City / Hotspot Mapping

Urban and environmental decision makers are confronted with a complex and dynamic environment. For conducting sustainable policies at city level, they require up-to-date information. Our remote sensing team developed efficient data-extraction systems to support these decision making processes.
Land Use / Land Cover Maps provide a quantitative geo-referenced overview of soil occupation. According to the decision makers’ needs, these maps can focus on city areas or natural areas.

A detailed and up-to-date land use map for urban areas is the basic and essential information required by urban planners to plan and manage city development. While focused on natural areas, this land use map is a mandatory tool for environmental planners and agencies. The map can be derived either from digital aerial images or very high resolution imagery (VHR), with a minimum resolution of <1m. The resulting vector dataset is represented at a mapping scale varying from 1:3.000 to 1:10.000.

The Urban Atlas is providing pan-European comparable land use and land cover data for Large Urban Zones (LUZ). An Urban Atlas product can be created for any city or region. Land use information is represented at the level of urban blocks, which identifies all details necessary for urban land use monitoring and planning. The Urban Atlas is derived from satellite imagery with a resolution of 2,5m (results data on a 1:25.000 scale). The legend is derived from the Corine Land Cover nomenclature, improved in precision by adding extra artificial classes.

Change mapping / Historical mapping - As metropolitan areas are growing and changing at unprecedented rates it is important to provide spatio-temporal data which can illustrate where changes have occurred. These data quantify the rate of urban sprawl and the losses in green areas. They are the mandatory reference for understanding urban growth changes with a historical perspective. Historical aerial imagery is available from as early as the late ‘40s; satellite images are available since mid ‘70s. Change maps can be derived from combining recent and historical images.

EUROSENSE also has the capability of creating 3D city maps. More information can be found here.
