MD iMAP: Maryland Forests - Forested Buffers

Metadata Updated: July 23, 2021

This is a MD iMAP hosted service. Find more information at The dataset displays the presence and absence of forested areas within a 100 foot-buffer of a stream or waterbody. The National Hydrography Dataset (NHD) stream layer developed by the United States Geological Survey was buffered 100-feet on each side of the stream centerline to determine stream buffers in Maryland. A shoreline file developed by the Maryland State Highway Administration was buffered 100-feet to determine the shoreline buffer in Maryland. The resulting buffer layers were clipped with a forest cover layer to determine the presence and absence of forest in those buffers. The forest cover layer was derived from a tree canopy layer developed by the Community College of Baltimore County - Catonsville - Geography Department. The tree canopy was developed using 2007 National Agriculture Imagery Program (NAIP) color infra-red 1-meter imagery. To determine areas forested - contiguous areas of tree cover less than 1 acre were removed from the dataset and then used for clipping the stream and shoreline buffers.Feature Service Link: 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.
