We used Point Blue Conservation Science's dynamic open-water dataset of water distribution and our telemetry data for duck locations to develop frequently updated habitat maps for the Central Valley and Suisun Marsh in California during October-March of 2014-15 through 2017-18. Telemetry data additionally was used to compare performance of each of three series of habitat maps produced. To create this tabular dataset, we intersected telemetry locations for ducks (vector point data) with habitat maps (raster mosaics) in a Geographic Information System (GIS) and attributed duck locations with map pixel values representing habitat, non-habitat, or unclassified (if data were missing). To develop maps of waterfowl habitat, we used open water data (version without cloud-filling) publicly available on Point Blue Conservation's California Water Tracker web site and which Point Blue Conservation Science derived at 16-18 day intervals from mosaics of Landsat 8 imagery for the region including the Central Valley and Suisun Marsh. Each record in the data set represents a duck location by species (column 1) bound to the spatial extent of the Central Valley and Suisun Marsh for October-March of 2014-15 through 2017-18. Columns 2 - 4 represent attributes assigned to duck locations by each of the three maps that were developed and assessed for accuracy. We used the data set to summarize and compare the proportion of duck locations in habitat for the three maps. We further summarized proportions in habitat by duck species (Mallard versus Northern Pintail) and biological activity (for example, feeding and roosting versus molting).
