Abstract
Land Use/Land Cover data for Prince George's County, Maryland create by Maryland Department of Planning.
Purpose
To assist the state of Maryland and the Marland Department of Planning analyze the consumption of land due to new development. The main intent of this update is to capture the conversion of land from these uses to development and in the process, characterize this development.
Supplementary Information
Beginning with the 2002 Land Use/Land Cover as a starting point for the update, MDP utilized updated aerial imagery in conjunction with parcel information to develop the 2007 Land Use/Land Cover. Aerial photography collected in 2005 serves as the imagery to underlie all land use change. Parcel information from Maryland Property View 2006, in tandem with the imagery, helped to classify land use information into specific categories. Throughout the process, the 2002 Land Use/Land Cover layer was edited to be consistent with land use information presented by the aerial imagery and the parcel information. The land use\land cover classification scheme described within has been used to identify the predominant usage of land that could be interpreted from high altitude aerial photography and satellite imagery. The LU_CODE field contains a 2 or 3 digit integer number identified and defined in the attributes section. Two new categories have been added to the 2007 Land Use/Land Cover layer; very low density residential development and transportation.
