Title: Damage Assessment in the towns of Ayutla and San Nicolas Tolentino, Municipality of Izúcar de Matamoros, State of Puebla, Mexico
Contributors:- Point data
- 2017
Summary: This map illustrates satellite-detected, potentially damaged structures in the towns of Ayutla and San Nicolas Tolentino, Izucar de Matamoros Municipality, Puebla State, Mexico. The analyzed area is located approximately 1.5 km West from the epicenter of the 7.1M earthquake that struck the central eastern part of Mexico on 19 September 2017. UNITAR-UNOSAT identified 423 potentially damaged structures, from which 240 are within San Nicolas Tolentino, 172 in Ayutla and 11 in Dulces Nombres. The analysis was performed using a post-event Pleiades satellite image acquired on 22 September 2017 and a pre-event WorldView-2 satellite image acquired on 11 April 2017. This is a preliminary analysis 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.

Title: United Nations Operational Satellite Applications Programme - GIS Maps and Data
Contributors:- Not specified
Summary: 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.
