DRDC

AI Tool Development for DRDC

ASL has collaborated with Defence Research and Development Canada (DRDC) for over a decade, supporting a range of research initiatives focused on the application of geospatial analytics and artificial intelligence to defence-related challenges.

Environmental

Monitoring Salmon Freshwater Habitat in Near-Real-Time using Satellites

ASL has signed a contribution agreement with the Canadian Space Agency for a 2-year project under the Satellite Mobilization for Biodiversity (SaMBA) opportunity, part of the smartEarth funding initiative.

IDEaS

IDEaS Innovation for Defence, Excellence and Secruity

ASL contributed to the Canadian Department of National Defence (DND) IDEaS program to address challenges in space-based intelligence, surveillance, and reconnaissance (SB-ISR), focusing on detecting concealed human activity in remote regions. 

Kelp mapping

Kelp Mapping Using Satellite Imagery

Malahat First Nation and Transport Canada, initiated a project to develop methods for mapping bull kelp in the southern Gulf Islands of British Columbia using high-resolution optical satellite imagery in support of assessing cumulative effects of marine shipping. The work was performed by ASL and project partners Sarah Schroeder and Dr. Maycira Costa of the University of Victoria.

The study compared two classification approaches—object-based and pixel-based methods—to detect floating kelp beds and map their distribution across the study area. Satellite imagery was acquired and processed to develop kelp detection workflows and evaluate the performance of each approach, producing spatial datasets to support future monitoring and marine management. 

Project outputs included:

  • High-resolution maps of bull kelp distribution
  • GIS datasets of mapped kelp beds
  • Comparison of object-based and pixel-based classification methods
  • Preliminary assessment of shipping impacts
  • Plan for long term operational monitoring
  • Discussion on satellite data products for other components of the marine system (e.g., eelgrass, shoreline changes, small vessels, suspended sediment, water temperature, algal chlorophyll)

Sea Ice Analysis for a Potential Mackenzie Delta Ship Terminal

ASL’s remote sensing team aided in a pre-feasibility study for the Government of the Northwest Territories to support a potential natural gas export project situated in the Mackenzie Delta. To evaluate the viability of year-round shipping, the team provided the following key analyses:

  • Historical Sea Ice Trends: Leveraged weekly digital ice chart data from the Canadian Ice Service (CIS) archives (1991-2020) to map the percent change in average sea ice concentration over the past three decades.
  • Ice Development Mapping: Mapped decadal changes in mean monthly sea ice state development to identify concentrations of medium-to-thick first-year ice and old ice.
  • Future Route Projections: Evaluated a proposed shipping corridor to the Bering Sea by forecasting seasonal sea ice conditions and shipping impacts for the periods of 2030–2045 and 2046–2060.
Monitoring Salmon Freshwater Habitat in Near-Real-Time using Satellites

ASL has signed a contribution agreement with the Canadian Space Agency for a 2-year project under the Satellite Mobilization for Biodiversity (SaMBA) opportunity, part of the smartEarth funding initiative.

ASL is in works to develop the DeCAF Rapid Response Tool (RRT) to support near-real-time monitoring of salmon habitats. It builds on ASL’s wide-area-monitoring solution DeCAF, and uses advanced deep learning techniques to process open-access or commercial satellite data and find immediate landscape changes, including human disturbances and natural phenomena (i.e. landslide detections are shown in adjacent figure).

ASL is developing this in collaboration with a variety of stakeholders:

  • Kitasoo Xai’xias First Nation
  • DFO Integrated Planning for Salmon Ecosystems (IPSE)
  • Pacific Salmon Foundation (PSF)
  • British Columbia Ministry of Water, Land and Resource Stewardship (WLRS)

Hyperspectral Mineral Mapping in Southwest Greenland

In 2021, ASL completed a project for the Greenland Ministry of Mineral Resources (MMR) to process and analyze a large amount of airborne hyperspectral data over Gardar Province in south Greenland. The airborne data was collected over the Ilímaussaq intrusion and Igaliku Igneous Complex. The survey area is known to be rich in rare earths, but also contains underexplored segments of interest to mineral prospectors.
ASL generated mineral maps for high priority areas which in turn are to be used to support revision of geological knowledge and geoscience information for the mineral exploration industry.
Project services included:

  • Radiometric calibration of survey lines to surface reflectance using field spectra
  • Quality assessment of dataset (artifacts, atmospheric effects, geometric accuracy
  • Hyperspectral mineral mapping of high priority areas of the Gardar Province, identified by MMR as being rich in rare earth elements.
The needle in the haystack: Space-Based Intelligence, Surveillance and Reconnaissance (SB-ISR) imagery for decision making

ASL contributed to the Canadian Department of National Defence (DND) IDEaS program to address challenges in space-based intelligence, surveillance, and reconnaissance (SB-ISR), focusing on detecting concealed human activity in remote regions.

The project developed methods to identify subtle landscape changes—such as soil disturbances and infrastructure development—using satellite imagery. Emphasis was placed on wide-area monitoring beyond routinely observed locations, enabling the detection of emerging activity in sparsely monitored environments.

Using automated time-series analysis and change detection, ASL built workflows to process large satellite datasets, flag anomalies, and support targeted follow-up with higher-resolution sensors.

Project outputs included:

  • Large-area satellite-based change detection workflows
  • Detection of subtle anthropogenic disturbances
  • Automated alerting and sensor cueing concepts
  • Evaluation of methods to reduce false positives
