It seems that our mooc facilitators are bringing us down the path of Particpatory 3DGIS. If I had another career it would be in GIS. An incredible tool for inclusion and exclusion, mapping, like any scientific inquiry presupposes the answer and contains the bias of its inquirer. That's what so cool about participatory mapping in 3D. It is the web 2 of mapping. It mixes it up and includes wisdom not found in assumptions but through a deep knowledge of place.
"One of the reasons that tacit knowledge is being surfaced during P3DM is that the relief model helps different elders reflect on their own knowledge and listen to each other. It makes tacit knowledge become coherent and identifiable for the holders of that knowledge. This can be missed using other techniques. It is the link between memory, land and maps which creates a particular focus."
