Remote sensing is no longer just used for monitoring, and the development of agricultural digitalization also relies on it

The spatial distribution map of crops is an important basis for scientifically grasping the situation of regional agricultural production, optimizing the allocation and utilization of agricultural resources, and adjusting the planting structure of crops. The medium and low spatial resolution remote sensing data is a widely used data source in regional crop spatial distribution mapping or planting structure monitoring. It has the characteristics of wide observation range, multiple spectrum bands and high time frequency, which can better describe the growth of crops under complex planting structures. Developmental phenological characteristics. The following editor will take you to understand the inseparable relationship between remote sensing technology and agricultural development. Remote sensing as a tool for agricultural monitoring“fiery eyes”As we all know, by analyzing crop remote sensing image data, we can accurately and objectively obtain crop planting area, distribution, agricultural disasters, etc., and can predict crop yield. This is like putting a pair of eyes on agricultural production. Among them, we should be familiar with the three-dimensional display system of agricultural remote sensing information in Henan Province. This system can display the planting distribution of autumn crops. The planting area and structure of various crops are clear at a glance, which can not only provide a reference for government decision-making, but also predict the market in advance. Supply, and guide relevant businesses to reasonably arrange human and material resources in the purchase of agricultural products. In addition to monitoring crops, remote sensing technology can detect agricultural disasters in time.“fiery eyes”. Taking drought monitoring as an example, in the past, a large number of personnel were required to collect data point by point with soil detectors, and then report it layer by layer, which was inefficient and costly. Various human factors would also affect the objectivity of the data. The agricultural remote sensing monitoring technology has high efficiency and large scope, and realizes accurate and objective disaster monitoring data, which can be used by agricultural decision-making departments to respond in time and provide information support for the formulation of drought relief measures. At the same time, the application of remote sensing monitoring technology to agricultural insurance can improve the accuracy and efficiency of agricultural underwriting and claims settlement, and provide help for farmers to obtain insurance damage compensation as soon as possible. Looking at the development of digital agriculture from the perspective of remote sensing Digital agriculture is the organic combination of remote sensing, geographic information system, positioning system, mechatronics and agriculture, and it is the concentrated expression of the application of remote sensing technology in the field of agriculture. Digital agriculture is an information-intensive technology, which has extremely high requirements for information acquisition and processing technology, and is also an inevitable result of the development of information technology to a certain extent; in addition, digital agriculture is also an environment-friendly technology, because pesticides in agricultural production. Excessive application of chemical fertilizers and fertilizers will cause serious environmental pollution, and excessive agricultural cultivation will also lead to environmental damage such as soil erosion. Digital agriculture is an advanced stage of agricultural modernization, and it is the only way for my country to move from a large agricultural country to a powerful agricultural country. In recent years, the development of digital agriculture in my country has achieved remarkable results, but it also faces many problems that need to be solved urgently. In this regard, it is necessary to take targeted measures, aiming at the main direction of agricultural and rural modernization, providing strong informatization support, and providing new momentum for the high-quality sustainable development of agriculture, so that farmers have more sense of gain, happiness, sense of security. As early as October last year, Pinduoduo announced a strategic cooperation with the National Agricultural Information Engineering Technology Research Center to jointly build“Smart Agriculture Collaborative Innovation Center”. Agricultural remote sensing is an important part of this cooperation. The agricultural informatization platform built by Pinduoduo, Huawei and the government in cooperation with the government also revolves around remote sensing data services. For these giants who want to make achievements in the upstream of agriculture, the application scenario of agricultural remote sensing is a suitable entry field. On the one hand, as a spatial information processing technology, remote sensing can quickly count basic agricultural resource information and display it through visualization tools such as maps. This is the first step in agricultural informatization, and it is also the basis for more digital tools and management methods to be applied to agricultural production. On the other hand, with the expansion of the demand market, the existing technologies and services have not yet fully met the market's requirements for refined services. A large amount of agriculture-related data is still scattered in the hands of the government, university scientific research institutions, technical service providers and other parties, and the industry lacks the motivation to integrate.
