WaterMAP (https://apps.usgs.gov/watermap) is an interactive web application that brings together comprehensive views of surface water conditions in rivers, lakes, and reservoirs, everywhere in the US. The application allows users to explore water conditions over time using both satellite observations and onsite measurements. We will demonstrate best practices to leverage and integrate each data catalog while highlighting the interactive mapping and visualization capabilities, as well as data search/filter/download functionalities. Live demos will present use cases to improve workflows for USGS hydrologic technicians and scientists. Data product owners and the development team will be available to answer questions.
