About this dataset

This map illustrates satellite-detected areas potentially damaged and related density and the identified road obstacles in Jérémie city and surrounding areas in Grande Anse department, Haiti. The UNITAR-UNOSAT analysis used a Pleiades satellite image acquired on the 07 October 2016 and Worldview-1 image acquired on 01 May 2015 and 08 December 2014. The UNITAR-UNOSAT analysis in the outskirts of Jeremie combined with Copernicus analysis in Jeremie city, identified 13,013 potentially damaged structures within this map extent. The UNITAR-UNOSAT analysis identified 134 road obstacles and 800 population gathering sites within the map extent.This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR-UNOSAT.

Documentation

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. For damage assessments, refugee or IDP assessments, and similar analyses, these changes are then manually documented in the vector data by the analyst. For flood extractions, landcover mapping and similar analyses, a variety of automated remote sensing techniques are used to extract the relevant information which is then reviewed and revised as necessary by the analyst. In all cases, resulting data is then loaded into a standardized UNOSAT geodatabase and exported asshapefiles for dissemination. This is a preliminary assessment and 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. For damage assessments it should be noted that only significant damage to the structural integrity of the buildings analyzed can be seen in imagery, while minor damage such as cracks or holes may not be visible at all. For flood extractions using radar data it is important to note that urban areas and highly vegetated areas may mask the flood signature and result in underestimation of flood waters. Users with specific questions or concerns should contact unosat@unitar.org to seek clarification.
