Locating impervious surfaces for better management of water runoff to prevent flooding, erosion . . . . . .
Updated and detailed maps of impervious surface areas in several thematic classes
Consistent and objective mapping, easily facilitating future updated maps
Delivery of the input satellite image in GIS format
Urban planners use the maps to locate areas that may benefit from urban green planning or water infrastructure investments
Hydrological modelers use maps of impervious surface areas as key input for modelling of urban storm water runoff
Public decisionmakers use the maps to monitor the overall green status of the urban areas
The thematic maps cover classes such as impervious areas, roads, buildings, vegetation and water
Data is ready for use in hydrological modelling software or Geographic Information Systems (GIS)
Mapping can be done based on existing aerial photos or on satellite imagery down to 30 cm spatial resolution
For river basin mapping, it is possible to perform the mapping at smaller map scales, using medium resolution satellite images
Prices starting at 75 EUR/sqkm
The price of Impervious Surface Mapping varies and relates to factors such as size of the area, input data types and availability of ancillary data
