20260706 16415700 1.0 TRUE 100 ft Contours 2018 Lidar 100ft contours derived from the 2016 LIDAR flown over the valley and Logan/Blacksmith Fork Canyons. The DEMs from the state were combined using GDAL into one GeoTiff that was then smoothed using mdenoise with values of n=50, t=0.60, and v=50. 5ft contours were created with gdal_contour in EPSG:3560 and then reprojected into a feature dataset with a projection that matches the rest of the county's data. The 100ft contours were subsetted from the original 5ft contours. Data: Utah AGRC. Processing: GDAL and custom smoothing script by Jake Adams
