About Buffalo County 2017 LiDAR
In the spring of 2016 Survey Crews with Ayres Associates were in Buffalo County collecting ground truth control points in preparation for aerial LiDAR collection. The control points are used by the aerial mapping group at Ayres Associates to post process the data and to verify the vertical accuracy of the various types of ground cover that Buffalo County has.
The county was divided into 22 different areas for this survey to ensure that the data collected was spread evenly throughout the county. Each area has roughly 4-5 ground types and one horizontal. Horizontal accuracy points are also established in order to ensure that the data is horizontally accurate.
Using GPS and total station instruments the survey crews captured roughly 3-5 sites per day, depending on different variables (cell phone coverage, GPS monuments, weather, etc.). Once completed with the field portion of the ground truthing survey, the aerial mapping group with Ayres Associates flew the LiDAR capture mission over Buffalo County on March 22nd 2016.
