Cox's Bazar Refugee Settlement Roads and Footpaths

REACH / UNOSAT datasets and maps are produced using a variety of methods. In general, analysts closely review satellite imagery, often comparing two or more images together, and determine notable changes between the images. In this instance, analysts review best available imagery and manually digitize the centerlines of roads and footpaths in refugee settlements.

This is a rapid analysis which has not yet been validated in the field. It is important to consider the characteristics of the source imagery used in the analyses when interpreting results. Users with specific questions or concerns should contact reach.mapping@impact-initiatives.org to seek clarification.
