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.

Landscape unit based digital elevation model development for the freshwater wetlands within the Arthur C. Marshall Loxahatchee National Wildlife Refuge, Southeastern Florida
The hydrologic regime is a critical limiting factor in the delicate ecosystem of the greater Everglades freshwater wetlands in south Florida that has been severely altered by management activities in the past several decades. "Getting the water right" is regarded as the key to successful restoration of this unique wetland ecosystem. An essential component to represent and model its hydrologic regiAuthorsZhixiao Xie, Zhongwei Liu, John Jones, Aaron L. Higer, Pamela A.

This report describes a science strategy for the geologic activities of the U.S. Geological Survey (USGS) for the years 2010-2020. It presents six goals with accompanying strategic actions and products that implement the science directions of USGS Circular 1309, 'Facing Tomorrow's Challenges-U.S. Geological Survey Science in the Decade 2007-2017.'

The potential effects of long-term urbanization and climate change on the freshwater resources of the Flint River basin were examined by using the Precipitation-Runoff Modeling System (PRMS). PRMS is a deterministic, distributed-parameter watershed model developed to evaluate the effects of various combinations of precipitation, temperature, and land cover on streamflow and multiple intermediate hAuthorsRoland J.

Ground-based studies of biogeochemistry and vegetation patterning yield process understanding, but the amount of information gained by ground-based studies can be greatly enhanced by efficient, synoptic, and temporally resolute monitoring afforded by remote sensing. The variety of presently available Everglades vegetation maps reflects both the wide range of application requirements and the need tAuthorsJohn JonesEffects of including surface depressions in the application of the Precipitation-Runoff Modeling System in the Upper Flint River Basin, Georgia
This report documents an extension of the Precipitation Runoff Modeling System that accounts for the effect of a large number of water-holding depressions in the land surface on the hydrologic response of a basin. Several techniques for developing the inputs needed by this extension also are presented. These techniques include the delineation of the surface depressions, the generation of volume esAuthorsRoland J. Viger, Lauren E. Hay, John Jones, Gary R.

The weather data described in this document are being collected as part of a U.S. Geological Survey (USGS) study of changes in Shenandoah National Park (SNP) landscape phenology (Jones and Osbourne, 2008). Phenology is the study of the timing of biological events, such as annual plant flowering and seasonal bird migration. These events are partially driven by changes in temperature and precipitatiAuthorsJohn Jones, Danielle P. Aiello, Jesse D. OsborneDetecting Evidence of Climate Change in the Forests of the Eastern United States
Changes in land use or disturbances such as defoliation by insects, disease, or fire all affect the composition and amount of tree canopy in a forest. These changes are easy to detect. Noticing and understanding the complex ways that global or regional-scale climate change combines with these disturbances to affect forest growth patterns and succession is difficult. This is particularly true for rAuthorsJohn Jones, Jesse D. OsborneAdvanced Remote Sensing Research
'Remote sensing' is a generic term for monitoring techniques that collect information without being in physical contact with the object of study. Overhead imagery from aircraft and satellite sensors provides the most common form of remotely sensed data and records the interaction of electromagnetic energy (usually visible light) with matter, such as the Earth's surface. Remotely sensed data areAuthorsTerrence Slonecker, John Jones, Susan D. Price, Dianna HoganConceptual Design of the Everglades Depth Estimation Network (EDEN) Grid
