In the instructions of the TM1237, I see Imagery:DO NOT use Drone Imagery. This is out of date and has poor spatial accuracy. What is the purpose of this note? It sound quite negative without any justification. And dont you think this could be perceived as quite negative from our Haiti OSM colleagues that did a great job operating drone over the last few years? I suggest that you correct or remove this instruction.
While in Limonade, Haiti in 2013, I had the opportunity to use drones images of Limonade to trace in detail. I was able to compare both with what I observed walking in the informal and very dense areas of the town and with Satellite Imagery. The drone image was well aligned and provided great details (4cm accuracy). There are no streets in such areas and paths cannot be observed from Satellite imagery (50 cm). Even if the drone image available is older, dont you think that this can complete the information provided from the satellite imagery? And quite easy to align the 2 images. For this area, I see a white surface on the satellite imagery, but the drone imagery let me clearly see the roof.https://www.openstreetmap.org/#map=19/18.562506904365602/-72.30239403945538 Here I can see that cars are parked in the yard.https://www.openstreetmap.org/#map=20/18.562808676685652/-72.30254150088288 Here, it is a lot easier to distinguish the various roofs on the drone imagery.https://www.openstreetmap.org/#map=20/18.56351490050388/-72.30203326964823 Here, I can better distinguish on the drone image each house, plus I can see the path between houseshttps://www.openstreetmap.org/#map=21/18.5649624/-72.3045042 Regard Pierre
