The Maryland Department of Natural resources began updating the National Wetlands Inventory (NWI) mapping of wetlands in Maryland in the early 1990s. This database lists the 3.75' x 3.75' USGS quadrangles for which 'DNR Wetlands' have been mapped. It identifies the date of source photography used to map wetlands - and the status of mapping effort. This database also gives the five-letter abbreviation used for naming 'DNR_Wetlands' files. In most cases - the first five characters are the first 'five characters' of the 'USGS 7.5' Quad Name.' When completed - the series will provide coverage for the entire State of Maryland.

The Sensitive Shorebird Areas dataset was developed to show all locations in the Maryland Coastal Bays that are sensitive for shorebirds. The dataset is an subset of the National Wetlands Inventory (NWI) dataset. The polygons that were extracted from the NWI dataset were of the NWI_TYPE = E1UB4L and E2FLN. These wetland types represent specific types of subtidal and intertidal mud flats that are desireable to shorebirds. The polygons were further divided into four size classes each containing the same number of polygons. Larger areas were given a higher ranking than smaller areas.Feature Service Link:https://mdgeodata.md.gov/imap/rest/services/Biota/MD_LivingResources/FeatureServer ADDITIONAL LICENSE TERMS: The Spatial Data and the information therein (collectively "the Data") is provided "as is" without warranty of any kind either expressed implied or statutory.

These baseline recreational use data will inform planning efforts being undertaken by the Maryland Department of Natural Resources to help inform public access - land acquisition - future planning and decision-making. Collecting data on the variety of ways the Chesapeake waters and surrounding lands are used will help us plan for reducing use conflicts in our coastal waters - maximizing efficiency - and enhancing environmental and economic productivity. Chesapeake Bay waters are used in many ways: commercial fishing - aquaculture - transport - habitat for wildlife - and recreation - among others. With new and expanding coastal and marine uses - as well as Maryland's growing coastal population - the pressure is mounting to ensure that there is space for both traditional and new uses and that conflicts are minimized. Some mapped human use data exist - but Maryland has limited recreational water use data for the Chesapeake waters.

In 2000 - the Maryland Geological Survey (MGS) was awarded a Coastal Zone Management grant to complete the acquisition of a recent (ca. 1990) digital shoreline for the coastal regions of Maryland -- the Chesapeake Bay - its tributaries - the coastal bays - and the Atlantic coast. MGS contracted the services of EarthData International - Inc. (EDI) - currently of Frederick - Md. - to extract shorelines from an existing wetlands delineation - which was based on photo interpretation of 3.75-minute digital orthophoto quarter quads (DOQQs). In areas where a wetlands coverage was not yet available - EDI interpreted shorelines directly from the orthophotography. DOQQ registration (Maryland State Plane Coordinate System - NAD 83 - meters) was transferred automatically to the shoreline vectors. Following shoreline extraction or interpretation - EDI assigned attributes to the vectors based on shoreline type: beach - vegetated - structure - or water's edge. All four categories are linear features - except 'beach - ' which - if sufficiently wide - can be both linear and polygonal. Shorelines were merged into 7.5-minute quadrangles - provided that the aerial photography on which the DOQQs were based was flown in the same year. MGS used the shorelines to create a series of Shoreline Changes maps. In doing so - MGS erased the landward edge of beach polygons - leaving the seaward edge intact as a linear feature. The Geographic Information Services Division of the Maryland Department of Natural Resources (DNR) merged the shorelines for all of the 7.5-minute quadrangles into a single - statewide coverage. MGS - working collaboratively with Towson University's Center for Geographic Sciences (CGIS) - subsequently used the recent shorelines - along with historical ones - as input into a U.S. Geological Survey (USGS) program - the Digital Shoreline Analysis System (DSAS) (Danforth and Thieler - 1992; Thieler and others - 2001). DSAS determines linear rates of shoreline change (erosion or accretion) along closely spaced - shore-normal transects. Based on DSAS output - the collaborators assigned the following erosion rate categories as attributes to the recent shoreline - clipped by county from the statewide coverage: a) High erosion rate (more than 8 ft/yr) - b) Moderate erosion rate (4-8 ft/yr) - c) Low erosion rate (2-4 ft/yr) - d) Slight erosion rate (0-2 ft/yr) - e) No change - f) Accretion - g) Protected - h) Unknown and i) No Data The DOQQs from which the shorelines were interpreted meet National Map Accuracy Standards at the production scale of 1:12 - 000 using the American Society for Photogrammetry and Remote Sensing(ASPRS) method. Consider the scale in displaying and using the vectors. Displaying the vectors at scales larger than those of the source documents is considered bad practice. See Horizontal Positional Accuracy Report for positional inaccuracies in the data set. The aerial photography from which the DOQQs were developed was not tide-coordinated. Therefore - shoreline in this data set do not reprsent a consistent vertical datum.
