Update 1

Edit Description: This data was developed from April 2009 digital imagery using stereo compilation. The imagery was flown in color and at an altitude necessary to produce a 15 cm pixel resolution dataset. Planimetric and topographic data was collected using photogrammetric techniques and final coordinate values were captured in MD State Plane NAD83 Feet and NAVD88. This data was converted to GIS geodatabase format.
