From 2006 to 2007, NOAA's Office for Coastal Management led the effort to process existing digital multispectral imagery (ADS-40) and generate digital benthic habitat data, primarily focusing on Submerged Aquatic Vegetation (SAV) for specific bays along the Texas coastal bend. The resulting data were intended to support the state's Seagrass Monitoring Program, which requires regional SAV mapping for status and trends assessment. The geographic extent of these data include Corpus Christi Bay, Redfish Bay, Aransas Bay, Copano Bay, Lower Laguna Madre, Upper Laguna Madre, and Baffin Bay, covering approximately 2,200 square miles. Benthic habitat data were generated for all estuarine lands below mean high water within the study area. No benthic data were produced for the marine side of the barrier island beaches. The layers available within the data download include area, biotic, geoform, and substrate. Partners: Texas Parks and Wildlife Department, Texas A&M University Center for Coastal Studies

The geographic extent of these data include San Antonio Bay and Espiritu Santo Bay, covering approximately 134 square miles. Benthic habitat data were generated from 2007 orthoimagery for all estuarine lands below mean high water within the study area.

These data provide several geoform data products for the Gulf of Maine derived from NOAA's BlueTopo bathymetric grid products. The spatial domain of these data extends from the landward limit of BlueTopo tiles seaward to the 24-nautical-mile Contiguous Zone boundary. These data support coordinated ocean planning among three state partnership agencies, between state and federal organizations, and for the public at large. The Gulf of Maine is an area rich in history, natural resources, and ocean uses. Effective planning for new infrastructure and changes in ocean use requires accurate data and collaboration among multiple stakeholders and resource management organizations. To address long-expressed regional needs, NOAA's Office for Coastal Management collaborated with the states of Maine, New Hampshire, and Massachusetts to develop a regional geomorphology dataset. This dataset serves as a framework for collaborative planning and assessment. Coastal and Marine Ecological Classification Standard (CMECS) geoforms for the area were generated using NOAA's BlueTopo bathymetric products. Semiautomated methods were employed to ensure consistent mapping of features across the region. Following the semiautomated process, additional interpretation, guided by regional marine geology and mapping experts, was conducted to add and refine features of interest not detected automatically. Efforts to expand and update this product are planned. The layers available within the data download include: confidence_update, geoform, geoform_interpreted, and isobath.

These data were developed to support ecosystem-based management in the Humboldt Bay region. The focus of the mapping effort was on shallow water benthic habitats with particular concern for eelgrass meadows. The study area covers Arcata (North) Bay, Entrance Bay, South Bay, and the Eel River Delta in Humboldt County, California. Humboldt Bay is the largest estuary north of San Francisco Bay and represents a significant resource for the north coast region. Beginning in 2007, NOAA's Office for Coastal Management, in partnership with the California Sea Grant Program and other local organizations, initiated an ecosystem-based management project for the bay. A key component of this project was the establishment of subtidal habitat goals to guide long-term management and provide a framework for conservation efforts across the land-sea interface. The collection of imagery and subsequent delineation of benthic habitat were essential steps for developing and implementing ecosystem-based management in Humboldt Bay's subtidal zone. Collectively, these efforts establish an important and replicable data and information framework crucial for ecosystem-based coastal and marine conservation planning and implementation. The layers available within the data download include biotic, field_point_sample, geoform, and substrate.

These data were collected under a cooperative mapping program between the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration Office for Coastal Management (NOAA\OCM), and the Apalachicola National Estuarine Research Reserve (NERR). The primary objectives of this program were to collect marine geophysical data to develop a suite of seafloor maps to better define the extent of oyster habitats, the overall seafloor geology of the bay and provide updated information for management of this resource. In addition to their value for management of the bay's oyster resources, the maps also provide a geologic framework for scientific research and the public. High-resolution bathymetry, backscatter intensity, and seismic profile data were collected over 230 square kilometers of the floor of the bay. The study focused on the Apalachicola Bay and Western St. George Sound portions of the estuary in mostly in depths > 2.0 meters.

Data produced for the Florida Fish and Wildlife Conservation Commission's Florida Marine Research Institute (FMRI) in partnership with the South Florida Water Management District (SFWMD). This data set consists of digital data describing the seagrass, unvegetated bottom, open water, algal beds, oysters, and apparent shoreline for the Southwest Florida Seagrass project area,which consists of Pine Island Sound, Matlacha Pass, San Carlos Bay, the lower Caloosahatchee River, and Estero Bay, in 1999. The data set includes an ArcInfo coverage that was digitized from 1:24000 scale natural color aerial photographs that were photogrammetrically georeferenced utilizing GPS ground control points. Data was stereoscopically photointerpreted and digitized using a Zeiss P3 analytical stereoplotter. The seagrass beds and additional categories were classified according to the FDOT Florida Land Use, Cover and Forms Classification System (FLUCCS). Minimum mapping unit (mmu) for all classes was 0.25 acres. A Photointerpretation Key was developed to aid in the classification of collected data. Ground truthing was performed during the photointerpretation phase to ensure classification accuracy and consistency of PI. Digital files were created in Microstation design file format (.dgn). 1999 SWIM Seagrass data was translated from ARC/Info to .dgn format and was referenced as collateral tie information during the compilation process.
