What Can I Do with My LiDAR Data?

The following is an example of products derived from LiDAR including Contours, Line work, elevation data and additional classification. The data was used for a transmission project. In addition to the LiDAR data digital Imagery was captured on the same platform using a Medium format DSS 439 Camera. A brief write up on the project is also provided below.

Transmission Mapping – The provider employed a LiDAR/digital camera coupled sensor for transmission mapping. The system can be mounted in either a fixed wing or helicopter platform to provide an array of products. Recently, The provider collected a forty linear mile transmission corridor using a fixed wing platform. The LiDAR data was collected at an average density of forty points per meter and RGB digital imagery data using a DSS 39 megapixel camera at less than 4 inch pixel resolution. The data was collected in two 4-hour missions using a twin-commander aircraft flying at 500meters AGL. The data was processed and delivered in 2 weeks. The products included classified LiDAR in PLScadd format including road, water bodies, drainage, man-made structures, distribution, transmission, and substation to name a few. Additional products included, two foot contours, line work, Ortho-imagery and surveyed information. The resulting vertical accuracy of the LiDAR data as checked against the ground survey is 4.23 cm RMSE. The horizontal accuracy was 10- 25 cm RMSE as checked against the ground survey. The data is being used for planning new line construction, permitting, environmental impact assessment and vegetation management. Addition uses include sway and sag analysis.
