Begin with the map's purpose
Natural Resources Canada's landslide research overview links geological context and mapping resources. Different resources can describe past events, terrain susceptibility or particular research areas. Read the study name and geographic extent before treating a national directory as a uniform map of all Canadian communities. A link to research is not an active warning for the place named in that research.
The Government of Canada open-data catalogue helps locate datasets and their publishers. Inspect the metadata attached to each result: study date, coverage, format and limitations. A newly updated catalogue entry can still describe an older survey. Its metadata publication time is not necessarily the time a landslide occurred.
Distinguish records from susceptibility
The USGS explanation of landslide hazard maps supplies general scientific context for the distinction, not Canadian local instructions. An inventory marks known or mapped events; a susceptibility product describes terrain characteristics associated with possible failure. Do not interpret a missing inventory point as the lowest susceptibility class, or a high-susceptibility area as a confirmed current event.
When investigating a British Columbia valley or a Canadian highway corridor, first check whether the selected dataset actually covers that place. Then identify the map's scale and geometry. A regional footprint, a generalized point and a modelled cell have different precision. Zooming a basemap to a building cannot turn a broad regional study into a property-specific assessment.
Keep current notices outside the historical inventory
EmergencyInfoBC provides verified emergency information for British Columbia and links to responsible local notices. It is a provincial source, not a nationwide Canadian landslide-alert database. For other provinces or territories, identify the responsible regional authority. A historical research map should not be used to cancel a current closure or emergency notice.
PocketWorld has no landslide layer or landslide markers and does not assess slope stability. The explorer link opens other disaster layers for related geographic context, not Canadian landslide coverage. Use the official Canadian research and catalogue links above for those datasets. Our methodology explains the coverage of supported providers; it does not imply a landslide feed or a complete road-closure service.
For a careful comparison, retain the publisher, study period, extent, resolution and dataset purpose. Link the current local notice separately from the research layer. This makes a useful regional explanation without suggesting that all blank areas were surveyed, that an old mapped slide has become active again or that a terrain colour predicts exactly when a particular slope will fail.
