Essential Fish Habitat MapperEntry ID: NOAA_efhmapper
Abstract: The Essential Fish Habitat Mapper is an online tool that displays essential fish habitat, and habitat areas of particular concern, established under the Magnuson-Stevens Fishery Conservation and Management Act. The maps also include areas where steps have been taken to minimize the impact that fisheries have on essential fish habitat, including anchoring restrictions, required fishing gear modifications, and bans on certain types of gear. Users can query information from multiple fishery management plans at once to view habitat maps and lists of species for a specific location.
Quality The following spatial data quality issues should be considered when evaluating how EFH and HAPC data can be effectively used in a geographic information system (GIS). The usage caveats derived from these data issues (included in the data inventory) should be carefully considered when interpreting any analyses based on EFH or HAPC data layers.
Errors in the processing of GIS ... data can sometimes create inaccuracies in the spatial representations of geographic features. While these types of errors can be insignificant when creating large-scale maps, they become more problematic when relying on data to provide accurate information at very specific locations.
All GIS data is created with accuracy and detail appropriate for use at specific spatial scales. When low-resolution data is used in a high-resolution context it may not adequately describe the complexity of the features it is meant to represent.
Geographic and environmental features can change significantly over time, particularly in the marine and coastal environment. As ground conditions change, GIS data representing conditions at a specific point in time will becomes increasingly unreliable.
The metadata describing a GIS dataset is a critical component in evaluating how it can and should be used. If metadata does not exist or if it is incomplete, it can be very difficult to accurately interpret the information that the data provides.
Attempts to refine the spatial extents of EFH using high-resolution habitat or coastline data can result in a data set that has a high probability providing false negative EFH information (i.e. indicates that EFH is not present when it actually might be). In situations where a conservative (or precautionary) analysis is required, highly refined datasets may be too exclusive to appropriately account for the uncertainty involved in spatially defining marine habitat.
