At present, accepted methodologies for wind disaster damage assessments rely almost exclusively on responders having ground access to the affected area to document damage to housing structures. This approach can prove both time consuming and inefficient, and does not support the use of drones and satellites.

Geospatially-based damage assessments offer potential improvements to this process in terms of providing responding agencies with previously unavailable information about hard to reach, often non-permissive environments, at a scale and speed not possible through ground-based counts of damaged structures.

This guide provides the first standard method for conducting these types of damage assessments through the analysis of drone and satellite imagery. The “BAR Methodology” has been developed by the Signal Program on Human Security and Technology at HHI to address this critical gap in this evolving area humanitarian practice.
