Preface
This book introduces Tangible Landscape, an open source tangible user interface for geospatial modeling and visualization powered by GRASS GIS and Blender. With Tangible Landscape a physical and a digital model of a landscape are coupled through a near real-time cycle of 3D scanning, geospatial modeling, and projection. This gives geospatial data an interactive, physical form with which users can intuitively interact. Users can, for example, sculpt new landforms with their bare hands to change the flow of simulated digital water, creating new streams and lakes. They can plant forests by simply placing pieces of colored felt that are immediately rendered as 3D trees. This makes geographic information
