Yellowstone River LiDAR Mapping Project
Track: Water Resources
Author(s): Jim Robinson, Doug Jacoby

Since the 1996/97 floods, significant scientific data has been generated for the Yellowstone River floodplain. These technical studies are sponsored by the Upper Yellowstone River Task Force and the Yellowstone River Conservation District Council. Data is available through a variety of Internet portals maintained by NRIS at the Montana State Library. This data was created as part of an interdisciplinary planning study to support hydraulic, geomorphic, biologic and socioeconomic analyses of the stream corridor ecosystem.

This project combined LiDAR and bathymetric surveys producing continuous elevation models of in-channel and over-bank surfaces suitable for hydraulic floodplain analysis. The project covered more than 295 square miles of floodplain and 130 river miles of active channel and included color digital orthophotography, surface models, and planimetric features. This presentation will focus on the methodology and procedures used on this project as well as discuss the many applications that the data is being used for.
