Limited Area Shorelines by Decade

The Maryland Geological Survey (MGS) developed this shoreline feature class as part of a project to calculate updated rate of change information for Anne Arundel, Baltimore, Harford and Prince George's Counties. These 5 counties have specifics related to each for the shoreline erosion anaylsis and the details are designated within the metadata. This shoreline data set spans the time period 1932-2010, and was used as input to the U.S. Geological Survey (USGS) Digital Shoreline Analysis System (DSAS) v4.3 program to calculate long-term and short-term rates of change (erosion and accretion).
Legacy Historical Shorelines by Years

This Legacy Historical Shorelines is a subset of the Maryland Historical Shorelines data set with 5 counties being excluded from the shorelines which are Anne Arundel, Balimore, Calvert, Harford and Prince George's County. The remaining counties have these digital shoreline vectors which are used to overlay orthophoto base map rasters of the Maryland shoreline and show historical shoreline locations in relation to the Rates of Change (ROC) erosion level transects data. Acquired as part of multi-year Shoreline Changes mapping project to show erosion and other shoreline shifts along Maryland's Chesapeake Bay and tidal tributaries. The newer county shoreline data can be viewed using the "Limited ROC Shorelines by Decade" map layer and this Legacy Shoreline layer will be replaced by the Limited ROC Shorelines by Decade as counties are updated over time.
Large Rivers Lakes and Ponds

This layer is extracted from The High Resolution National Hydrography Dataset Plus (NHDPlus HR). This is an integrated set of geospatial data layers, including the best available National Hydrography Dataset (NHD), the 10-meter 3D Elevation Program Digital Elevation Model (3DEP DEM), and the National Watershed Boundary Dataset (WBD). The NHDPlus HR combines the NHD, 3DEP DEMs, and WBD to create a stream network with linear referencing, feature naming, "value added attributes" (VAAs), elevation-derived catchments, and other features for hydrologic data analysis.
Land Trails

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.

ICC Vehicle Volume Data

This dataset shows the number of vehicles that have passed under a gantry on that particular day. This dataset does not show trips, it only shows segments. Segments are compiled to make trips. There are 10 gantries on the InterCounty Connector (ICC) and 5 interchanges. The eastbound gantries are 101, 105, 107, 109, 113, and the westbound gantries are 102, 106, 108, 110, 114. The dataset has a column for each gantry going east and west, then a total for each gantry. The ICC is an all electronic tolling road which opened February 2011. The first opening was a partial opening, with only the first interchange being available for use.There was a free period from February 23, 2011 through March 6, 2011. The rest of the ICC opened in November 2011, and there was another free period from November 22, 2011 through December 4, 2011. There are a few days where a low number of traffic passed under gantries (rows 196,198, 269,271...), these were either testing periods or construction vehicles.
Hydric Soils

This data layer is a compilation of the MUPOLYGON feature class, muaggatt table and component table of the Gridded Soil Survey Geographic (gSSURGO) Database for Maryland. United States Department of Agriculture, Natural Resources Conservation Service. Under the direction of the Watershed Resources Registry (WRR) Technical Advisory Committee (TAC) this data has been altered from its original state. A reclassification of the hydric classification field was performed which classifies all soil map units consisting of less that 40% total hydric soils as not hydric, all soil map units from 41% - 79% as partially hydric and all soil map units 80% and greater as hydric. This reclassification was performed to provide a more refined input for modeling purposes. A full version of this database is available at: http://datagateway.nrcs.usda.gov/. (FY2014 official release).

Preservation Easements

A historic preservation easement is a type of conservation easement designed to protect a significant historic, archaeological, or cultural resource. Easements are contractual agreements between a property owner and a holding organization. Those preservation easements with the State of Maryland are managed by the State Historic Preservation Office (The Maryland Historical Trust). Generally, the owners of the easement property agree to relinquish partial development rights, to maintain the property, to provide limited public access, and to obtain prior approval for any changes or alterations. In exchange, The Maryland Historical Trust promises to protect the property by ensuring continuous compliance with the terms of the Easement. The Trust is also available to advise owners on the correct and best methods of preserving and using their properties. For more information see: https://mht.maryland.gov/Pages/easement/easement.aspx.

Preliminary FEMA Floodplain

This layer offers the anticipated floodplain boundaries however, the data shown are in the process of being reviewed and adopted by FEMA and a given community. Changes to the Preliminary boundaries may occur before official map adoption. Use this layer with caution. The effective regulatory floodplain should be used for conducting all official floodplain determinations until such time the preliminary floodplain is reviewed and adopted by FEMA and a given community. It is reasonable to assume that preliminary floodplain boundaries are more accurate than the Q3, but the Q3 may better represent the current regulatory Flood Insurance Rate Map (FIRM) when verified by using the paper FIRM.

NAIP Seamlines

This data set contains polygons delineating the seamline boundaries of imagery acquired as part of the National Agriculture Imagery Program (NAIP), and used in the creation of DOQQs and compressed county mosaics (CCM). These seam polygons can be used as a tool in determining the image source and date of each portion of the DOQQ or the CCM. The NAIP acquires 4 band digital ortho imagery from airborne and/or space based platforms during the agricultural growing seasons in the U.S.. A primary goal of the NAIP program is to enable availability of ortho imagery within sixty days of acquisition. The NAIP provides 1 meter or 60cm GSD ortho imagery rectified within +/- 6 meters to true ground at a 95% confidence level. The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 (plus or minus 30) pixel buffer on all four sides. The NAIP quarter quads are formatted to the UTM coordinate system using the North American Datum of 1983 (NAD83).
