Sharing the Perception of Credibility in Participatory Investigation (2019) – draft

Noisy-Champs (Paris, France) Feb. 2, 2019, 3.30PM

Presentation of the discussion by (in alphabetical order) Giacomelli A., Goebel C, Vargiu A., Van Reeth N, Zimmerman N, concerning the issue of credibility in the context of participatory investigation. Closing session of the workshop “Empowering civil society through participatory investigation?” promoted by the European Citizen Science Association in collaboration with various subjects.

In this summary I applied for the first time in public an idea which I had in 2014 or 2015 in Scansano (Southern Tuscany) during breakfast at Bar delle Cascine (the notes of this are in Tatti, Southern Tuscany).

I proposed to my colleagues the idea of putting this draft into a better shape, since all the workshop participants found it very interesting for its contents and the way they were presented…this is a work in progress in February. If you are interested to know more, please write to

“white night” in Massa Marittima

“White nights” are initiatives in Italy where a city hosts events all night long (or as far as possible into the night).

In this case I proposed the presence of a small stand combining the promotion of the Italian OSGEO Chapter, the M(‘)appare Milano project, The Revenge of the Killer Chihuahua and of the Zombies, BuioMetria Partecipativa, palla a 21 etc. (at the end of the day, a typical set).

A POV of this event is visible in the initial part of this video.

GRASS: A Historical Perspective and Some Working Assumptions for its Development

This talk was presented at the Eighth Italian GRASS users meeting, held in Palermo, Sicily, on Feb 14-16, 2007. The talk was #2 in the meeting schedule. This was not the first time I was speaking about free/open-source software, but it was the first time I was speaking about free/open-source geographic software. During the same days we also had the founding meeting for, the Italian OSGEO chapter, where I ended up acting as the facilitator of the two-day discussions.


The presentation will provide some historical references to the development and the distribution of this system, in order to derive indications for its future developments. The presentation will consider various experiences made by the author, using GRASS since 1993, for applications in different settings (universities, public, and private sector), in relation to different domains (hydrology, remote sensing, archaeology), and for projects with different objectives (research, production, training). These cases will be presented with reference to two types of “environment”, i.e. GFOSS-only environments, and “hybrid” environments, where GFOSS and proprietary tools coexist. Experiences from subjects who have been directly involved in the development of GRASS from the mid-Eighties to the mid-Nineties will be discussed, focusing on the phase where GRASS phased from USACERL to other maintainers, eventually leading to the current situation. The aim of the presentation is to contribute to the identification of possible strategies for the upcoming developments of the GRASS project, in consideration of some critical points which emerged in the past.
