Envisioning Uncertainty in Geospatial Information
Geospatial reasoning has been an essential aspect of military planning since the invention of cartography. Although maps have always been a focal point for developing situational awareness, the dawning era of network-centric operations brings the promise of unprecedented battlefield advantage due to improved geospatial situational awareness. Geographic information systems (GIS) and GIS-based de...
متن کاملEvaluating Visualizations of Geospatial Uncertainty
Many techniques have been proposed for visualizing uncertainty in geospatial data. However previous empirical research on the effectiveness of visualizations of geospatial uncertainty has focused on user intuitions rather than objective measures of performance when reasoning under uncertainty (MacEachren, et. al, 2012). In two experiments, we examined the effectiveness of four alternative visua...
متن کاملManaging Uncertainty in Geospatial Predictive Models
Geospatial predictive models often require mapping of predefined concepts or categories with various conditioning factors in a given space. This chapter discusses various aspects of uncertainty in predictive modeling by characterizing different typologies of classification uncertainty. It argues that understanding uncertainty semantics is a perquisite for efficient handling and management of pr...
متن کاملAnalyzing and Comprising the Location of SIX Universities in Tehran Using Geospatial Information Systems
Universities as the places of training the experts play an essential role in social, economic and cultural structure of the nations. The quality of education and the educational space are two major effective factors on the quality of training the students. Since the educational places are of the most important land-uses in the cities, the compatibility of them with other surrounded land-uses is...
متن کاملVisualizing Geospatial Information Uncertainty: What We Know and What We Need to Know
Developing reliable methods for representing and managing information uncertainty remains a persistent and relevant challenge to GIScience. Information uncertainty is an intricate idea, and recent examinations of this concept have generated many perspectives on its representation and visualization, with perspectives emerging from a wide range of disciplines and application contexts. In this pap...
