Specialty: Geographic Information Specialist
My work is directed toward geomatics and the application of related technologies in soils, agriculture, and the environment. I largely support faculty, staff, and students in the use of geospatial information and analytics.
Current program emphasis is directed toward (i) the use and application of unmanned aircraft systems (UAS) in early-season nitrogen management and crop scouting, (ii) the optimization of commercial nitrogen inputs through on-farm, multiple rate strip trials, and (iii) the spatial characterization of heavy metals on agriculture land resulting from the 2014 Dan River coal ash spill.
Other technology and programming interests include: web-based distribution of spatial data (RESTful APIs, leaflet, GeoServer, PostgreSQL PostGIS), open-source spatial solutions (GDAL/OGR), mobile application development, spatial analytics (R), and the development of tools and services for use in agriculture and farm management
