Chesapeake Bay Bottom Survey

Polygon dataset characterizing bottom type designations determined by Md DNR's Acoustic Bay Bottom Survey conducted from 1974 to 1983. Bottom type designations include cultch, mud, sand, leased bottom, hard bottom, mud with cultch and sand with cultch. Note: The data in this file is up to 30 years old and areas designated as "cultch bottom" when this survey was conducted have likely degraded. For this reason, it is very likely that many of the areas shown as cultch in the dataset are no longer valiid. The data in this file should only be used as a general guide.

Chesapeake Bay Benthic Habitat

Benthic data were aggregated from multiple sources to create a baywide record of seabed material in the Chesapeake Bay. Habitat polygons are classified with an adaptation of the Coastal and Marine Ecological Classification Standard (CMECS) Substrate Component (SC). Source data were collected during the interval 1842-2014. Because of potential temporal changes in bottom conditions and deficiencies in survey methodology, benthic habitat characterizations may be in error in some areas. These are, however, the best data currently available. This is a subset of an original dataset which may be found here: http://ftp.ncbo.cgclientx.com/ecoscience/Chesapeake_Bay_Coastal_and_Marine_Ecological_Classification_Standard_CMECS/Metadata/MD_Bay_Bottom_Survey/. This dataset contains only acoustic (SONAR) surveyed data for Maryland and Maryland Bay Bottom Survey data.

Charter Wildlife Viewing

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.
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.
Charter Transport

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.

Chesapeake Bay Clayey Silt

This is a data table, in comma-delimited, ASCII format, which contains information about selected physical properties, particularly grain size, of 4,255 surficial sediment samples from the Chesapeake Bay in Maryland. Samples were collected on a 1-km grid by the Maryland Geological Survey (MGS) between June 1976 and August 1984. Consider the age of the data (1976-1984), the sampling density (1-km grid) and the spatial and temporal variability of estuarine sediments in evaluating the fitness for use of this data set. Graphic displays and printed tabular listings derived from this data set may be used in publications and presentations, provided that credit is given to the originators of the data set (see Section 1.1).

Census Tracts 2020

The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of census data and comparison back to previous decennial censuses. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. When first delineated, census tracts were designed to be homogeneous with respect to population characteristics, economic status, and living conditions. Census tract boundaries generally follow visible and identifiable features. State and county boundaries always are census tract boundaries in the standard census geographic hierarchy. In a few rare instances, a census tract may consist of noncontiguous areas.
Census Tracts

The units of geography used for the 2010 Census maps displayed here are the Census tracts. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. When first delineated, census tracts were designed to be homogeneous with respect to population characteristics, economic status, and living conditions. Census tract boundaries generally follow visible and identifiable features. State and county boundaries always are census tract boundaries in the standard census geographic hierarchy. In a few rare instances, a census tract may consist of noncontiguous areas. The data collected on the short form survey are general demographic characteristics such as age, race, ethnicity, household relationship, housing vacancy and tenure (owner/renter).
Census Designated and Incorporated Places 2020

The TIGER/Line Files include both incorporated places (legal entities) and census designated places or CDPs (statistical entities). An incorporated place is established to provide governmental functions for a concentration of people as opposed to a minor civil division (MCD), which generally is created to provide services or administer an area without regard, necessarily, to population. Places always nest within a State, but may extend across county and county subdivision boundaries. An incorporated place usually is a city, town, village, or borough, but can have other legal descriptions. CDPs are delineated for the decennial census as the statistical counterparts of incorporated places. CDPs are delineated to provide data for settled concentrations of population that are identifiable by name, but are not legally incorporated under the laws of the State in which they are located. The boundaries for CDPs often are defined in partnership with State, local, and/or tribal officials and usually coincide with visible features or the boundary of an adjacent incorporated place or another legal entity. CDP boundaries often change from one decennial census to the next with changes in the settlement pattern and development; a CDP with the same name as in an earlier census does not necessarily have the same boundary. The only population/housing size requirement for CDPs for the 2010 Census is that they must contain some housing and population. The boundaries of all 2020 Census incorporated places are as of January 1, 2020 as reported through the Census Bureau's Boundary and Annexation Survey (BAS). The boundaries of all 2020 Census CDPs were delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP).STATEFP 2 String State FIPS codeCONCTYFP 5 String Consolidated city FIPS codeCONCTYNS 8 String Consolidated city GNIS codeGEOID 7 String Consolidated city identifier; a concatenation of current state FIPS code and consolidated city FIPS codeNAME 100 String Consolidated city nameNAMELSAD 100 String Name and the translated legal/statistical area description for consolidated cityLSAD 2 String Legal/statistical area description code for consolidated cityCLASSFP 2 String FIPS class codeMTFCC 5 String MAF/TIGER Feature Class Code (G4120)FUNCSTAT 1 String Functional statusALAND 14 Number Land areaAWATER 14 Number Water areaINTPTLAT 11 String Latitude of the internal pointINTPTLON 12 String Longitude of the internal poinhttps://www2.census.gov/geo/pdfs/maps-data/data/tiger/tgrshp_rd18/TGRSHPRD18_TechDoc.pdf
Census Blocks 2020

Census Blocks are statistical areas bounded on all sides by visible features, such as streets, roads, streams, and railroad tracks, and/or by nonvisible boundaries such as city, town, township, and county limits, and short line-of-sight extensions of streets and roads. Census blocks are relatively small in area; for example, a block in a city bounded by streets. However, census blocks in remote areas are often large and irregular and may even be many square miles in area. A common misunderstanding is that data users think census blocks are used geographically to build all other census geographic areas, rather all other census geographic areas are updated and then used as the primary constraints, along with roads and water features, to delineate the tabulation blocks. As a result, all 2020 Census blocks nest within every other 2020 Census geographic area, so that Census Bureau statistical data can be tabulated at the block level and aggregated up to the appropriate geographic areas. Blocks are the smallest geographic areas for which the Census Bureau publishes data from the decennial census.
Census Block Groups 2020

Block Groups (BGs) are defined before tabulation block delineation and numbering, but are clusters of blocks within the same census tract that have the same first digit of their 4-digit census block number from the same decennial census. Census 2020 BGs generally contained between 600 and 3,000 people, with an optimum size of 1,500 people. Most BGs were delineated by local participants in the Census Bureau's Participant Statistical Areas Program (PSAP).
