Cox's Bazar District - Refugee Camp Structure/Shelter/Infrastructure Footprints March 2020

Summary: This is a DRAFT version of the March 2020 structure footprint.

This footprint does not include structures for camps 14, 15, 16 or 27. These will be added as soon as they become available (approx. August 2021). If you wish to recieve a notification of this upload, please contact REACH - Ben.Smith@reach-initiative.org. These structures can be found in the 2019 footprint.

This file represents digitization work carried out by UNOSAT and REACH (March-April 2021) using IOM-NPM drone imagery from March 2020. Work is currently ongoing and the file is reflective of efforts up to 28 April 2021. As future iterations and improvements to the footprints are made, additional versions will be released.

Limitations: Digitised areas show covered spaces within the camps. These may be latrines, tubewells, bathing stations, shelters or larger structures (many of which are multiple shelter joined under one continuous roof). This is also the case in previous 'shelter' footprints. Bridges are not included in this dataset, but many can be found in the previous 2019 footprint.

The work has not been ground truthed and is based on expert interpretation of UAV imagery. In addition to relying on imagery interpretation, the footprints are bound by the limitations present in the UAV images that were utilized.

Summary: This is the most up-to-date shelter footprint for the Rohingya camps. This file represents digitization work carried out by UNOSAT and REACH (March-May 2019) using IOM-NPM drone imagery from January 2019. Work is currently ongoing and the file is reflective of efforts up to 07 May 2019. As future iterations and improvements to the footprints are made, additional versions will be released.

The original classification scheme developed by UNOSAT was comprised of two structure classes: "Structure" and "Bridge." An area based classification was then performed in which all polygons < 5 m2 were reclassified as " 5 m2 also retained the UNOSATs original classification. Additionally, attribute fields containing camp name information, and the image source information were added.

Limitations: The work has not been ground truthed and is based on expert interpretation of UAV imagery. In addition to relying on imagery interpretation, the footprints are bound by the limitations present in the UAV images that were utilized.
