Land Surveys (Australia) and Multi-Sensor Data Fusion

Land Surveys, a RIEGL user, was recently featured in an article released by Spatial Source where their company and the team at C.R. Kennedy, a RIEGL distributor in Australia, highlight how the RIEGL VMQ-1HA mobile laser scanning system and RIEGL UAV LiDAR miniVUX-1UAV unmanned laser scanner collaborated together for a customer’s project and do most of the hard work for the survey team.

“Land Surveys team invested in two powerful RIEGL scanners that prepared the firm for just this sort of situation. Because the customers were aware that we have both the RIEGL MLS and the RIEGL UAV system, they tend to call on us when they need sort of an infill on top of the mobile laser scanning data,” says Matt Chapman, National MLS Coordinator with Land Surveys.

“Once we selected the RIEGL VMQ-1HA MLS system, we saw this UAV and that it has the same package, the same integration and same inertial sensors.” Land Surveys CTO, Bruce Baker, said the lightbulb moment came when the team at C.R. Kennedy demonstrated just how seamlessly RIEGL were able to integrate the two systems to create a smooth, unified workflow.” With the advanced mobile mapping technology that is in the RIEGL VMQ-1HA: the scanner is able to gather all required data point measurements in one pass, therefore eliminating the need for additional mobilization costs.

The Land Surveys team strapped a RIEGL VMQ-1HA to their vehicle and were able to successfully survey the highway at 60 km/h.  They were able to stay safe and in the cool air-conditioned car while the state-of-the art scanner collected the necessary data they needed for their project. Additionally, when Land Surveys realized that the miniVUX-1UAV could be integrated together, they saw how the systems paired together were perfectly suited for transport corridor mapping. The mobile LiDAR unit offers numerous advantages over conventional ground surveys. This new age, non-invasive method of surveying can be operated day or night, with resourceful acquisition of millions of 3D design points per minute. Then once paired with the UAV scanner, the team at Land Surveys was able to obtain data from areas that the mobile unit is unable to access where the miniVUX-1UAV was able to take over and provide additional information that would later be merged together to form a new smooth dataset that could be delivered to the client. “Both systems provide a unique point of view at the point of capture, but experience shows that there are always gaps in the MLS data due to obstructions, change in slope, and where the vehicle on which the MLS is installed cannot access. What one system may miss while collecting the data, the other will be able to fill in the necessary holes.”

“There is no question that we are technically demanding now, which is typical in Australia in general,” Baker says. “But, having RIEGL and CR Kennedy on our side allows us to really push the system to the limit.” “I think that it’s certainly the future of certain types of surveying,” adds National MLS Coordinator Matt Chapman.
