Name: Contours

Display Field: FCode

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: This set of 1-foot contours were derived from a 2014 LIDAR DEM flown for the state of Delaware using a modified version of the USGS Contour Derivation algorithm detailed by Arundel et al. (2018). Details for the LIDAR flight may be found in the report by Quantum Spatial (2015). Contours are indexed at 5-foot intervals and classified as “Normal” or “Depression”. Contours are projected in Delaware State Plane NAD83 (2011) meters and the vertical datum of the source DEM was NAVD88.
