This layer is the MGRS 100,000m grid that covers Zone 18S which covers part of Maryland.The U.S. National Grid provides a standardized grid reference system that is seamless across jurisdictional boundaries and allows for pinpointing exact locations. Since USNG is standardized - it can be understood and used as a common geographic framework for response. Zone 18S covers part of Maryland. The vertical UTM boundaries are horizontal latitude band boundaries form (generally) 6 X 8 Grid Zones. Hence - the first three letters of the MGRS value - e.g. '18S' - are referred to as the Grid Zone Designator (GZD). The fourth and fifth characters are a pair of letters identifying one of the 100 - 000-meter grid squares within the grid zone (or UPS area).

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 2010 Census blocks nest within every other 2010 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 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).Feature Service Link:http://geodata.md.gov/imap/rest/services/Demographics/MD_CensusData/FeatureServer/0 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.

In 2000 - the Maryland Geological Survey (MGS) was awarded a Coastal ZoneManagement 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) of Gaithersburg - 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. This data set has been merged into a state wide file for ease of processing and decision making.Feature Service Link:http://geodata.md.gov/imap/rest/services/Boundaries/MD_MarineBoundaries/FeatureServer/0 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.
