GeoAnalytics retained by DuPpage County to develop ArcGIS based floodplain mapping and data management system

SHARE

GeoAnalytics, a U.S. based provider of GIS/LIS technology and management consulting, has been retained by the DuPage County, Illinois Division of Stormwater Management to help migrate its legacy GIS tools and spatial databases into a Floodplain Mapping and Data Management System based on ESRI ArcGIS technology. DuPage County has long embraced the use of GIS to support stormwater management and floodplain mapping. Current goals of the Stormwater Division include migrating its existing technical architecture into ESRI’s ArcGIS 9.x environment. Support services being provided by GeoAnalytics include overall system design covering technology, database, and application components.

GeoAnalytics will also assist with the migration of Stormwater Division legacy ArcInfo coverages into an ArcGIS Geodatabase structure and the development of custom application functionality. The primary focus of data efforts will be on those spatial layers required to support hydrologic and hydraulic modeling, floodplain delineation, and the creation of floodplain maps for regulatory and flood insurance purposes. In addition, the Floodplain Mapping and Data Management System will be designed to meet content and reporting requirements of the U.S. Federal Emergency Management Agency’s (FEMA) map modernization program. Publication of legacy County floodplain GIS data into a format compatible with FEMA’s Mapping Information Platform (MIP) environment has already been accomplished.
