Chesapeake Bay Contours

Bathymetry for Chesapeake Bay was derived from two hundred ninety-seven surveys containing 3,178,509 soundings. Thirty-five older, less accurate, overlapping surveys were entirely omitted before tinning. Partial overlap from other older, less accurate surveys was also omitted prior to tinning. The surveys used dated from 1859 to 1993. Thirty-six surveys dated from 1859 to 1918, thirty-seven from the 1930s, ninety-one from the 1940s, sixty- six from the 1950s, twenty-five from the 1960s, twenty-four from the 1970s, fourteen from the 1980s, and four from the 1990s. The total range of sounding data was 3.7 meters to -50.4 meters at mean low water. Mean high water values between 0.2 and 1.2 meters were assigned to the shoreline. Fifteen points were found that were not consistent with the surrounding data and were removed prior to tinning. DEM grid values outside the shoreline (on land) were assigned null values (-32676). Chesapeake Bay has two hundred eighteen 7.5 minute DEMs and ten one degree DEMs. The 1 degree DEMs were generated from the higher resolution 7.5 minute DEMs which covered the estuary. A Digital Elevation Model (DEM) contains a series of elevations ordered from south to north with the order of the columns from west to east. The DEM is formatted as one ASCII header record (A- record), followed by a series of profile records (B- records) each of which include a short B-record header followed by a series of ASCII integer elevations (typically in units of 1 centimeter) per each profile. The last physical record of the DEM is an accuracy record (C- record). The 7.5-minute DEM (30- by 30-m data spacing) is cast on the Universal Transverse Mercator (UTM) projection. It provides coverage in 7.5- by 7.5-minute blocks. Each product provides the same coverage as a standard USGS 7.5-minute quadrangle but the DEM contains over edge data. Coverage is available for many estuaries of the contiguous United States but is not complete.This layer was modified from its original form. Please see lineage section for details.Not to be used for Navigation. Acknowledgment of the National Oceanic and Atmospheric Administration- Nation Ocean Service would be appreciated in products derived from these data. The datum for these bathymetric DEMs is not the same as that used by the US Geological survey (USGS) for land based DEMs which results in a discontinuity if the two datasets are merged together. Moreover, the shoreline for the USGS DEMs is indeterminate and not the same as that used for the Bathymetric DEMs. The data within the bathymetry file is floating point. When using the data within a GIS care must be taken to ensure that the data are being read as floating point and not integer data.

Maryland, through its Coastal Zone Management (CZM) Program, is collecting information on how the public uses the Chesapeake Bay waters and adjacent lands. These baseline data will inform planning efforts being undertaken by the Maryland Department of Natural Resources to help inform public access, land acquisition, and future oyster aquaculture planning and decision-making. Collecting data on the variety of ways our Chesapeake waters 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. Basic data on how we use our coastal waters was collected by inviting residents and experts to share their knowledge about recreational uses at workshops using geographical information systems technology.

As a member of the Mid-Atlantic Regional Council on the Ocean (MARCO), Maryland, through its Coastal Zone Management (CZM) Program is collecting information on how the public uses the Atlantic coast of Maryland. These baseline data will inform planning efforts being undertaken by the Maryland Department of Natural Recources to help develop a Maryland Ocean Plan. Collecting data on the variety of ways you use the Seaside Bays and Atlantic Ocean will help us plan for reducing use conflicts in our coastal waters, maximizing efficiency, and enhancing environmental and economic productivity. State and federally managed waters of Maryland and the U.S. are used in many ways: commercial fishing, aquaculture, shipping, military exercises, sand mining, habitat for wildlife, and recreation. With new and expanding coastal and ocean uses emerging such as energy production and increased shipping and considering Maryland coastal population is increasing, 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 its Atlantic Coast and Coastal Bays. So basic data on how we use our coastal waters will be collected by inviting residents and experts to share their knowledge about recreational uses at workshops using geographical information systems technology.

