It's finished but it might be interesting to look at for a number of reasons not least is we managed to complete a project.
We had 3 or 4 new mappers who mapped a dozen or so tiles each. One of these contacted MSF and asked what could they do to help besides financially and MSF directed them to HOT and this project. So we now have NGOs providing mappers. I feel quite pleased that we managed to get a lot of mapping out of new mappers. The instructions were simple, settlements, connecting roads to be labelled unclassified, plus rivers. We had at least two maperthons so the simple clear instructions helped there. The imagery was good. The size of the project was reasonable. Even so it took us nearly a month of mapping. After some initial feedback the quality of mapping improved so less work for validation towards the end. One difficulty was finding new mappers who hadn't marked a tile done but giving feedback to them on their mapping. I validated most tiles, two tiles were invalidated by mappers with about two tiles experience. I only invalidated one tile and that was after adding a fairly large number of settlements to a previous tile by the same mapper when I came across a very large settlement that had been missed in the first few seconds. The rest I just added what was missing and gave feedback. Some more experienced mappers actually mapped more than the instructions requested which is never bad. The project was listed as high priority did that concentrate the mappers efforts? In other words what can we learn from this project and apply it to other projects? Thanks John
