Increased security of photogrammetry technologies (flights), raising the quality and lowering the cost of labor and also on subsequent developments and updates, which are the result, it is always current problems. The possibility of use 3D modeling for spatial analyses from low-height aerial images realized by unmanned, small aerial platforms (UAVs), equipped with small digital cameras seems to be worthy of attention. The intention of the author of this work is the problem of use 3D modeling terrain images defined as lowheight, which means images recorded with unmanned platforms (UAVs) with low-height altitude not exceeding 100 meters above the average level of the area.
