Lake Tyrone Shoreline LiDAR Scanning

This project involved the collection and processing of 2.5 miles of mobile LiDAR data and 360-degree imagery to support the design of a new sanitary sewer project around Lake Tyrone. Spicer Group’s survey professionals used their Leica Pegasus: Mobile Mapping System mounted on an 18-foot boat to collect the data and process it all in the same day. The portability of the system provided a unique opportunity to use a boat to collect the data from the lake and keep ground survey crews out of lakefront owners’ yards. Some key points to consider regarding this project include the following:

All features were surveyed from the office which increased efficiency and reduced interactions between ground personnel and residents living within the project limits. 

• Two identical passes were made around the lake to collect the data, and the unadjusted difference between the LiDAR data was less than 2.5 cm.

• Extraction of all visible features up to house fronts was completed in one week.

• All features were collected within the visible range of the LiDAR, so if any additional features needed to be extracted for design, no further mobilizations to the project site are necessary.
