Esri ArcGIS Online (AGOL) Map Image Layer which provides access to the MDOT SHA Recorded Plats data product.MDOT SHA Recorded Plats consists of polygon geometric features which represent the boundary of georeferenced MDOT SHA right of way plats throughout the State of Maryland. All plats included are recorded, that is to say they are recorded in land records as legal instruments. Each plat has a link to a scanned image on the Maryland State Archives (MSA) website (https://plats.net). This boundary data is owned by the MDOT SHA OHD Plats & Surveys Division (PSD). This information is for general informational purposes only and should be confirmed by MDOT SHA PSD to be deemed official.This data is updated nightly through an automated process which pulls data from several sources to create the plat bounding boxes. The process of georeferencing MDOT SHA right of way plats is ongoing. The plats in this data only represent plats that have been georeferenced. The sources include:PSD data for the location (corners) of platsORE data for information about platsThere are three criteria for a plat to be included in this data:The recorded date must be populatedThe plat corner coordinates must be entered by PSDThe plat URL must be populated by PSDFor more information, contact MDOT SHA OIT Enterprise Information Services:Email: GIS@mdot.maryland.gov

This is a MD iMAP hosted service layer. Find more information at http://imap.maryland.gov. These data map hub and corridor elements within the green infrastructure. The Green Infrastructure Assessment was developed to provide decision support for Maryland's Department of Natural Resources land conservation programs. Methods used to identify and rank green infrastructure lands are intended soley for this use. Other applications are at the discretion of the user. The Maryland Department of Natural Resources is not responsible for any inaccuracies in the data and does not necessarily endorse any uses or products derived from the data other than those for which the data were originally intended. Maryland's green infrastructure is a network of undeveloped lands that provide the bulk of the state's natural support system. Ecosystem services - such as cleaning the air - filtering water - storing and cycling nutrients - conserving soils - regulating climate - and maintaining hydrologic function - are all provided by the existing expanses of forests - wetlands - and other natural lands. These ecologically valuable lands also provide marketable goods and services - like forest products - fish and wildlife - and recreation. The Green Infrastructure serves as vital habitat for wild species and contributes in many ways to the health and quality of life for Maryland residents. To identify and prioritize Maryland's green infrastructure - we developed a tool called the Green Infrastructure Assessment (GIA). The GIA was based on principles of landscape ecology and conservation biology - and provides a consistent approach to evaluating land conservation and restoration efforts in Maryland. It specifically attempts to recognize: a variety of natural resource values (as opposed to a single species of wildlife - for example) - how a given place fits into a larger system - the ecological importance of natural open space in rural and developed areas - the importance of coordinating local - state and even interstate planning - and the need for a regional or landscape-level view for wildlife conservation. The GIA identified two types of important resource lands - hubs"" and ""corridors."" Hubs typically large contiguous areas - separated by major roads and/or human land uses - that contain one or more of the following: Large blocks of contiguous interior forest (containing at least 250 acres - plus a transition zone of 300 feet) Large wetland complexes - with at least 250 acres of unmodified wetlands; Important animal and plant habitats of at least 100 acres - including rare - threatened - and endangered species locations - unique ecological communities - and migratory bird habitats; relatively pristine stream and river segments (which - when considered with adjacent forests and wetlands - are at least 100 acres) that support trout - mussels - and other sensitive aquatic organisms; and existing protected natural resource lands which contain one or more of the above (for example - state parks and forests - National Wildlife Refuges - locally owned reservoir properties - major stream valley parks - and Nature Conservancy preserves). In the GIA model - the above features were identified from Geographic Information Systems (GIS) spatial data that covered the entire state. Developed areas and major roads were excluded - areas less than 100 contiguous acres were dropped - adjacent forest and wetland were added to the remaining hubs - and the edges were smoothed. The average size of all hubs in the state is approximately 2200 acres. Corridors are linear features connecting hubs together to help animals and plant propagules to move between hubs. Corridors were identified using many sets of data - including land cover - roads - streams - slope - flood plains - aquatic resource data - and fish blockages. Generally speaking - corridors connect hubs of similar type (hubs containing forests are connected to one ano

This is a MD iMAP hosted service. Find more information at http://imap.maryland.gov. In 1993 - the Maryland Department of Planning and the Maryland State Highway Administration entered into a Data Base Usage Agreement with Bell Atlantic and Data Chromatics - Inc. to develop an enhanced street address map for Maryland. ZIP Code boundary area files were one of the products derived from this partnership. The resulting boundary area files were intended to improve the cartographic quality and accuracy of the ZIP code boundary area files derived from the U.S. Census Bureau's post 1990 Census TIGER\Line Files (based on the Census Bureau's ZIP code tabulation areas - ZCTAs). Subsequent iterative improvements to the ZIP Code boundary area files have been made using premise address information associated with mapped parcel records as provided in the Maryland Department of Planning's MdProperty View GIS tax map and parcel record DVD product. The resulting files are meant to serve as a good approximation"" of ZIP codes as polygons (which in reality they are not) but are not official ZIP Code maps and are not meant to be a substitute for any products offered by the U.S. Postal Service - the official source for ZIP code information. While there are no restrictions on their use we do recommend that they are best used with MdProperty View and that MDP makes no guarantee or warranty regarding the files.
