Geodetic Reference Systems are the foundation for geospatial data, serving as the official reference for latitude, longitude, height and gravity in Canada. There are many contributors to providing such standards to Canadians, including Federal, Provincial and Municipal governments, the private sector, academia, and others. Users will know that every few years there are new versions introduced of the datums or reference frames. A change in reference system, however, invo...

Wetlands are important to water quality, nutrient cycling, and biodiversity, and have been identified as a management priority across Canada. Reclaiming wetlands that have been impacted can be a long-term, costly process depending on the type of wetland, location, and potential access constraints. One challenge with wetland reclamation is that the work may cause additional or new wetland impacts during access and execution of the work. Concurrent with wetland reclamation priorities, there ...
How do you decide when to mobilize and when not to, or even where can you safely and legally fly. As the frequency of unpredictable weather and forest fire smoke increase, so too does the risk in mobilizing to a job site. This presentation will demonstrate OGL Engineering’s process and different geospatial resources available to better inform your decision and minimize risks.
The talk presents how multi-band SARs (X-band Iceye, C-band RADARSAT-2 and L-band SAOCOM) support various earth observation applications, such as target identification, change and displacement detection, and soil moisture map generation. Furthermore, it presents MDA's next-generation Chorus constellation (combination of C-band and X-band SARs).
Geoff Zeiss devoted over 30 years of his life to the Geospatial industry and global community, focusing on utility and construction sectors, and mapping underground utility infrastructure among many other projects.

We explore the motivations behind the implementation of openBIM and its integral role in advancing the built asset industry. The built environment is immense and complex, it is also a huge responsibility. Our industry directly impacts it, designing, creating and maintaining it. In an era where what we all need is a better built environment, openBIM stands out as a key enabler. Together we will imagine a future where our industry works more effectively, efficiently and with more c...
Building Information Modeling (BIM) is transforming the built asset industry, yet firms of varying sizes—large, medium, and small—adopt BIM in distinct ways tailored to their unique resources and project demands. This session will explore BIM’s origins, current applications, and future directions as shared by representatives from three different firms. A significant focus will be on the importance of data integrity and governance, particularly as Artificial Intelligence (AI) becomes increasin...
The session will focus on considerations for deploying Artificial Intelligence in professional practice; identifying potential landmines and working on solutions from a privacy-first perspective. The talk will include a high-level overview that underscores the fundamental components that encapsulate an AI derived “solution” and delve into a practical, real-world example being tested on an active project.Topics Covered:• An illustrated example of BIM model query using AI• AI too...
Accurate mapping of road networks is essential for navigation, disaster response, and urban planning. Traditional methods relying on remote sensing images, Lidar data, and GPS trajectories are hampered by time-consuming manual updates and incomplete extraction due to obstructions from trees, buildings, and shadows. However, recent advancements in deep learning models have shown promise in improving road mapping and automating the detection of missing roads.This study uses a transfer le...
Construction contracts are the same worldwide. While there are differences in language, classification, project delivery and other factors, the one common denominator is that a construction contract requires Drawings and Specifications. While geometric modelling software and specification software have both evolved over time, very little effort is currently being exerted in Canada to integrate them in document development processes.According to Arcadis global surveys, the #1 cause of c...
For the last five years I have been providing reality capture services to documentary film producers. These series have included NatGeo's Buried Secrets of WWII, NatGeo's Drain the Oceans, Discovery's Expedition Unknown and Expedition Bigfoot. LiDAR, photogrammetry, thermography, magnetometry, and multi spectral imagine all provide context that professional storytellers (TV producers) crave. Join me as I share stories, successes, and failures of these unique service offerings.
The three building blocks of digital building delivery are BIM, VDC and Digital Twins. There are various definitions for these three things, but based on my experience I define them as follows:- Building Information Modelling: a model with or without 3D geometry that hosts the information about building material, dimensions, connections, forces, power, flow rates, and all other elements required in each element that forms the building. - A key subset of understanding BIM is under...
Despite the rhetoric surrounding the use of building information modelling (BIM) to enhance collaboration by connecting people and data, the status quo is to work with proprietary solutions and closed file formats, limiting accessibility and interoperability. Additionally, the increasing complexity of projects in the Architecture, Engineering, Construction, and Operations (AECO) industry requires technology that integrates data at a range of scales, from asset to city, and beyond. To address ...
In December 2023 a unique gathering of technology and talent gathered on Alcatraz to capture the entire island, inside and out, from the ground and from the air to assist the National Park Service understand the risks seal level rise and climate change present to the island. Join me and, perhaps, other members of the extended team as we share the technology, the experience, and the adventure of this unique experience.
Today, digital twins, autonomy and artificial intelligence (AI) dominate the lexicon of the geomatics industry. These capabilities provide significant productivity advantages to our profession, but our domain content and knowledge are critical to their success. These tools will change the way we work and transform the industry. However, they will not replace us, but rather change our role. This is no different than when the EDM, total station, CAD, or GPS became part of our professional lives...

This presentation details the results of a field study conducted in July in Santa Cruz, California, where thirteen participants employed terrestrial laser scanning (TLS) to assess concrete tolerance on a construction site. The study aimed to establish the precision of TLS as a test method for verifying concrete tolerance in accordance with ASTM E-691-23. Additionally, it sought to quantify the bias of the TLS method by compar...
Local governments have been updating their asset inventories to comply with the TCA legislation since the early 2000s, paying particular attention to the attributes, locations, ages and conditions of their assets. However, infrastructure changes constantly due to capital projects and land development, especially in fast-growing municipalities like Kelowna. Collecting accurate and complete information on new assets has been a major challenge, mainly due to limited staff resources. To address t...
Photogrammetry is not just limited to aerial platforms. Modern mobile devices contain high-quality cameras and increasingly have LiDAR and depth sensors built in. When combined with high-accuracy GNSS systems, these mobile devices can quickly collect accurate data for utilities, infrastructure, inspection, as-builts, construction, and more. Utilizing these readily available devices can reduce project delays, capture better documentation of utilities, and lay the foundations for digital infras...
In this year's reality capture track, we have shown you the unprecedented value of reality capture systems when adopted into high-cost, high liability and fast pace environments, some of the problems these systems are solving today, and tools to help the effectiveness and quality of those solutions.
