Light Detection & Ranging (LiDAR)

 

what is lidar

LiDAR measures distances by sending pulses of laser light that strike and reflect from the surfaces of the earth.  The measured times are converted to distance.

LiDAR generates very large datasets- it is not uncommon for the system to collect 50-100 thousand positions (or more) per second.  The data can be post-processed to provide highly accurate and detailed digital elevation models (DEMs), topographic maps, vegetation heights, and more.

LiDar derived water layer

The GIS team at TCD is working to create a water layer of rivers, streams, ditches and water bodies derived from the 2015 LiDAR dataset acquired by Teton County.  This layer will provide Teton County with a spatially accurate water layer at a scale of 1:1000. This layer will have the most comprehensive collection of names sourced from the National Hydrography Database, Bridger Teton National Forest water layer, Wyoming State Engineers Office and Teton County public planning and building records. It will serve as a resource to TCD, county staff, water specialists, environmental consultants, homeowners, and other user groups reliant on the Teton County Mapserver.
