Research interests
In more than 25 years of research, most of Steve's emphasis has centered on the use of time-series remotely sensed imagery for land cover mapping and monitoring applications. Although some of his work has used (and continues to use) multiseasonal imagery from Landsat and similar sensors, he currently is more focused on the use of dense time-series imagery from wide-field sensors such as MODIS. Recent and current studies include using time-series imagery to map the agricultural landscape of the Central Great Plains; examining the relationship of vegetation phenology metrics (VPMs), such as onset of greenness, to actual vegetation growth stages and conditions on the ground; and exploring the impacts of date variations in maximum-value NDVI composites.

In addition to the study and application of time-series remotely sensed imagery, he also is involved in the use of geospatial technologies for responding to, and mitigating, both natural and human disasters. In that regard, he has been involved for several years with a team from KU in assisting the Geneva International Centre for Humanitarian Demining in evaluating a handheld mapping system for creating field databases of minefields. The group also has ongoing research projects to create inundation databases for the state of Kansas to assist in mapping predicted flood extents.


Current projects

  • Use of time-series satellite imagery to characterize and monitor land use and land cover.
  • Evaluation of geospatial technologies for mapping and maintaining minefield databases.
  • Geographic aspects of genocide, ethnic cleansing, and related crimes against humanity.
