Mapping is not always possible with kinematic GPS. There are many situations in our applications where we can not use GPS, such as in canyons, under heavy foliage. A modern and accurate total station is then the best alternative.
We are equipped with a Leica TPS1200 + Total Station for accurate mapping. To perform the measurements, one person is enough to apply a reflector with remote control. Even without a reflector, it is no problem to map up to distances of several hundred meters.
