Medium Resolution Digital Elevation Model From Natural Resources Canada’s CanElevation Series (MRDEM-30)

Elevation data are a core theme provided by the Natural Resources Canada (NRCan) to Canadians as essential geographic information. Elevation data are a fundamental input for many types of studies and applications and also serve as a basemap for …

From Data to Action: FHIMP and the Future of Flood Risk Governance in Canada

At GeoIgnite 2025, Maxim Fortin, Senior Engineer Advisor at Natural Resources Canada (NRCan), delivered a standout session on Canada’s evolving approach to flood hazard mapping. Representing the team behind the Flood Hazard Identification and Mapping …

2024 Research: Year in Review

Overview of peer-reviewed publications related to flood modelling and climate change in 2024

Large-scale flood modelling based on LiDAR data: a case study in the Southwest Miramichi watershed, New Brunswick, Canada

With Canada’s river basins extending over almost 10 million km2, producing flood maps sufficiently accurate to be used for planning purposes at a reasonable cost is a challenge. Bathymetric data, in particular, are difficult and expensive to obtain …

Post-wildfire boreal forest vegetation cover change mapping via information fusion for secondary disaster risk assessments

Post-wildfire vegetation cover damage and loss can escalate the risks of secondary disasters such as flood, landslide, and water contamination, particularly in a major wildfire affected region where human settlements are situated. In assessments of …

Pluvial flood modeling for coastal areas under future climate change – A case study for Prince Edward Island, Canada

It has been increasingly understood that pluvial flooding poses a substantial risk to numerous communities across the globe. This is especially relevant for the Canadian province of Prince Edward Island (PEI), which is susceptible to a compound flood …

Global Flood Partnership: Flood Hazards in Canada: Update from the National Flood Mapping Program

Since 2021, the Government of Canada has invested $63.8M in the Flood Hazard Identification and Mapping Program (FHIMP) to help Canadians better plan and prepare for future flood risks. In this presentation, Natural Resources Canada (NRCan) will …

Open Building Population Layer (Canada) - 2021

Open Building Population Layer for Canada, derived from open-source computer-generated footprints and census data (2021)

A rapid high-resolution multi-sensory urban flood mapping framework via DEM upscaling

Urban floods can cause severe loss of economic and social assets, and remote sensing has been an effective tool for flood mapping during disaster response. Due to the complexity of high-density urban structures, high-resolution (HR) optical images …

A GIS-based method for identifying gaps in building footprint coverage

This article presents a method for identifying areas where there are gaps in large-scale building footprint layers, using building population and census datasets
