Pine County LIDAR Data and Soil Mapping
By Danielle Evans, Natural Resources Conservation Service
NRCS has contracted with The Sanborn Map Company to fly LIDAR for Pine County, Minnesota in leaf-off conditions. The flight was originally contracted for Spring 2006, but the weather conditions and leaf-off status of vegetation did not cooperate, so it has been postponed until this fall. After LIDAR is flown, the data should be delivered to NRCS from Sanborn in approximately 3-4 months. A quality assurance check will be completed and once the data has passed, it will be made available to the public. Vertical accuracy for this project is set at 37 cm or better and will have a 95% confidence level or better for creating 2 foot elevation contours.
NRCS plans to use LIDAR data for conducting the soil survey work for Pine County. It will be especially beneficial for areas with little relief, areas with topography that are difficult to traverse and areas within forested lands. NRCS intends to use LIDAR-derived DEMs to do analysis on slope, slope/shape and statistics. We will also use 3D mapping software with LIDAR data to help map soils more accurately. NRCS will use these analyses to create predictive mapping tools for soil scientists to use in the field.
