Creating a Detailed Wetland Inventory with Sentinel-2 Time-Series Data and Google Earth Engine in the Prairie Pothole Region of Canada

Prairie pothole wetlands are both seasonally and annually dynamic, can be very small, and are frequently impacted by human activity. Their conservation and management relies on accurate inventories. This publication combines flooding frequency (i.e., hydroperiod) mapping using Sentinel-2 satellite images from multiple seasons and years, and satellite-derived vegetation height information to generate a wetland inventory of southern Alberta's prairie pothole region. The methods require minimal training data and proved effective for capturing seasonal wetland features.
