This data illustrates parcels subject to some type of preservation easement as well as properties owned by federal, state, and local governments. In addition, properties owned by local land trusts and private conservation organizations such as The Nature Conservancy are included. Conversation easements include easements from the Maryland Agricultural Land Preservation Foundation (MALPF), Rural Legacy, Forest Legacy, Maryland Environmental Trust (MET), county and state purchases of development rights, transfers of development rights, open space from home owners associations, local open space requirements, and private conservation easements. This data is complied from settlement data directly from conservation program administrators, county GIS updates on preservation activities, and public available data from the Maryland Department of Natural Resources. In addition, this data is in the process of being realigned to the 2012 IMAP parcel polygons. The realignments at available on a county by county basis depending on the production schedule.

This dataset consists of land areas that are run and maintained by U.S. Governmental authorities. These files were created for planning purposes and should not be used as a definitive source of mapped data for any of the associated types of land ownership. There have been intentional omissions due to sensitive data types and in some cases, the source documents cannot be considered complete. The Federal Lands data layer was updated to show the most current known lands presently owned by the Federal Government. The sources of the updates came from several sources (the US Park Service, Maryland Department of Planning, MD Property View, ed. 2005, etc.). Ownership status was checked over parcel boundaries and known property records for completeness and accuracy. US Postal properties were not included in this data set.

These ESRI shape files are of National Park Service tract and boundary data that was created by the Land Resources Division. Tracts are numbered and created by the regional cartographic staff at the Land Resources Program Centers and are associated to the Land Status Maps. This data should be used to display properties that NPS owns and properties that NPS may have some type of interest such as scenic easements or right of ways.

This polygon feature contains parcels containing Federal interests in private land, including easements and reservations (1) in which the Federal Government does not have a fee title interest; and (2) that provide both legal public recreational access and legal administrative access to the Federal land in conformance with the MAPLand Act and the PLAD project. This dataset also also provides BLM managers with information to identify access limitations, vulnerabilities, and areas where access to public lands may be improved. The dataset can also support additional management of resources such as timber harvest, travel and transportation planning, wildfire fuels reduction projects and many other land management related decisions.
