Aerial photographs taken by NOAA's National Geodetic Survey during 1992 were mosaicked and orthorectified by the Biogeography Branch. The resulting image was used to digitize benthic, land cover and mangrove habitat maps of the Salt River Bay National Historic Park and Ecological Preserve (National Park Service), on St. Croix, in the U.S. Virgin Islands.The mosaic is centered on the National Park Service Site, located on the north central coast of St. Croix, and in some areas extends beyond the park boundaries up to 2 km.

This data set contains sensitive biological resource data for rare plant species and vernal pools in Massachusetts and Rhode Island. Vector polygons in this data set were primarily derived from 2016 RI DEM Natural Heritage Areas and 2016 MADFW NHESP data. Species-specific abundance, seasonality, status, life history, and source information are stored in associated data tables (described below) designed to be used in conjunction with this spatial data layer. This data set is a portion of the ESI data for Massachusetts, Rhode Island. As a whole, the ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil, and include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.

This data set contains sensitive biological resource data for marine mammals in Massachusetts and Rhode Island. Vector polygons in this data set represent known dolphin, whale, and pineped concentration areas and haul-out sites.

See also the M_MAMPT (Marine Mammal Point) data layer for additional seal information.

The probability rating which covers landcover mapping provides a continuum of wetness from dry to water. The layer is not a wetland classification but provides the wetland likelihood at a specific location. The rating was developed through a modelling process combining multiple GIS and remote sensing data sets including soil characteristics, elevation, existing wetland inventories, hydrographical extents and satellite imagery . Data available via download from the Digital Coast, either from customizable download in NOAA's Digital Access Viewer or FTP download by regions.

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set includes mosaicked aerial photographs for the Sabine Refuge Marsh Creation (CS-28) project for 2021. This data is used as a basemap land-water classification. It also serves as a visual tool for project managers to help them identify any obvious problems or land loss within their project boundary. To better evaluate the effectiveness of restoration efforts, a land-water classification is performed on specific CWPPRA sites to help assess landscape changes.

This dataset was collected by staff of the Environmental Data Center (EDC) at The University of Rhode Island in cooperation with the Northeast Coastal and Barrier Network (NCBN) of the National Park Service (NPS) under the project: Field Technician Support for Elevation Mapping of NPS Salt Marshes and other sites for Sea Level RIse Planning and Post- and Future Storm Evaluation which is a modification to Task Agreement P13ACAC00891 of Cooperative Agreement P09AC00212 Elevation Mapping of Critical Park Areas for Planning and Post- and Future Storm Evaluation and Modeling. The data was collected from Summer 2014 to Fall 2016 at Assateague Island National Seashore (ASIS), Fire Island National Seashore (FIIS), and Gateway National Recreation Area-Sandy Hook Unit. These datasets consist of point locations where vegetation surveys were conducted in salt marshes. Sample locations were determined by overlaying a 20 meter grid of points on salt marsh sites determined by the NCBN. Field crews navigated to every grid point, placed a meter square plot on the ground and sampled vegetation, identifying species type and percent cover (using the Braun-Blaunquet cover-abundance scale). At any given point/plot there may be multiple points with the same coordinates representing the different species present at that location. High accuracy elevation data was also collected at the same locations using RTK-GPS equipment. This data can be found in the same project folder on the NPS Integrated Resource Management Applications (IRMA) website.

These data were collected by the National Oceanic Atmospheric Administration National Geodetic Survey Remote Sensing Division using a Riegl VQ880G system. The data were acquired from 20140829 - 20140919. The data includes topobathy data in an LAS 1.2 format file classified as unclassified (1), ground (2), noise (7), water column (25), bathymetric point (26), topobathy water surface (27), submerged object (29), and International Hydrographic Organization (IHO) S-57 object (30) in accordance with the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards. This data set may also include lidar intensity values and encoded RGB image values.

The National Oceanic and Atmospheric Administration (NOAA) has the statutory mandate to collect hydrographic data in support of nautical chart compilation for safe navigation and to provide background data for engineers, scientific, and other commercial and industrial activities. Hydrographic survey data primarily consist of water depths, but may also include features (e.g. rocks, wrecks), navigation aids, shoreline identification, and bottom type information. NOAA is responsible for archiving and distributing the source data as described in this metadata record.
