

Humanitarian actors continually make complex decisions in the preparation for, and response to, humanitarian emergencies. Digital technologies support these decisionmaking processes by providing large volumes of high-quality data that enables insight. The term “digital data for development (D4D)” refers to the use of data generated by mobile, satellite, and digital devices to inform and strengthen nonprofit, humanitarian, and public-sector decision-making.

Satellite applications, as digital technology, provide a unique source of data about people and their surrounding environment and can fill significant data and information gaps in management and decision-making processes. Often this data may not exist in any other form (e.g., in remote or conflict areas). In other cases, satellite applications may offer data that is more frequent, more detailed, and more affordable than groundbased data sources, such as traditional maps, census data, bespoke surveys, ground teams, or even innovative methods like the use of drones.
