Upcoming ARCH NZ Event:

WEBINAR: SH1 Dunedin – How many scanners does it take?

In Dunedin, SH1 provides a unique situation where it splits into two one-way systems, both classed as National level (i.e. high-level) roads. The speed limits range from 50-80km/h which poses significant risks to field crews and equipment.

Patersons was engaged to survey 7km of SH1 within Dunedin city and it needed to be completed quickly. During initial survey planning, traffic management cost estimates quickly skyrocketed and risked cost overruns, forcing a rethink of the plan.

The final solution integrated survey data from many sources, minimising the need for surveyors to access the road corridor on foot. This webinar will take you through the workflow to combine mobile, terrestrial, and kinematic scanning technologies to meet our client’s requirements.

PRESENTED BY: Matas Barakauskas, Senior Surveyor at Patersons.

Past ARCH NZ events available to watch on-demand:

WEBINAR: Combining underwater sonar and MLS data for topographic survey outputs

Mark and Kirsty will provide a comprehensive overview of the entire field to output workflow, detailing each step involved in capturing and processing CHC NAV Apache Sonar data.

They will demonstrate how the data is combined with laser scanning for precision, and processed using Leica Cyclone 3DR to produce detailed outputs.

These outputs not only highlight underwater features but also provide a wealth of surrounding information, offering a complete picture of the surveyed area.

This particular example is drawn from the Whanganui River, showcasing the practical application and effectiveness of these technologies in real-world scenarios.

PRESENTED BY: Mark Green and Kirsty Mackie

WEBINAR: A deep dive into drone LiDAR Systems 

Following on from one of our most popular ARCH Webinars, Drone Photogrammetry vs Drone LiDAR, this session will take a deep dive into two popular LiDAR payloads available for drones. 

Once a technology beyond the means of most companies, the LiDAR systems available for drones today are compact, lightweight, and affordable. Surveyors and other spatial professionals can now leverage the significant benefits these systems offer including the ability penetrate vegetation and measure an accurate ground surface. 

This webinar will compare two popular LiDAR systems compatible with the DJI Matrice 300/350 drone; the DJI Zenmuse L2 and the CHC Navigation AlphaAir10, with focus on workflows, accuracy, precision and vegetation penetration. 

PRESENTED BY:  Lennon Bedford - Technical Specialist and Christchurch Branch Manager at Global Survey.

WEBINAR: Quantifying rockfall erosion and drivers in a valley with rapid glacial retreat using UAV-mounted LiDAR and in-situ monitoring.

As mountains warm and glaciers retreat, glacial valley walls become destabilized, leading to periods of increased rockfall activity. Repeat UAV-mounted LiDAR surveys on the valley walls of Fox Glacier are combined with regional LiDAR datasets to monitor changes in topography and identify the spatial patterns of rockfall along the retreating glacier. The data will help to assess how rockfall patterns link to the processes driving rockfall.

This talk will discuss the methods used to capture the UAV-mounted LiDAR data, from planning to outputs, challenges faced and overcome, including tectonic movement and UAV restrictions, and the initial findings within the wider context of deglaciation impacts globally.

PRESENTED BY: Jason Farr, Engineering Geological Surveyor at GNS Science

WEBINAR: Merging Technologies - 3D Printing, Robots and Reality Capture

Marcus Hall introduces a remarkable robot designed to survey environments too dangerous for Surveyors. It addresses a longstanding issue in surveying: how to conduct a survey without being physically connected to the equipment.

Marcus's journey, starting with a simple solution involving rope, wheels, wood, and mini prisms, led to the creation of Pipe-i, a cutting-edge robot with exciting future prospects. In his presentation, Marcus will share the trials, tribulations, and innovative path that led to this remarkable technology.

PRESENTED BY: Yannick Stenger – Product Manager at Leica Geosystems

WEBINAR: New Options for Scan to Plan (and BIM) for Surveyors

Scan to BIM/Plan is a well understood concept but still quite laborious. There are multiple approaches depending on the complexity and scale of the building being scanned.

This session shows a new approach within BricsCAD to easily create geometry from the point cloud in 3D and then process to 2D outputs. We will start with a very simple building and progress through some more challenging cases in terms of the geometry and the outputs.

PRESENTED BY: Sean Twomey, Senior Solutions Consultant, Bricsys / Hexagon

WEBINAR: Laser Scanning Tips and Tricks – From field to QA/QC

In this webinar our presenters, Kirsty Mackie and Lennon Bedford from Global Survey will discuss  various tips and tricks related to laser scanning, from field capture to quality assurance and quality control (QA/QC) of outputs. It will provide guidance on how to improve the final quality of outputs by employing certain techniques during the field capture process. The webinar will focus on the Leica laser scanning solution, however, the higher level overview of quality assurance and control steps covered in the webinar will be applicable to other laser scanning solutions as well. Overall, this webinar will provide valuable insights and practical tips for improving the quality of laser scanning outputs.

PRESENTED BY: Kirsty Mackie - Reality Capture and Autonomous Survey BDM, Global Survey & Lennon Bedford - Technical Specialist, Global Survey

WEBINAR: Drone Photogrammetry vs Drone LiDAR

Often there is an assumption that LiDAR is better than photogrammetry, but is this always the case? This webinar will compare differences in capture, processing and quality of drone photogrammetry and drone Lidar. Different sensors often mean different outputs and applications, so we will explore the capabilities of each.

Photogrammetry data from a DJI Mavic 3E drone is compared with LiDAR data from a DJI L1 LiDAR carried by a DJI Matrice 300. Leica P50 terrestrial laser scanning data is used for independent checks / comparison to both drone data sources. This webinar will also look at the full workflow from field to finish, showing data processing and end analysis/ outputs. 

PRESENTED BY: Lennon Bedford - Technical Specialist, Global Survey

WEBINAR: How To Quality Assure Point Clouds

Reality Capture is, and has always been, what Surveying is all about. UAVs and TLS devices are globally becoming extensions of the Surveyor’s toolkit. This webinar focuses on dispelling some myths about laser scanning, namely that laser scanners are just ‘point and shoot’ and that ‘all point clouds are the same’. As lots of non-surveyors pick up these tools a key point of differentiation from a Surveyor’s point of view is accuracy. This webinar will be a technical overview of laser scanning field workflows, and error identification in the final output point clouds

PRESENTED BY: Kirsty Mackie - Reality Capture and Autonomous Survey BDM, Global Survey

WEBINAR: GIS and Reality Capture Visualisation

Part 3 of our GIS series is a higher-level overview, by our very own Kirsty Mackie, on where Surveyors and GIS professionals come closer together – visualisation. GIS is fundamental to many Digital Twins. We will look at the importance of visual communication for asbuilt conditions and engineering design, some common workflows, issues and potential with GIS and point cloud data

PRESENTED BY: Kirsty Mackie - Reality Capture and Autonomous Survey BDM, Global Survey

WEBINAR: FME and Reality Capture Data

FME can read and write to 100s of different formats. This provides the capabilities to utilize LIDAR derived data alongside a variety of spatial and nonspatial data to provide fast and effective results.

In this webinar we will take a closer look and have an in-depth overview of some of the LAS Tools utilized within FME for the processing of Las data.
