Project abstract summaryproject title: proposal for landslide inventory mapping utilizing change detection techniques in western northdakotaproject period: 07 15 2024 through 07 15 2025THE first north dakota geological survey landslide inventory map (about 300 1:24,000SCALE quadrangle maps) was published in 2003 during phase i of the north dakotageological surveys landslide mapping program. The landslides were delineated by handusing stereo projection of black and white 1:20,000 scale aerial photographs taken duringthe 1950S and 1960S. Phase II started around 2017 with the goal of mapping landslides forthe entire state using lidar, and now phase III is mapping active landslides utilizing repeatlidar coverages. Geologists at the north dakota geological survey calculate thedifference between the two lidar collects to locate movement and, once determined tobe a landslide, delineate the feature. This award would fund phase III in the BELFIELD1:100,000 quadrangle in western north dakota. This area contains extensive critical energyinfrastructure (oil well pads and pipelines) and encompasses a region that is very landslidedense. Mapping active landslides provides a dataset that the public, government, andindustry leaders can use to make informed decisions concerning private and industryinfrastructure installation. Alongside commercial applications, further development of ourstatewide active landslide dataset creates an invaluable asset for studying the nature oflandslide occurrence. The belfield 1:100,000 area now has multiple lidar datasets, one ofwhich is 3DEP.
