Using drone lidar to complete an As-Built survey
Spatial Data Consultants provides their drone surveying expertise to complete an As-Built SurveyRome, NY, )
“Down to Earth” is a documentary-style reality series that shows how real surveyors collect data and turn it into real deliverables, despite challenging conditions, hidden dangers, and inclement weather.
In this 1st episode, Mark Schall, Owner and Chief Professional Officer at Spatial Data Consultants explains how the company has transitioned from using manned fixed wing and helicopter aircraft to drone surveying systems. “Initially the company was based off traditional photogrammetry using fixed wing and helicopter aircrafts,” said Schall. “We’ve now transitioned into drone and UAS systems for all of our Lidar and photogrammetry. The one thing we pride ourselves on is the level and competence and expertise we have in our personnel, like Fred Johnson, our current director of UAS Services.”
The episode continues with a brief analysis of a previous drone LiDAR point cloud created by SDC, before Fred walks through the planning process for an As-built Survey they will conduct with drone LiDAR for the new entrance at High Point University in North Carolina.
Episode 2 sees the SDC team set up and fly a corridor surveying mission at the new entrance to High Point University. “We decided to do a corridor mission because the main focus was the new roadway leading into the campus,” explained Johnson. “I expect all of the details needed for the As-Built Survey to be clearly visible in my point cloud and photography.” Utilizing the mdLiDAR3000 from the Microdrones expert drone line, SDC will be able to deliver the planimetrics, topographical features and other construction structures to make sure that all of the improvements on Panther Drive were constructed in accordance with the original design specifications. However, during the As-Built Survey, the team ran into some unanticipated challenges in ground traffic and an open road-way.
The third episode takes place back at the office of Spatial Data Consultants, where Fred processes the data to visualize the utilities, structures, and other construction features of the project in a LiDAR point cloud. Using mdInfinity, a complete software solution for Drone LiDAR, and other 3rd party software, Johnson will see if he can successfully create the As-Built Survey and deliver the project.
The series concludes with the fourth episode set in a local bottle shop, where the team reviews the project, workflow, and shares their final thoughts and insights all while enjoying a cold beverage.
