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.

gFlowiz follows the new paradigm of « visualization mapping » (MacEachren, 2004) not present in current geoweb applications.
All types of flows, movements and traffic in a geographical space, at several scales, are involved (migrations, freight, transportation, etc).
Required semiological, aesthetical and design elements offered by currently web-based graphic visualization libraries are also considered.
Its main goal is to build a simple application combining two pillars of scientific graphical representation: flow data processing and (geo)graphical modalities visualization.
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.

This presentation will follow 3 axes: open source applications in the curated corpus, an analysis of the survey and a current development status of the application

In the early ages of Computer Science, there was only Command Line Interface (CLI).
No mouse, no windows. But computers was already able to do more than just calculus.

First of this kind -- in the early eighties ! -- GRASS GIS was able to manipulate,
analyze and visualize geospatial data. All in CLI. But it was frightening for
most users. CLI is terrifying.

Then graphical interfaces arrived with windows and mouses. Computers started to
be cheaper and more affordable. Almost everyone now can own and use a computer.
With a graphical interface.

Less scary, more accessible. And GIS followed the trend. ESRI created ArcMap,
QGIS was born. Even GRASS GIS got a Graphical User Interface at some point.

But isn't CLI making a come back ? Quietly ? Even in our small geospatial heaven ?
Let's have a look at behind the curtain and see what CLI can offer nowadays with
the Python and R datascience stacks.

Let's look at CLI GIS, right in the eye !

By the end of the talk audience members will : * not be afraid of CLI anymore (let's hope) * might want to learn a scripting language and explore console mode * want to combine best of both worlds

OSGeoLive is a self-contained bootable DVD, USB thumb drive or Virtual Machine based on Lubuntu, that allows you to try a wide variety of open source geospatial software without installing anything. It is composed entirely of free software, allowing it to be freely distributed, duplicated and passed around.
It provides pre-configured applications for a range of geospatial use cases, including storage, publishing, viewing, analysis and manipulation of data. It also contains sample datasets and documentation.
OSGeoLive is an OSGeo project used in several workshops at FOSS4Gs around the world.

OSGeoLive 13.0 will be released at the end of July 2019 ready for FOSS4G 2019.
Still working on the improvements initiated for OSGeoLive 12.0, it will embedded latest stable version of a vast choice of Open Source Geospatial software. The work on the geodata science with Python and R stacks have also been continued. Documentation is also a big building area and we made a proposal to Google Season of Docs in order to get it even better. We would like to encourage people around the world to help us translate it.
This presentation will reflect what we did for OSGeoLive 13.0, what choices have been made, what we plan to do for 14.0 and after.
