NOAA Site Case Data Management Support

National oceanic and atmospheric administration (NOAA)

The Assessment and Restoration Division (ARD) of NOAA is responsible for evaluating and restoring coastal and estuarine habitats damaged by hazardous waste releases, oil spills, and vessel groundings. Exa Data & Mapping Services has a long-term relationship with NOAA ARD integrating contaminant chemistry and bioassay data into analysis applications such as Query Manager and DIVER in support of the Great Lakes Restoration Initiative (GLRI) and CERCLA site cases. As part of the processing of datasets, Exa maps and converts spatial coordinates from state-based coordinate systems into the North American datum coordinate system using ArcGIS and QGIS platforms. Exa also provides spatial analysis and spatial model development within ArcGIS and QGIS to create river mile grids and automate the assignment of database identifiers using geographic criteria.
