(2)Low cost of data acquisition: the drone operation cost is much lower than satellites and manned aircrafts, as well as its demands for purchase and personnel technology, and easy daily maintenance, all which greatly reduces the data acquired cost.
(2)Strong guarantee for safe operation: the drone adopts autonomous and ground remote control work mode, ensuring the safety of pilots and ground personnel by flying into high-risks area for work instead of human.
(3)High data precision: images acquired by the drone has higher image resolution because of drone low flight altitude, which enables it to observe the ground detailed changes on a small spatial scale, to make big scale drawings and to monitor the impact of human activity to environments.
(4)Quick response to emergency: the drone is low restricted to its take-off and landing space because of its small size, light weight, easy operation; it is able to make quick launch in a short time and acquire the data rapidly.
(5)Acquire data in the cloudy day: the drone can fly below the cloud, making up the disadvantage of the satellite optical remote sensing that can not acquire the image data because of cloud covering; it can work even in the cloudy day.
(6)Large area and long flight time monitoring and surveillance on fixed point and fixed area: after the waypoint has been flied, new waypoint can be uploaded real time for system continuous work, no need to input the new area monitoring points again after landing.
UAV remote sense system use in environment protection
UAV remote system features for low cost, high security, high mobility and resolution, enabling it great advantages in environment protection area. UAV remote sense system plays its powerful technology support in environment protection management construction project, environment monitoring, environment detection, environment emergency and ecological protection.
Traditional environment monitoring has certain limitation by using point monitoring to estimate the environment quality of the whole area. On the contrary, drone is able to fast check the environment situation because of its wide sight and continuous work.
(1)Water pollution area: the spectral images by virtue of the multi spectral imaging sensor can be used for direct identification of pollution source, pollution mouth, visible floating objects and so on. The distribution diagram, as the basis of environmental evaluation and environment detection, can be used to monitor the surface water environment quality roundly by offering the thematic map of water eutrophication, algal bloom, water transparency, suspended matter and the pollution of sewage mouth and so on, thus to achieve better monitoring on the pollutants of water quality characteristics.
(2)Atmospheric pollution: the long-term tracking monitoring on air pollution can obtain three-dimensional distribution data of atmospheric pollutant concentration, such as PM2.5, which offers more precise data for haze forecast, prevention and treatment. At present, the air pollution monitoring mainly focuses on the ground, which is hard for us to learn about the haze formation, disappear and diffusion rule.
The drone mounted with gas detection device makes collection and analysis on the atmospheric pollution at height altitude, satisfying the atmospheric data detection device demands for miniaturization, high precision and real time.
2.Environment emergency use
The drone can fast fly to the pollution accident area to make dimensional surveillance on the accident site, the pollutant emission and the distribution of nearby sensitive points by overcoming the traffic jam and dangerous factors in face of environment emergency cases. The image platform mounted on the drone transmits the real time video information, and monitor the accident process to offer precise information for environment protection decision making. The drone enables the environment protection department to learn more about the emergency events comprehensively, to make faster response to events and to make relevant personnel cooperation more adequate with the decision making more reasonable. What is more, the drone for environment emergency not only reduces the work difficulty, but also offers a better security for the staff.
3.Ecological protection use
Natural reserve and drinking water reserve and so on special protection area are always the key work of all level environmental protection departments. Worse, it is hard to make comprehensive and detailed ecological protection because of big reserve area, remote place with bad traffic conditions. However, the drone can solve the above problem easily. The environmental department can clear learn about the dynamic evolution of the plant ecological environment in reserve areas by using the drone to acquire the remote sensing images each year at the same time, and making analysis of the yearly images or the comparison of the plant coverage rate. The high resolution images can be used to identify the mutual substitution of different plants, serving as the reference for the plant ecological research. The dynamic evolution of the intra-area plant ecological environment is the dual result of natural factors and human activity. If the natural factors remain the same, while accompanied with greater human activity within or nearby the area, the yearly images also offers a basis of human activity impact on plant ecology. When the natural reserve and drinking water reserve are illegally encroached, the drone can make a timely detection, with the images regarded as the evidence for ecology protection law enforcement.
4.Environment monitoring use
At present, it is not easy to make environmental monitoring on the complex industrial pollutants because of its frequent changes, the heavy monitoring tasks without enough personnel and relatively simple supervision model. However, the drone can observe the pollutant source distribution, the emission status and project construction situation at a macro level, offering a decision basis for environmental monitoring; At the same time, the drone monitoring platform makes detection on the sewage draining exist for real time fast tracking on the abrupt environment pollution accidents, catching the illegal pollutant source for evidence collection, offering a timely and high efficient technology service for environmental monitoring law enforcement.
