Land and resources remote sensing platform of flight

A, unmanned aerial vehicle (uav) application in investigation of land and resources

Land and resources including the land resources, mineral resources, Marine resources, water resources, climate resources, biological resources and tourism resources, such as the application of aerial remote sensing in land and resources survey generally cover territorial control planning and management, environment and disaster monitoring, hydrogeology, engineering geology exploration, construction project site selection, line selection and urban planning, and other fields. Unmanned aerial vehicle (uav) flight platform in the field of remote sensing survey of land and resources play its own advantages, low cost, low speed, cruising distance, high reliability of uav low-flying mission, the operator can easily control the aircraft on the ground of the flying route and altitude.

1. The unmanned aerial vehicle (uav) for urban planning survey

Unmanned aerial vehicle (uav) with a digital camera to fly over the city and provide basis for the development of urban planning information system. Widely used in building density distribution of study, construction site investigation, central city Jane room leaking tents, construction of road condition, the outdoor parking lot survey, the spatial distribution of landfill, sewage disposal and reconstruction project of complement argument, image data provided for factory planning or modification, etc. Unmanned aerial vehicle (uav) in addition to the application, development trend and the change of transformation in the city, the city map update, can also be used for city present situation investigation, such as land use, cadastral, transportation, tourism resource investigation, draw the distribution of urban greening, soot pollution distribution, distribution, water pollution and the urban environment, such as "three wastes" pollution, geological disasters, urban public safety monitoring.

2. The unmanned aerial vehicle (uav) used in exploitation of mineral resources investigation

Our country mining area development caused the destruction of the ecological environment; Mineral resources planning implementation is not clear, the lack of objective and valid data; Because of the lack of real-time monitoring violations occurred frequently. Unmanned aerial remote sensing mining mineral mines location (well location), the mining state (or close) mining, mining minerals (coal, iron,...), (), underground mining method, covers the range and scope of land types, solid waste accumulation and occupation of land types, etc. Unmanned aerial vehicle (uav) can also be observed mineral resources development caused by disasters. Including the scope of the ground subsidence, ground fissure length, sunken pit location, scope of mountain in crack (collapsed), position the collapse, landslide and debris flow location, channel length (location) and spontaneous combustion (coal gangue) range, etc. Detection of mine ecological environment information. Including land destroyed range, damage to vegetation, scope of scope of scope of dust pollution, water pollution, desertification and land reclamation area and the effect of mine environment management. Unmanned aerial vehicle (uav) of low altitude remote sensing with ground management software can also be for the overall situation of mineral resources development decision support system.

3. The unmanned aerial vehicle (uav) used for agricultural land resources and agricultural resources

assessment

Uav remote sensing can be quickly estimated crop planting area, crop condition monitoring and yield forecasting, and irrigation crops drought monitoring and used for agricultural natural resource management. Interpretation, judgment, the problems in the agricultural production, such as plant diseases and insect pests, soil salinity, soil nutrition, water pollution and so on. Agricultural ecological environment change monitoring: grassland degradation, land desertification, soil erosion, water environment pollution monitoring environmental resources and agricultural water supply planning.

4. The unmanned aerial vehicle (uav) for remote sensing geological disasters

Drones can be large engineering, railway and highway in the mountains, mountain towns along the suspicious landslide area on the area such as remote sensing, geological environment research, landslide disaster danger evaluation, prediction and assessment, disaster reduction and prevention, provide important basis for disaster relief and reconstruction work. At present mainly to collapse, landslide and debris flow of geological disaster investigation and remote sensing monitoring technology has been basically mature, such as using uav remote sensing to around the dam site and reservoir area landslide distribution, scale and development environmental investigation, assessment of dam site and reservoir bank stability, provide the basis for water and electricity engineering construction materials, etc.

5. Drones used in railway construction

Uav remote sensing application in railway construction including various thematic content by using remote sensing image interpretation and aerial mapping, scheme comparison for the route and the survey is designed to provide information, including the use of geological, hydrological interpretation of remote sensing image, to match the route scheme comparison. By using remote sensing image has carried out a large number of aerial mapping work, in order to meet the needs of the early railway design in drawing. The application of uav remote sensing technology in railway construction project of the selected lines and crossing scheme, late in the engineering of debris flow, collapse, landslide investigation can play a good role.

6. Drones used in archaeological investigations

Unmanned aerial vehicle (uav) through the air from different angles and different time observation and photography, using morphology, terrain shadow, flood, frost and snow, soil moisture and vegetation all sorts of signs, such as some of the characteristics of interpretation out of the ground or underground site. Under favorable conditions, the underground ruins of certain information can also emerge through interference with the ground information. By the extension of aviation remote sensing survey and field of vision, it is easy to on the ground looks messy some ruins, ruins, through after "interpretation symbol" to identify them. Especially in the traffic inconvenience, even it is hard to reach, natural conditions, complex landform areas (such as some mountain, desert, plateau, water network region), archaeological investigation with remote sensing image interpretation method is the fastest way. This method applied in foreign countries is very common, also has been very successful. Such as in Bavaria in Germany by aerial remote sensing archaeology investigation, increase the number of ancient ruins for more than a third. Who plate made in our country, in the late 80 s, accurately create nearly thousand kilometers long, the snow under the cover of "greatwall" (also called into jisr khan sidewall or phnom penh fort) in a while. Fort images, the side of the moat, horse-refraining pits, and the garrison city of fort border, have an unobstructed view, their images, received the unexpected effect, this is can't be matched by the archaeological investigation of the field.

7. Unmanned aerial vehicle (uav) for coal fire investigation

Spontaneous combustion of coal seam is one of common disaster in north China coalfield, lost a lot of coal resources. According to existing data, there are many coal seam spontaneous combustion phenomena, the loss of about 200 million tons of coal each year, accounting for 20% of the total production in the whole country at present, release a large amount of harmful gases at the same time. Such as: our fleet, H2S, CO and so on, seriously polluted the atmosphere, causing the ground subsidence, threatening the safety of mine production. Unmanned aerial vehicle (uav) coal fire investigation aims to provide specific mining area coal seam burning information and data, to formulate concrete extinguishing fire plan, estimated cost, predict the combustion trend, check the fire fighting service effect.

Second, the company advantages and characteristics of uav remote sensing

1) stable platform for the flight, flight speed slow, low-flying, suitable for large scale aerial photography;

2) digital yuntai combined with GPS, target accurate positioning;

3) automatic take-off and landing, leave out the trouble flying operation training for many years;

4) orthographic yuntai and multi-angle imaging, high precision shooting;

5) in harsh natural conditions the feasibility of the executive system;
