The simple answer to the question of what information to collect is probably quite obvious from your goal, but when you dig down the answer isn't always that easy. So if you need a territory map for a land claim then you probably need to collect information about territory use, as well as the territory boundaries or limits - but exactly what information do you need, what format should it be in, how much detail do you need, etc. And if you want to collect evidence of illegal gold mining, then you may want to collect georeferenced photos and answer a series of questions about the scale and nature of any impacts found, but what is the best way of framing questions to get you the answers your community and perhaps legal team need to evaluate what is going on and how to take action, and what should you be taking photos of exactly?