Physiographic Provinces

This data layer contains the Province-level physiographic subdivisions of Maryland in ArcGIS format. The file was developed from components of a detailed digital physiographic map of Maryland by James P. Reger and Emery T. Cleaves, currently in progress. 

Physiography is the study and classification of the natural landscape of the earth and the landforms that comprise it.  The approach for the detailed physiographic map of Maryland is hierarchical and descriptive.  Subdivisions are based on similarities (within) and differences (among) geologic structure, rock type, geomorphic history, and topographic characteristics.  Data and subdivisions were compiled at a 1:100,000 scale for the detailed state-wide map. The hierarchical classification of the detailed physiographic map (in progress) includes subdivisions as follows, in descending order (and generally decreasing size): Province, Section, Region, District, Area.  In Maryland there are portions of five physiographic Provinces. 

In this file, the polygons reflect Province level subdivision. The polygon feature attribute table has been developed to pertain only to the Provinces level.  The table includes information on dominant rock types, geologic structure, topographic relief, and drainage pattern.

Prince Georges 10 years Shoreline Erosion Level

To quantify shoreline rates of change (erosion or accretion), Maryland Geological Survey (MGS) used historical and recent shorelines spanning 1993-2010 as input into the Digital Shoreline Analysis System (DSAS) Version 4.3. DSAS, a computer program developed by the U.S. Geological Survey (USGS), determines linear rates of shoreline change along closely spaced, shore-normal transects. Based on DSAS output, MGS assigned generalized rate of change categories as attributes to a recent shoreline for Prince George's County. This recent shoreline consisted of the National Oceanic and Atmospheric Administration (NOAA) Continually Updated Shoreline Product (CUSP) digital shoreline currently available for Prince George's County; and 2) portions of the Maryland Department of Natural Resources (MD DNR) Critical Area Commission (CAC) digital shoreline for Prince George's County. Based on the results of an End Point Rate (EPR) analysis on the ca. 1990s shoreline and the ca. 2000/2010 shoreline (recent shoreline), MGS grouped the rate results into the following general categories: (a) No change (-0.01 to 0.01 feet/year), (b) Accretion (greater than 0.01 feet/year), (c) Slight erosion rate (0 to -2 feet/year), (d) Low erosion rate (-2 to -4 feet/year), (e) Moderate erosion rate (-4 to -8 ft/yr), (f) High erosion rate (greater than -8 feet/year), (g) Protected, (h) No data (insufficient shorelines to calculate 10-year EPR rate), (i) No data (no transects cast; unprotected or unknown shoreline condition), and (j) Rates not delivered (calculated rates suspect). The NOAA CUSP shoreline represents the shoreline position in Prince George's County between the years 2005-2010. The CAC shoreline represents the shoreline position in Prince George's County in 2007. In Prince George’s County, the NOAA CUSP data set covered approximately 60% of the shoreline in the county. MGS decided to supplement the NOAA CUSP data with CAC data in the following areas where NOAA CUSP data was missing: Anacostia River, from approximately the Bladensburg Road bridge, north to the Decatur Street bridge; Northwest Branch Anacostia River, from approximately the 38th Street bridge, south to its confluence with the Anacostia River; the lower reaches of Swanson Creek, west of Chalk Point; Spice Creek and an unnamed creek north of Spice Creek; and Patuxent River and its major tributaries, from approximately the Merkle Wildlife Sanctuary, north to the upper reaches of the Patuxent River. To identify which shoreline source is responsible for a shoreline segment, view the "DSAS_SRC" attribute table field -- "CAC" indicates a shoreline sourced from MD DNR CAC data set; "NOAA CUSP" indicates a shoreline sourced from the NOAA CUSP data set. Negative rate of change values indicate erosion, and positive values indicate accretion. In general, MGS tried to attribute lengths of shoreline of at least 80 meters in length sharing similar rates of change.
