Description
Activation date: 2017-03-08
Event type: Humanitarian
Activation reason:
EMSN033 is a satellite based conflict damage assessment of three selected areas of interest (AOIs) in Libya: Benghazi city, Benghazi´s Aerodrome (El Benina) and Al-Jawf.The scope of the map production was to generate general reference content of the pre-event situation, including administrative boundaries, road network, urban land use classification, urban sprawl and urban expansion velocity analysis.The core users of the map are the Foreign Policy Instruments (FPI) of the European Commission and United Nations Human Settlements Programme (UN-Habitat).The risk and recovery product is a damage assessment point layer representing all affected assets. Damages were detected by visual comparison of pre-event WorldView-2 images from 2012-2013 to the most up-to-date imagery WorldView-3 from 2017. Observations are classified into 4 categories: destroyed asset, severe, moderate or possible damage.Object-based image analysis (OBIA) was used to identify the built-up area based on Landsat 4-5 TM, Landsat 7 ETM+, Landsat 8 OLI/TIRS and Global Land Survey data with a spatial resolution of 30m.To compute urban sprawl, satellite images were classified as built-up and not built-up for reference years of 1988, 2000, 2010 and 2016.
