These aerial photographs were taken and compiled by the Farm Service Agency and made available through the U.S. Department of Agriculture. Maryland Environmental Service GIS on behalf of SHA attained the files from their sources, georeferenced each file using ESRI ArcGIS Pro to modern imagery using landmarks or coordinate tic marks if provided, and quality controlled for accuracy. Files were then compiled into a mosaic for complete area coverage as available. This map is matched to modern geography as closely as possible based on the limitations of the original document and available imagery.</span></p></div></div></div> MD iMAP, MDOT SHA, Farm Service Agency, US Department of Agriculture MD_USDA_57 MD Historical Imagery MDOT SHA <div style='text-align:Left;'><div><div><p><span>The Spatial Data, and the information therein, (collectively the "Data") is provided "as is" without warranty of any kind, either expressed, implied, or statutory.
