Title: Growing Canada’s Next Earth Observation (EO) GenerationCanada has a proud history in Earth Observation, supporting a strong export industry driven on EO imagery and geospatial analytics. It is incumbent on all of us to continue Canada’s strong presence in the global EO community and we can only do that with a concerted effort and plan to grow the next generation of leaders. After 51 years of leadership in space and spatial information technology MDA was recen...

In recognition of the increasing costs and risk due to flooding, the Government of Canada is investing in flood mapping as part of the Government’s commitment to build safer and more resilient communities. Flood maps are critical for the public to understand their flood risks, and the availability of up to date flood hazard maps are key to strengthening the resilience of Canadian communities to overland flooding. Natural Resources Canada (NRCan) has been working in collaboration to advance...
The key elements to take into account a successful implementation of drone survey with a mm accuracy are: Know your camera; Trust your measurement; Control your space; Understand your photogrammetry software. Working out that, we present this nuance including special tags around the surveyed object as the measurement system to get details.A correct implementation of photogrammetry tags with consumer grade measurement devices and consumer grade UAVs and cameras enables very precise a...
Title: DEIL experiments and outputs with open geospatial dataThe Data Exploration and Integration Lab (DEIL) at Statistics Canada has implemented a number of projects using, to the extent possible, open georeferenced data and open source tools. This presentation outlines some of this work. We will present recent developments of the Linkable Open Data Environment (LODE), examples of the use of LODE data, the development of a Proximity Measures Database and Data Viewer, and an R&amp...

The government of Alberta manages the production of riverine flood studies under the provincial Flood Hazard Identification Program, to assist communities in keeping Albertans safe and protecting their properties from floods. Flood maps improve public safety, support emergency management, and help us build safer and more resilient communities. The government of Alberta also manages the production of alluvial fan studies to help Albertans learn about flood risks in the steep terrain of Alberta...

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...
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...
With drones like the DJI Matrice 300 now being positioned using RTK GNSS, combined with Structure from Motion (SfM), high precision mosaics are possible without deploying targets. The ability to mount lidars (DJI L1 and L2) and other optical sensors (RGB, multispectral, thermal) allows for precise surveying and the production of high resolution and high accuracy mosaics with minimal ground control. While battery power still remains an issue and the limiting factor for flight duration (10’s of...
Dillon was retained by the Government of Nunavut to perform a Needs Assessment for the rehabilitation of the Runway 13-31, Taxiway A (Alpha), Taxiway C (Charlie), Apron A, and Apron C of the Rankin Inlet Airport.The project included pavement rehabilitation and geotechnical investigations for Runway 13-31, which is a 6000’ x 150’ asphalt paved runway, along with Phase I ...
As the drone industry is increasingly focuses on developing larger airframes and equipping them with bigger sensors, Spexi is taking a revolutionary approach to aerial imagery. At Spexi, we believe that the future of geospatial data collection lies not in size and complexity, but in numbers and standardization. The Spexi platform leverages the power of crowdsourcing, deploying local pilots with small drones to capture standardized imagery across entire cities. This method allows us to achieve...
With the increasing focus on damage prevention, public safety concerns, and environmental damage due to underground utility strikes, it has become more critical to accuracy locate, store and be able to visualize subsurface utilities. Several key technical details are discussed when implementing a subsurface mapping system from data collection to the use of machine learning for 3D modelling and visualization. The ability to make safe and effective decisions for i...
Earth Observation technologies have experienced unprecedented innovation and accessibility over the past several years. The role of the commercial sector has stepped in to offer several capabilities historically only available from government. This session will focus on examples of how EO technology is being...
Reduced snowpack in the Rockies presents a severe drought risk for Southern Alberta. Mountain snowmelt in the Bow and Oldman basins maintains reservoir levels, crop irrigation, municipal and industrial supply, and ecosystem services. As climate and consumption pressures increase, accurate snow water equivalent (SWE) data is crucial for water supply forecasts, which impact allocations and emergency drought measures. Field snowpack monitoring does not provide accu...
