2ft_Topo_Line2013
Lidar derived topographic elevation contours at 2ft Intervals from aerial lidar collected in year 2013 at 1 Pulse Per Meter. All data processing in Esri ArcGIS environment. Raw lidar point cloud data converted to to LAS dataset, then filtered for gound points only. Ground lidar converted to raster Digital Elevation Model (DEM) at 4ft cell size for Sandy Springs. Contour tool (Spatial Analyst) performed on DEM for 2 foot intervals, then clipped to lidar tile boundary. No smoothing or hydro flattening performed.
