This is a legacy product that is no longer supported. It may not meet current government standards. The Canadian Digital Surface Model (CDSM) is part of Natural Resources Canada's altimetry system designed to better meet the users' needs for elevation data and products. The CDSM product consists of a derived product from the original 1 arcsecond Shuttle Radar Topographic Mission (SRTM) Digital Surface Model (DSM). **This third party metadata element follows the Spatio Temporal Asset Catalog (STAC) specification.**

This dataset contains new detailed surface water maps of Canada showing where and how often surface water has occurred at each location across Canada, and how it has changed from 1984-2023. Freely-available archived imagery from the Landsat series of satellites was used to map water at bi-weekly and annual time periods, and these time-series were used to create dynamic surface water maps at 30m spatial resolution across Canada. **This third party metadata element follows the Spatio Temporal Asset Catalog (STAC) specification.**
