At my institute we are revising and updating a methodology for participatory mapping of land degradation, that involves creating a simple land use map, subdividing each land use unit in a number of sub-categories (e.g north vs. south exposed areas) and assigning quantitative and qualitative values to a certain number of pre-defined attributes (e.g cause of degradation, degradation level, counter measures implemented, ...). We are exploring the idea of providing users with a custom made version of QGIS with a very simplified interface, and custom buttons to guide the users to the different steps of the evaluation. Is this technically possible and allowed by the license terms?
