5 Reasons to select Routescene for your drone LiDAR system

Posted on April 29, 2021 in Accuracy

We understand it can be confusing when comparing the various UAV/ drone LiDAR systems available on the market to choose the one that’s best for you. Of course, it is important to compare and contrast the different technical specifications, as different requirements need different levels of accuracy, resolution and range. But how do you compare beyond the technical specifications to make your choice?

Customers tell us that the ability to access difficult terrain and produce high-resolution results quickly and effectively are key drivers for the adoption of the Routescene UAV LiDAR system. The advantages of our proven system are:

1. Superior vegetation penetration capabilities
2. Quality Assurance in-built
3. End to end solution saving you time and improving productivity
4. Confidence – reliable, proven products from experts
5. Comprehensive training and technical support

Interested and want to know more? Here’s our explanation and evidence for each Routescene advantage:

1. Superior vegetation penetration capabilities

The vast majority of survey and mapping projects require a Digital Terrain Model (DTM) to be achieved through vegetation or there is a need to identify and profile individual trees within forestry and woodland. How do you collect data through vegetation? LiDAR is the perfect technology for this. It can penetrate through vegetation providing data on the layers and the surface beneath whereas photogrammetry only captures the vegetation canopy.

Routescene’s drone LiDAR system excels at penetrating dense vegetation. First, let’s look at the hardware. The carefully selected array of sensors, which includes the Velodyne HDL-32 LiDAR scanner, enable this powerful performance. The Routescene UAV surveying system provides a much higher capability to penetrate dense vegetation than other drone LiDAR systems, for example, those incorporating the Velodyne Puck (VLP-16) or Quanergy M8. This is due to the number of lasers and the scan rate of the HDL-32. With 32 lasers, in dual return mode it achieves up to 1.4 million points per second, 2 to 3 times more than lower specification LiDAR sensors. The result is a very high-density point cloud, achieving up to 400 points per sq/m on the bare earth through dense vegetation, which delivers high-resolution feature definition in the final output.

Now let’s consider the Lidar data processing software. Processing the huge volumes of raw LiDAR data captured can be a time-consuming task. Routescene’s drone mapping software, specifically developed to process, analyze and visualize 3D spatial data, offers an impressive toolkit to create outputs such as DEMs, DTMs and DSMs quickly and easily. For example, in one step with our automated “Bare Earth tool,” you can remove all non-ground points and reveal the ground surface.

Use case: Finding ancient dwellings through dense vegetation

Identifying undiscovered 750-year-old structures in an ancestral Pueblo at Sand Canyon, Colorado, USA was a highlight of this project. Unseen to the naked eye, the Routescene drone LiDAR system, penetrated dense vegetation to show the Pueblo was more extensive than previously known.

2. Quality Assurance in-built

Why is Quality Assurance important? So you can verify the accuracy of and have confidence in the quality of your survey data. By implementing Quality Control across the complete survey process you will significantly increase the value of your data and your final outputs.

We’ve made it simple for you. We’ve considered every step in the process and applied our experience in Quality Assurance and Quality Control (QA/QC) so that you achieve the best accuracy possible and improve efficiencies.

Fundamental to the Routescene system and to achieving Quality Assurance is a carefully thought through 6 step workflow. Spanning survey and project planning, data acquisition, data processing to the final outputs, this workflow is a set of orchestrated and repeatable procedures and processes, so every survey and the subsequent data analysis is undertaken in a systematic, streamlined way. This ensures you achieve the best possible outcomes, which are validated, every time.

 

Specific Quality Assurance features built-in to this workflow include real-time in-flight monitoring of the data being collected during the entire drone survey using our QA Monitor application; UHF radio telemetry to ensure real-time QA is reliable even when a long distance from the Ground Station; our desktop-based data processing software is field-deployable (no need for internet access/cloud data upload which can be difficult in the field) to enable preliminary inspection of the raw LiDAR data on-site; specially designed Ground Control Targets for boresight alignment and to determine absolute accuracy, and finally you can automatically generate a Quality Assurance Report to ASPRS standards to verify your results.

3. End to end solution saving you time and improving productivity

Integration of the component parts of a drone LiDAR system takes time and money, it’s a complex task requiring specialist knowledge. Our end-to-end solution is literally that. We’ve thought through everything so you don’t have to. It’s tried, tested and ready for immediate use. Let’s take a closer look at what’s included…

a) The hardware suite

The robustly engineered 3D mapping sensor, the Routescene LidarPod, is a self-contained unit including an internal GNSS/INS, data storage and radio telemetry. It is portable, easy to deploy, it eliminates user error as there is no assembly, and the minimal number of external connectors significantly reduces the risk of failure.

Our Ground Station transmits RTK corrections to the LidarPod and logs the data for subsequent post-processing; you can opt for our Ground Control Targets to establish ground control; Pelican cases to protect the equipment during transportation.

b) UAV integration

Designed for easy integration on any rotary UAV capable of lifting a 3.3kg payload. The lightweight carbon fiber vibration-damping mounting kit has been specially designed to reduce vibration from the UAV and for ease of use.

c) The software

Data processing is the biggest challenge of any LiDAR survey and efficient data processing is crucial to deliver results in a timely and cost-effective way. Unfortunately, most GIS and CAD packages are unable to cope with the sheer volume of data collected, resulting in data cleaning and analysis being performed across a number of software packages. This has a consequence – every time you convert and export a file not only does it take time but you lose information. It’s expensive purchasing and becoming familiar with the many different software packages too.

Routescene’s processing software removes these problems. Using the rich toolkit of pre-developed filters you can clean and analyze all your raw LiDAR data in one software package. You achieve a really clean dataset and keep the quality and resolution of the data. You can create repeatable workflows to ensure consistency, to compare and contrast multiple datasets and repeated surveys over time. With this consistency, you can measure quality.

d) Even the tool kit is included

Have you ever experienced delays to projects through basic tools missing or parts failing and you have no spares? We’ve thought of everything you can possibly need to keep your project on schedule.

e) Conversion for mobile mapping

To maximize the use of your UAV LiDAR system you can transform it into a Mobile Mapping system with our vehicle upgrade kit.
