Through my research, I pursue two over-riding goals: (1) increased understanding of relationships among land surface dynamics, hydrologic, and biologic processes; and (2) the provision of resource management relevant information to decision-makers. To meet these goals, research is focused on developing new methods to measure and monitor biophysical characteristics of various land covers.
John has been developing and applying geospatial technologies to improve process understanding and resource management for nearly four decades. His current emphasis is on the development and application of methods and products to monitor inland surface water dynamics from local through global scales. He is particularly interested in the fusion of data collected by various sensors to provide the highest quality time-series data possible. Collaboration across disciplines and institutions improves the quality of his work. Before joining the USGS, John worked as a geospatial technology applications specialist in state government and private industry. Since joining the USGS, John has engaged in research, strategic planning, training, mentoring, and outreach. Specific research endeavors have included: snow cover mapping; incorporating remote sensing and landscape ecology in Everglades restoration science; wetland bathymetry modeling; evaluating the role of vegetation in hydrology (e.g., spatial and temporal variations in evapotranspiration; precipitation interception and resistance to surface water flow); land surface phenology; impervious surface data accuracy assessment; mapping irrigated lands and estimating agricultural water use; land surface inundation/depth dynamics - especially in wetlands; remote sensing of river discharge; and hazard mitigation.
