Imagery interpretation is artful indeed - it takes practice to train the eye, but then recognizing features from elusive hints, such as a tall structure from its shadow, becomes reflex. This is an area where having travelled in the target area helps a lot - with nothing but the imagery I can with near-certainty recognize most Senegalese schools... But I'm entirely lost trying to do the same in neighbouring Guinea ! _______________________________________________ HOT mailing list HOT@openstreetmap.org https://lists.openstreetmap.org/listinfo/hot
