Topological and Geometric Data Handling for Time-Dependent Geo-Objects Realized in DB4GeO,ging their locations and shapes in time is a central task. For example, the documentation of landfills, mass movements or volcanic activities requires 4D modeling based on dynamic geometric and topological database structures. In this contribution we present our concepts and implementation efforts f

Segmenting Trajectories by Movement States,evelopment. In this study, we revisit and extend a framework for trajectory segmentation based on spatio-temporal criteria for this purpose. We adapt and extend the framework to the setting of segmentation according to the individual movement states of an object, in particular an animal. We implemen

Evaluating the Cognitive Adequacy of the DLine-Region Calculus,nts or geographic entities. They are ubiquitous in ontological modeling, information retrieval, they play a central part at the human-machine interface, and are critical to process data collected from geosensor networks. What is common to all these application areas is the search for a mechanism to

Integrating Change Vector Analysis, Post-Classification Comparison, and Object-Oriented Image Analyethod combines change vector analysis (CVA) and post-classification analysis (PCC) to detect LULC changes using RADARSAT-2 PolSAR images based on object-oriented image analysis. A hierarchical segmentation was implemented on two RADARSAT-2 PolSAR images acquired at different times to delineate image

Modifying Areal Interpolation Techniques for Analysis of Data on Food Assistance Benefits,a, policy makers, and non-profit groups. Much of this research relies on the proximity of large grocery stores as a measure of food access. These studies have been limited by poor data quality, boundary effects, and scale dependence.
