Stormwater Mapping Program, Covington, Georgia/USA

The City of Covington is located 35 miles east of Atlanta, Georgia. It is a “full service city” that hasbeenmaintaining an enterprise GIS since 1999. Currently, all updates to the GIS that require field surveying are conducted.

internally by the GIS Department. Project Description The task was to identify individual drainage networks and sub-basins from beginning to outfall, to survey all structures and determine network connectivity and to populate attributes for all accessible structures.x All of the project data was to bex cataloged in ESRI's geodatabase format for subsequent engineering analyses of the city's stormwater infrastructure. “The Leica MobileMatriX interface is very intuitive and very easy because it is built on ESRI's ArcMap - a software we were already accustomed to using”, said Isaac Standard, City of Covington GIS Project Leader.

Benefits
“Leica MobileMatriX enabled the reduction of a dependency on consultants for survey data collection,” said Standard.
