Mapping Impervious Surfaces in Support of Stormwater Management Programs (Cobb County, Georgia, USA)

Client: Critigen
Location: Georgia, USA

GISonLine was pleased to provide support through the creation of geospatial feature layers and geodatabases associated with the mapping of impervious surfaces (ex: roofs, driveways, sidewalks, roads, parking lots…etc.) using orthophotos covering an area of ​​over 100 km2 within Cobb County, Georgia, USA.

The Impact

Primary goals of the project were to establish a geodatabase containing the feature layers of impervious surfaces for the purpose of fee collections associated with rainwater run-off and storm water sewer systems.

The Outcome

GISonLine successfully performed digitization and feature layer creation of impervious surfaces using the orthomosaic imagery. In addition, GISonLine provided spatial data quality control and assessment with delivery of a topologically correct vector database to Cobb County, Georgia stakeholders.
