Abstract

  • In the last few decades, geospatial simulations have become increasingly common in scientific research as a method to study complex spatial phenomena, such as urban growth or disease spread, and to effectively prevent or mitigate natural hazards, including flooding or wildfires. Although exploring simulated scenarios can help us predict future demands and risks associated with decisions and policies, geospatial simulations are often not designed for practical use in management. The black box nature and the lack of user-friendly interfaces of simulation tools make them inaccessible for decision makers and stakeholders, leading to a knowledge-practice gap. To address this challenge, we developed a decision support system on top of Tangible Landscape, an open source tangible geospatial modeling platform. By coupling a physical, scaled model of a landscape with powerful geospatial modeling platform, Tangible Landscape allows decision-makers to intuitively modify landscape and perform spatial interventions while instantly visualizing and quantifying the resulting effects. Tangible, spatio-temporal steering of the simulation enhances understanding of simulated processes, communicates uncertainties and builds trust between decision-makers and researchers. As a case study, we are leveraging this novel modeling platform to engage stakeholders involved in the management of a weather-driven plant disease aggressively spreading in California and Oregon. Our results suggest that Tangible Landscape is a promising platform for supporting decisions and building more robust, accurate scientific models.

NCSU Booth

NCSU CGA booth with a Tangible Landscape demo
  • NCSU Center for Geospatial Analytics was promoting NCSU, the center, and its educational programs, especially new PhD program in Geospatial Analytics.
  • A live iterative Tangible Landscape demo was part of the booth.
  • Besides NCSU CGA flyers and stickers, Tangible Landscape and GRASS GIS flyers and stickers were provided because of involvement of NCSU CGA in these projects.
  • Tangible Landscape demos: surface water flow and ponding, planting trees, drainage and contributing area, routing and blocked streets, coastal flooding, HAND
  • NCSU CGA students, postdocs, and faculty were present at the booth.
