The Free and Open Source paradigm is no longer a novelty in the geospatial world. There are numerous, stable and powerful solutions, services, libraries built and maintained in the spirit of FOSS. The movement has long overcome the status of a garage hobby, infiltrating all sectors. There are hundreds of relevant events around the world each year, from conferences to hackathons, workshops and seminars, studies and reports analysing open source business models, funding schemas and explicit requests for projects that built software to make it open source. In this agile context, it is difficult, if not impossible to keep up to the speedy developments, to make use of what is already out there and investing resources in improving and not building from scratch.
This talk presents the ongoing endeavour to create a dynamic and interactive visualization of the free and open source software for the geospatial ecosystem. Using a directed graph build with D3.js, the authors attempted to sketch the connections between existing solutions. The 400+ identified solutions have been divided into 5 categories: core-libraries, server-side, desktop, web tools and mobile, and linked to the specific type of Open Source license and programming languages. Although still in an incipient shape, the graph offers an intriguing glimpse of this intricate ecosystem.
This research started in the context of an exercise of the European Association of the Remote Sensing Companies and has been continued by the authors. The higher scope is to find the best way to open this tool for the community so that developments that spring all over the world can be illustrated in a near-real time framework.

Codrina Ilie is a technical geographer, an open source GIS power user, actively working in improving open data services development at Terrasigna. In the last 4 years, her work has been divided between open data initiative development and geodata standardization and interoperability. In her 8 years of activity, Codrina has essentially focused on using open source GIS solutions for data management, processing and visualization. As an advocate for foss4g, since 2010 she has been a volunteer trainer in the Romanian geospatial community, geo-spatial.org. Since 2013, Codrina has been a Charter Member of the OSGeo.
