Description: Ayres Associates provided Vilas County, Wisconsin, with lidar based topographic mapping services in 2013-14. The LiDAR data was collected on May 13-17, 2013 using a Leica ALS 70 sensor mounted in a fixed-wing aircraft. LiDAR data was collected to support to support the generation of 2-foot contours to FEMA vertical accuracy standards. The LiDAR data was delivered according to a 5,000 foot x 5,000 foot tile schematic. The LiDAR data was calibrated using information collected at the time of flight from GPS base stations on the ground and airborne GPS/IMU in the aircraft. The calibrated LiDAR data was processed to a classified point cloud, bare earth DTM, DEM, DSM, contours, breaklines, and intensity images. Vilas County is located in north central Wisconsin and is bordered by the Upper Peninsula of Michigan along its northern boundary. The County is characterized by a high concentration of inland freshwater lakes and mixed northern forest. The confluence of the Eagle River and Wisconsin River is in the city of Eagle River, which is the county seat. The total project area is 1017 square miles.

Description: The Vilas County lidar project area covers approximately 1,027 square miles, which is countywide including a buffer around the county boundary. The lidar data was acquired by USGS as part of the 3DEP program at an average nominal point density of 8 points per square meter. Lidar data was acquired in spring 2022. Vilas County procured enhanced and derivative datasets from the USGS lidar. Project specifications are based on Vilas County requirements and on the U.S. Geological Survey National Geospatial Program LiDAR Base Specification, 2021 Revision A. The data was developed based on a horizontal projection/datum of NAD83(HARN) / WISCRS Vilas (ftUS) (EPSG Code: 7399), and vertical datum of NAVD88 - Geoid12B (Feet).
