While it does appear to be similar at first look, they are actually different technologies. C3 requires a plane / helicopter / UAV to fly (very low, 500m) over an area to capture the data, then it can be processed into a 3d map. Seems similar to street view, but from the air. Takes continuous images of an area. Vricon however is using satellite imagery taken from just a few angles to then generate the 3d data. This means it can be done anywhere in the world, without needing to fly there. Which means the process could be started almost immediately, and without endangering anyone if the area is dangerous or remote.
