TanGeoMS: Tangible Geospatial Modeling System

Abstract

We present TanGeoMS, a tangible geospatial modeling visualization system that couples a laser scanner, projector, and a flexible physical three-dimensional model with a standard geospatial information system (GIS) to create a tangible user interface for terrain data. TanGeoMS projects an image of real-world data onto a physical terrain model. Users can alter the topography of the model by modifying the clay surface or placing additional objects on the surface. The modified model is captured by an overhead laser scanner then imported into a GIS for analysis and simulation of real-world processes. The results are projected back onto the surface of the model providing feedback on the impact of the modifications on terrain parameters and simulated processes. Interaction with a physical model is highly intuitive, allowing users to base initial design decisions on geospatial data, test the impact of these decisions in GIS simulations, and use the feedback to improve their design. We demonstrate the system on three applications: investigating runoff management within a watershed, assessing the impact of storm surge on barrier islands, and exploring landscape rehabilitation in military training areas.

The aptness of Tangible User Interfaces for explaining abstract computer network principles

“…Within the architectural domain, a successful TUI system, URP, was employed to model the illumination, wind and shadow casting effects of multiple buildings during different daylight stages [45] [46]. The ability to visually model systems proved also useful in geospatial modelling whereby the TUI system developed by [47] allowed for investigating terrain sculpting options and subsequent designs for stormwater runoff management. The modelling of physical situations whilst interacting dynamically with affecting parameters was adopted in the Strip'TIC system which allowed air traffic controllers to visualize, understand and control events within an airspace.…”

Tangible Landscape: Cognitively Grasping the Flow of Water

“…The aim of coupling Illuminating Clay with GRASS GIS was to 'explore relationships that occur between different terrains, the physical parameters of terrains, and the landscape processes that occur in these terrains' (Mitasova et al, 2006). The effort to couple a physical landscape model with GRASS GIS led to the development of the Tangible Geospatial Modeling System (Tateosian et al, 2010) and Tangible Landscape ( Fig. 1) (Petrasova et al, 2014, Petrasova et al, 2015.…”

ReservoirBench: An Interactive Educational Reservoir Engineering Workbench

“…Within the realm of geology and reservoir engineering, TUI's [7,10,15], tabletop interfaces [19,20] and a web-based interface [4] have been previously introduced. However, the focus in these instances of research has mainly been on data exploration.…”
