Briefings

Researchers at Oak Ridge National Laboratory released LandScan Mosaic, a new dataset estimating global population movement by modeling building occupancy. Built on the existing LandScan Global foundation, this tool aims to enhance disaster response, humanitarian aid, and security planning. The dataset utilizes building usage patterns to infer human presence across the globe.

Key points

• LandScan Mosaic estimates global population distribution by modeling building occupancy patterns throughout the day.
• The dataset is built on the foundation of ORNL's LandScan Global, designed to improve humanitarian and security missions.

Context and limitations

Coverage is limited to regions where building occupancy data is available; specific daily movement patterns are inferred rather than directly measured.
