Submission process is managed in the Pentabarf system used by the FOSDEM conference.

Apply for a talk: https://penta.fosdem.org/submission/FOSDEM20

By submitting a proposal you agree to being recorded and to have your talk made available.

When submitting your talk in Pentabarf, make sure to select the ‘**Open Research Technologies Devroom**’ as the ‘Track’. If you already have a Pentabarf account from a previous FOSDEM event, please reuse it. Create an account if, and only if, you don’t have one from a previous year.

If you have any issues with Pentabarf, do not despair: contact us at science-devroom-manager [at] fosdem.org

### Titles

- title: Developping a geographic flow visualization application in an interdisciplinary research environment
- subtitle: Case of the *Arabesque* application

-> proposition alternative de titre : Developping a geoweb application in an interdisciplinary research environment

### Abstract

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.

Having a research idea can be challenging, especially when it is an application and your are not a developer. You need to gather talents you miss by creating a team, review existing apps and see where is the state of the art. Make technology choices, choose development and distribution models. Find publishable datasets. Many things that are not trivial for many reseachers.

This talk is about the *Arabesque* journey, from the idea to the publication of a FOSS application.

### Title
*Arabesque*, a geographic flow visualization application
### Abstract (577 characters)
*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.

### Full description
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.
