LiDAR Lunch and Learn Seminar – GITA

LiDAR Lunch and Learn Seminar

You are invited to a LiDAR Lunch and Learn Seminar presented by the Carolinas GITA Chapter. The seminar is a high level overview of current LiDAR technologies including both aerial and mobile-based systems. The seminar is designed to give the audience a firm understanding of how LiDAR works and potential applications. LiDAR is quickly becoming a valuable tool in the day-to-day operations for utilities, telecommunications, engineering and government agencies. Join us and learn how this technology may be able to drive value and efficiency into your organization. Lunch will be provided.

When accuracy matters…

Sanborn Mobile Mapping solution couples cutting edge technology with experienced and skilled staff which provides the best value and a superior product.

Derived surface model with extracted transportation and utilities features

Sanborn Mobile Lidar Collection of Island in South Pacific

Sanborn recently returned from the South Pacific with our Lynx Optical mobile terrestrial LiDAR sensor.  With a collection that took about 2 weeks, resulting in extremely high density point cloud data near 3500 points per square meter.  A total of 5 major villages with nearly 10 linear miles.  Both LiDAR data and RGB images, soon to be stitched into geo-referenced image sequences allowing for sophisticated extraction and modeling to be used for various end uses.

Remote Sensing for Coastal Management – NOAA CRC

The Coastal Resource Center – CRC has developed a valuable informational website. The CRC is part of the US National Oceanic and Atmospheric Administration – NOAA. As the name implies their focus is on research in the coastal regions where they have established an outstanding track record.

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.
