Petrakis, R.E., Soulard, C.E., Waller, E.K., and Walker, J.J., 2021. National Surface Water Maps using Daily MODIS Satellite Data for the Conterminous United States, 2003–2019: U.S. Geological Survey data release. https://doi.org/10.5066/P9UMFBDE.

Mapping surface water using satellite imagery can be challenging due to obstructions from clouds and cloud shadow. Daily satellite images from the Moderate Resolution Imaging Spectroradiometer (MODIS) can reduce the impact of these obstructions by providing more opportunities to access cloud-free scenes. The PLACE team developed monthly surface water maps for the conterminous United States (U.S.) using the Dynamic Surface Water Extent MODIS (DSWEmod) algorithm for all months from 2003 through 2019. The maps include the following four classes of surface water, based on quantified levels of confidence in the DSWEmod algorithm: i) high-confidence surface water (class 1), ii) moderate-confidence surface water (class 2), iii) potential wetland (class 3), and iv) low-confidence water/wetland (class 4), as well as a not-water class (class 0) and a no-data class (class 9) at 250-meter resolution.
