* Description: Tangible Landscape is a tangible interface for geographic information systems (GIS). It interactively couples physical and digital models of a landscape so that users can intuitively explore, model, and analyze geospatial data in a collaborative environment. Conceptually Tangible Landscape lets users hold a GIS in their hands so that they can feel the shape of the topography, naturally sculpt new landforms, and interact with simulations like water flow. Since it only affords a bird's-eye view of the landscape, we coupled it with an immersive virtual environment so that users can virtually walk around the modeled landscape and visualize it at a human-scale. Now as users shape topography, draw trees, define viewpoints, or route a walkthrough, they can see the results on the projection-augmented model, rendered on a display, or rendered on a head-mounted display. In this paper we present the Tangible Landscape Immersive Extension, describe its physical setup and software architecture, and demonstrate its features with a case study. | * Description: Tangible Landscape is a tangible interface for geographic information systems (GIS).

* Description: Increasing global population is accelerating urbanization and rapidly transforming natural systems to impervious built environments. Emerging development challenges include: where (and how) can people live without compromising the natural resources and land systems needed for sufficient food, water, and energy production, and how do we minimize the ecological footprint of cities for maintaining wildlife habitat and special places for outdoor recreation? Despite the important role urbanization plays in the well-being of urban residents, few tools are available for examining the long-term impacts of urban growth. The FUTURES (FUTure Urban-Regional Environment Simulation) model is a new user-friendly, open-source geospatial computer model for simulating urbanization and landscape fragmentation. FUTURES simulates landscape change based on demand for development, local site suitability factors, and a stochastic patch-growing algorithm. In this presentation, I will demonstrate the FUTURES model giving practical advice on how it is implemented, and instructions on how users can leverage the open-source application for their own urban simulation projects. We will explore results for North Carolina to understand how the model can help better understand pressures related to urban growth. Results highlight the tradeoffs of different growth strategies for both local economies and ecological system important for urban residents. FUTURES is an important springboard for initiating and guiding dialogue about planning priorities by helping stakeholders untangle complex urban-related challenges related to rapid urban growth. | * Description: Increasing global population is accelerating urbanization and rapidly transforming natural systems to impervious built environments.

* Description: US Army CERL started GRASS GIS development in early 80s. Since then, researches around the world have been selecting GRASS GIS as a platform for their new tools. Early on GRASS GIS got 3D view, advanced interpolation methods, hydrology and image processing tools. 3D rasters and time series are now standard data types at the same level as vectors or rasters. Recent developments include novel landform detection, tangible user interface and spatio-temporal algebra. This talk will cover all of this and will show why you should start using GRASS GIS today. | * Description: US Army CERL started GRASS GIS development in early 80s.

* Description: With the increased availability of UAS technologies we can produce extremely high resolution 3D data as often as we need for monitoring of crops, landscape processes, or natural hazards. For certain applications the limited extent of UAS-based data requires us to merge the high resolution topography with other data sources such as lidar. However, simple patching creates discontinuities or artificial edges in the merged DEMs leading to artifacts in modeling results and visualization. In this presentation I will show how to derive seamless digital elevation models combining different sources including time-series of UAS, lidar, and Kinect data, and I will explain how this simple, yet powerful method can be implemented in GIS. | * Description: With the increased availability of UAS technologies we can produce extremely high resolution 3D data as often as we need for monitoring of crops, landscape processes, or natural hazards.

- Description: Tangible Landscape is a tangible interface for geographic information systems (GIS). It interactively couples physical and digital models of a landscape so that users can intuitively explore, model, and analyze geospatial data in a collaborative environment. Conceptually Tangible Landscape lets users hold a GIS in their hands so that they can feel the shape of the topography, naturally sculpt new landforms, and interact with simulations like water flow. Since it only affords a bird's-eye view of the landscape, we coupled it with an immersive virtual environment so that users can virtually walk around the modeled landscape and visualize it at a human-scale. Now as users shape topography, draw trees, define viewpoints, or route a walkthrough, they can see the results on the projection-augmented model, rendered on a display, or rendered on a head-mounted display. In this paper we present the Tangible Landscape Immersive Extension, describe its physical setup and software architecture, and demonstrate its features with a case study.

How innovations thrive in GRASS GIS
by Vaclav Petras (presenter, typesetter), Yann Chemin, Martin Landa, Thomas Leppelt, Pietro Zambelli, Luca Delucchi, Margherita Di Leo, Sören Gebbert, and Markus Neteler
- Citation: Vaclav Petras, Yann Chemin, Martin Landa, Thomas Leppelt, Pietro Zambelli, Luca Delucchi, Margherita Di Leo, Sören Gebbert, and Markus Neteler (2017). How innovations thrive in GRASS GIS. Poster at NCGIS2017 Raleigh, NC, USA, Feb. 22-24, 2017
- Highlights: Algorithms and models included in GRASS GIS remain available long term. Analytical tools are not limited to one domain but spread across many fields. New tools can be built based on functionality or code of the existing ones regardless of the particular domain of problems they belong to. Both the functionality and the code are evaluated by the community of users and developers in different fields and scales.
- Outline: Lidar Data Processing, Water, Floods and Erosion, Image Segmentations, Topology, Cleaning, Overlays, Attributes, Spatio-Temporal Data Analysis, Vector Network Analysis, Landscape Structure
