We then use leading geovisualization techniques to evolve those computer simulations into interactive tools. The visualizations we develop provide meaningful spatial information in accessible formats that let us easily share scientific data across the university and with myriad government and industry partners. Ultimately, our work provides guidance for solving environmental and societal challenges and advancing the frontiers of geospatial analytics.

Observing Our World
The foundation of spatial data, observations help us understand our changing environment and society. We build from them to design remote sensing technologies and create tools and techniques for analyzing data collected on the ground, in the air via unmanned aerial systems or piloted aircraft, and even from space. We also rely on citizen scientists and public data sources to provide information about the environment and the use of developed spaces.
Remote Sensing and Sensor Networks
Graduate students in the Earth Observation and Remote Sensing Lab collect plant samples and take measurements using field spectrometers in order to design algorithms for interpreting airborne and satellite data.
Forest Ecosystem Stress
Students from historically black colleges and universities develop and use tree probes that monitor forest health across an eastern U.S. forest network for the Remote Assessment of Forest Ecosystem Stress Project.
Physical Activity Patterns
Researchers track the activity patterns of volunteers wearing accelerometers to determine how the spatial configuration of their workplaces and homes influences the amount of exercise in their daily lives.
Data collected by citizen scientists observing leaves in California help researchers track the spread of Sudden Oak Death and develop predictive maps of disease risk to inform management actions.
Modeling Our World
We develop data-driven computer simulations that consider the dynamic interactions between both spatial and temporal dimensions of environmental change and human well-being. Examples include simulations of emerging infectious disease, spread of wildfire, and urbanization. Using these models, we explore scenarios of alternative futures to reveal tradeoffs and uncertainties.
Dynamic Spatio-Temporal Modeling
Our researchers test potential management actions for controlling invasive pests by modeling the movement of termites through an urban area and designing various interventions to curb their geographic spread.
Sudden Oak Death
A spatially explicit model developed by our faculty simulates the spread of Sudden Oak Death in California, accounting for forest composition, local weather conditions and transmission among hosts.
Visualizing Our World
Visualization techniques make the scientific process more transparent by providing easy-to-understand graphical representations and imagery. With geovisualization, we help users with varying levels of expertise explore and interact with complex spatial data. And many of the geovisualization techniques we create advance human-computer interaction by enabling intuitive exploration of data models through tangible gestures and eye movements.
Immersive Virtual Environments
Modified 360-degree photography in a head-mounted display allows our researchers to better understand human perceptions of environments and improve landscape design through virtual reality preference experiments.
Public Space Use
Voxel displays allow geospatial researchers here to visualize in a 3-D space the variable occupancy densities of real places, such as the pedestrian use of a public plaza across different paths and times of day.
Combining geoparsing and eye-tracking technology, GazeGIS displays location-based photos as a reader encounters place names in a passage of text, providing vital geographic context without interrupting a story's flow.
Tangible Landscape and VR
As a user interacts with Tangible Landscape, open source 3-D modeling and rendering software couples with GRASS GIS to create a geo-referenced 3-D model on a screen and in a head-mounted display.
With Tangible Landscape, multiple users drive complex computer models by directly interacting with a physical surface as intuitive hand motions take the place of intensive coding and groups make decisions together.
Tangible Landscape users here are able to sculpt the surface using polymer-enriched sand, define specific points or areas by placing wooden markers or colored sand, and draw paths using a laser pointer.
By developing and providing free and open source software, applications and educational materials, we’re making the practice of open science possible. The decision-support systems we create allow for the visual exploration, analysis and presentation of spatial data required by natural resource and land-use authorities. Finally, scalable computing systems allow us to store, manage and deliver up-to-date, actionable geospatial information to our partners.
Open Science and Open Source
Open Source Community
Our GeoForAll Lab is the primary node for the North American OSGeo Foundation and belongs to the University Consortium for Geographic Information Science, a nonprofit group of invited universities and research institutions.
Helena Mitasova, our associate director for geovisualization, and several of her Ph.D. students serve on the GRASS GIS project steering committee, advancing development of this powerful open source software.
We worked with the Piedmont Triad Regional Council of Governments to develop a decision-support tool for determining if compact and mixed-use developments would yield higher tax values per acre than typical suburban spaces.
National Park Mapping
Our staff and students partner with the National Park Service to create web mapping applications, including ones that allow park visitors to plan out their exploration of trails at Shenandoah National Park.
Our researchers partner with collaborators including the National Park Service to create custom web mapping applications that rely on geospatial databases which are accessible and editable by many users at the same time.
We perform educational research to help everyone from elementary school students to graduate scholars understand and apply geospatial concepts so they can use and eventually create advanced technologies.
Findings and Support
We conduct groundbreaking research on urgent issues ranging from public health to biodiversity. The results and insights gained are consistently featured in peer-reviewed journals.
