Participants got access to the Qgis project. At the moment our cloud is a bit overwhelmed… so as soon as it gets (hopefully) usable again, I will post here the introductory presentation and the link to the data package (some 4 GB). No rocket science, just a little Qgis project, supposed to work with Mappy and Qgis porting of FGDC planetary symbols.
