6. The QT Railway and QT Highway have recently been built to connect Qinghai with Tibet. This has made the mountainous region of Tibet accessible to the rest of China. The endangered Tibetan antelope migrates over 300 km each year to give birth to a single calf. The QT Railway and QT Highway cross this migration route, see Figure 2.

Seasonal migration and home ranges of Tibetan antelopes (Pantholops hodgsonii) based on satellite tracking. Int. J. Zool. Res., 13: 26–37. © 2017 Karina Manayeva et al.] The building of the QT Railway and QT Highway presents potential dangers to both the antelopes and the public travelling through this nature reserve. To understand more about the antelopes’ migration patterns, some antelopes have tracking devices attached. Using the information from these tracking devices, a 2D visualization model can be developed and updated in real time.
