Houston Engineering helped the Wabasha County Highway Department collect survey data of a stretch of roadway in a steep and heavily wooded area with drone-based LiDAR.
Wabasha County Survey Using Drone-Based Aerial LiDAR
Background
The Wabasha County Highway Department has nearly 15 miles of roadway coming out of the St. Croix River Valley. Many of these roadways are too steep and/or too heavily wooded to benefit from traditional LiDAR survey.
The Wabasha County Highway Department asked Houston Engineering, Inc. (HEI) to help explore an alternative method to achieve the survey data that they need for future roadway repairs.
The Project
HEI determined that traditional survey methods were difficult and even dangerous. However, by using drone-based aerial LiDAR, accurate data could be gathered with a fraction of the effort.
This type of survey can be completed with extreme accuracy and even with heavy tree coverage once leaf-off conditions are met in the fall through the spring. Additionally, using drone-based aerial survey methods equates to more cost-effective and efficient deliverables.
Thanks to the use of drone-based aerial LiDAR, the Wabasha County Highway Department will receive a product that is usable in a CAD environment at a cost and within a timeline that would not be feasible otherwise.
Client Benefits
- Quick and cost-efficient deliverables.
- An accuracy of survey data that would be difficult to obtain through traditional surveying methods due to the topography.
