Martinique was chosen for this training and because of its remoteness from the European continent, georeferencing will use a satellite signal, whose protocols are different from those used by the other four partners in Europe, thus an important form of evaluation of performance of the tools and application created for this purpose. <br> <br> This training was planned in two parts: <br><br> - A first theoretical part for participants to understand the notions important for georeferencing: description of the global positioning system, explanation of the geodetic reference system, interpretation of GPS principles, precision of positioning modes, presentation of the georeferencing tools needed for Marking of GPS points. <br> <br> - The second part will be essentially practical. Participants will go to the field to conduct experiments and apply the learning from the theoretical part. They will also input the satellite data and record the coordinates, using the tools and application for android system created for this purpose. <br><br> Objective: to acquire the necessary skills and to use, precisely and efficiently, the georeferencing tools on the Smartphones and the tablets, with a view to the creation of the educational paths and the points of interest respectively. Training and trainees will be evaluated and the participants certified. <br><br> Number of participants: 25
