Arabesque: a geographic flow visualization application
Abstract
Arabesque is a FLOSS web application dedicated to flow mapping and analysis. Using web technologies, it provides tools to the user to load O/D data. The user can easily modify filters parameters or add new ones. A default symbology is proposed but the user can define is own. Arabesque aims to provides a fast, lightweight framework to visualize and explore flow data with a special attention on graphics and symbology in order to produce beautiful and just flow maps. This presentation will be a short presentation of the project and a quick demo of the application. It is the extension of the presentation made at FOSS4G 2019: release, code publication, updates and a live demo. Geographic flow visualization (gFlowiz) is an interdisciplinary project dedicated to flows and networks in the geoweb. It is led by a team of French researchers and engineers in Geography, Cartography and Computer Science from both IFSTTAR and CNRS. A state of the art on current issues of flows and movement analysis on the geoweb has been produced through the compilation of around 70 applications in a thematic dashboard, and a 200 respondants survey on flow map usages and needs has been realized. The results of this were combined to create the specifications of the Arabesque application. Arabesque is a FLOSS web application dedicated to flow mapping and analysis. Using web technologies, it provides tools to the user to load Origin/Destination data in robust and well documented formats (CSV or geojson). Arabesque will display the most significant data at launch but the user can easily modify filters parameters or add new ones on nodes and/or links. A default symbology is proposed but color scales, size, transparency and shape of objects can be modified as well. Arabesque aims to provides a fast, lightweight framework to visualize and explore flow data. A special attention has been provided on graphics and use of correct symbology in order to produce beautiful and just flow maps. This presentation will be a short presentation of the Gflowiz project and a quick demo of the Arabesque application.
