OSMatrix – Grid-based Analysis and Visualiza- tion of OpenStreetMap
نویسندگان
چکیده
Since data in OpenStreetMap is mostly surveyed by untrained private citizens rigorous quality control is required in order to produce a reliable data set. “Hidden” information, such as user activities, topicality of data, which is typically not visualized in maps might indicate areas with increased need for quality assessments. OSMatrix is a visual analytics approach that provides such information. The paper presents a short introduction to the OSMatrix application and some preliminary findings drawn from the resulting maps.

Are Crowdsourced Datasets Suitable for Specialized Routing Services? Case Study of OpenStreetMap for Routing of People with Limited Mobility
Nowadays, Volunteered Geographic Information (VGI) has increasingly gained attractiveness to both amateur users and professionals. Using data generated from the crowd has become a hot topic for several application domains including transportation. However, there are concerns regarding the quality of such datasets. As one of the most famous crowdsourced mapping platforms, we analyze the fitness ...
متن کاملUsing Interactive Visualization for Teaching the Theory of Np-completeness
In this paper we investigate the potential of interactive visualiza-tion for teaching the theory of NP-completeness to undergraduate students of computer science. Based on this analysis we developed some interactive Java applets which we use to present an NP-complete tiling problem PUZZLE in our lecture. This software is integrated into our hypertext lecture notes and our students also use it t...

In this paper we present a workload characterization analysis of TIPSY, which is a typical interactive package for scientiic visualiza-tion and analysis. Tools like this are gaining increasing importance as parallel scientiic computations produce increasing amounts of data, raising the need for eecient visualization and data mining. Our experiments show that, although TIPSY has high processing ...

متن کاملAugmented Visualization of Association Rules for Data Mining
This paper describes a proposal for enhanced visualization of a data-‐mining model generated with Association Rule (AR) techniques by applying Self-‐Organizing Maps (SOM). A representation of visual percep-‐ tion model of AR based on a method called AVM-‐DM (Augmented Visualiza-‐ tion Models for Data Mining) is established, together with data and pat-‐ terns, which support the visual expl...
