All this was necessary due to the infestation of the pines caused by nematodes
Drones for monitoring the health of pines. This is what happens in Beijing, in the Yanqing district (northwest of the Chinese capital).
In the city you can see 90 cm long drones, whose autonomy is about an hour and a half, which fly over the areas involved in monitoring. The device can cover an area of over nine square kilometers. The sensor mounted on the drone also has a resolution of 42 million pixels.
The city authorities have already monitored the pests through investigations
These aircraft can automatically acquire a partial image every 100 meters traveled. In this way, hundreds of aerial photos generate a remote monitoring framework in which it is possible to clearly recognize the areas allegedly infested with parasites.
All this was necessary because of the infestation of the pines caused by nematodes, which is considered a cancer for the trees. The infested plants risk death within 40 days of the colonization of these parasites. The city authorities have already monitored the pests through surveys conducted by ecological workers and forest guards.
However, Beijing has a 1,060 square kilometer pine forest, so it was rather difficult to carry out timely and complete monitoring.
