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 potential additional users of the map are other Humanitarian Aid Operators involved in in-field operations. The scope of the map production is to generate a general reference content of the pre-event situation and a damage assessment after the violent conflict between parties in Libya. The conflict started in May-2014 and it is still ongoing. Map products are available in the Copernicus EMS Portal at the following URL: http://emergency.eu/mapping/list-of/components/EMSN033.

Raster layers: Urban sprawl object-based image analysis results for 1988, 2000, 2010 and 2016. Inset maps: Administrative boundaries (GADM 2015). All data sources are complete and with no gaps. The present map shows the results of the urban sprawl analysis. 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. High resolution imagery data (<5m) from Google Earth (2001 and 2010) and Sentinel-2 imagery (10m) for 2017 were used to provide appropriate reference information to validate the built-up classification over the area of interest. For the year 1988 a visual comparison with the available Landsat data has been conducted. All satellite images have been radiometrically enhanced and georeferenced. All satellite images have been atmospherically and geometrically corrected. The estimated thematic accuracy of this product is 80% or better, as it is based on OBIA approach with fuzzy rule sets. Only the area enclosed by the Area of Interest has been analysed.
