ISOGA: A system for geographical reachability analysis


Innerebner, Markus; Böhlen, Michael Hanspeter; Gamper, Johann (2013). ISOGA: A system for geographical reachability analysis. In: W2GIS, Banff, AB, Canada, 4 April 2013 - 5 April 2013, 180-189.

Abstract

In this paper, we present a web-based system, termed ISOGA, that uses isochrones to perform geographical reachability analysis. An isochrone in a spatial network covers all space points from where a query point is reachable within given time constraints. The core of the system builds an efficient algorithm for the computation of isochrones in multimodal spatial networks. By joining isochrones with other databases, various kinds of geospatial reachability analysis can be performed, such as how well is a city covered by public services or where to look for an apartment at moderate prices that is close to the working place. ISOGA adopts a service-oriented three-tier architecture and uses technologies that are compliant with OGC standards. We describe several application scenarios in urban and extra-urban areas, which show the applicability of the tool.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
