Geometry Type: esriGeometryPolyline

Description: Ground features were used to enhance the lidar where needed to create 2 foot contours according to ASPRS Accuracy specifications. Contours were produced from a contour keypoint terrain with breaklines enforced from ground lidar data. The Contour data has Index Contour, Intermediate Contour, Index Depression Contour, Intermediate Depression Contour, Index Hidden Contour, Intermediate Hidden Contour, Index Hidden Depression Contour, or Intermediate Hidden Depression Contour. The Contour data was subjected to manual quality control review by Sanborn including checking for tile edge matching, dangles, and topology. Edge-matching was done between Montgomery and Prince George's Counties. The lidar capture was composed of 18 separate flight missions on 13 separate dates. The dates are as follows: 20161112, 20180208, 20180208, 20180209, 20180217, 20180217, 20180220, 20180220, 20180221, 20180228, 20180228, 20180305, 20180305, 20180306, 20180408, 20180411, 20180413 and, 20180420. Created in NAD 83/91 US HARN, projected to NAD 83/91 US Feet and NAVD88 Feet.
