Process step
Description
Terrain, DEM, and 1ft Contours:For the Bare Earth Data, the Lidar Data was converted to a Multipoint feature class, with a filter for Ground (class 2). Breaklines were created for hydrographic features and the collection boundary. All hydrographic features, including water bodies and streams were delineated from the lidar data. Elevation values were conflated to the lines at 4ft intervals from the lidar data using QCoherent’s LP360 software. Elevation values for the water body polygons were added as an attribute to the feature class based on the minimum lidar elevation value along the shoreline of the water body. The multipoint feature class, water bodies, hydrolines, and boundary were used to create a bare earth terrain for the collection area. The terrain was converted to a DEM with 5ft cell resolution. The DEM was used to create the 1ft tiled contours. The contours were edited in the following manner: Lines shorter than 20 ft were deleted, looped contour lines in water ways were deleted, the shape of contour lines along the edge of water ways were edited where the lines wove more than half way across the waterway, contour lines in water bodies were checked and deleted if loops occurred within the water. Attributes were also added for 10ft, 20ft, and 50ft Index contours. A Lidar Tile Index Feature Classe was also created for the original lidar files. A Hillshade was created using default illumination parameters in ESRI software.
