Currently, satellite remote sensing plays an important role in agricultural resource investigation, agricultural production process monitoring, and rural habitat environment monitoring. Technological developments have allowed agriculture and rural areas to embark on a new journey of development.
Satellite remote sensing monitoring has the characteristics of large monitoring area, wide range, and high accuracy. As a new means of ground monitoring, actual planting areas of a certain crop nationwide can be observed through satellite remote sensing monitoring, and yield estimates can be made by combining the yield per variety.
At the same time, high-precision and high-timeliness satellite remote sensing monitoring can also observe long-term crop growth, and continuously adjust estimated data based on crop growth.
In addition to monitoring crop growth, satellite remote sensing can also monitor soil moisture content of cultivated land, bulk agricultural crop diseases, and provide scientific monitoring methods and decision-making basis for agricultural planting due to its wide monitoring range and other characteristics.
As an alternative means of ground observation, satellite observation can monitor the planting conditions of a certain plot of land in different years. Based on the spectral features of the plot of land presented in satellite images at different periods, the land use of the plot of land at different periods can be understood. Regarding land presenting bare ground features, precision and rapid identification can be achieved, and non-agricultural activities can be strictly prohibited on cultivated land to protect agricultural land resources.
With the deepening of the application of satellite remote sensing data, agricultural and rural monitoring services utilizing the "integration of heaven and earth" perception technologies as a service tool are constantly innovating with the deepening development of remote sensing data. This technology is used to monitor and regulate rural habitat environment improvement, rural homestead utilization, high-standard farmland construction, and monitoring, providing data support for the digital management and scientific decision-making of agriculture and rural areas.
Remote sensing technology can monitor and analyze multidimensional information such as the location, shape, area, distribution, and even the situation of the farmers of farmland plots, providing farmers with decision-making basis. The intelligent water and fertilizer integrated system automatically controls the supply of water and fertilizer, connecting satellite images with the internet of things, drones, agricultural machinery, and equipments, helping farmers to precisely irrigate, fertilize, and apply pesticides, achieving the goal of reducing costs and increasing efficiency. This has changed our previous production mode that relied on experience and intuition to one that relies on data to encourage agricultural and rural development.
Accelerating the industrialization process of satellite remote sensing information services can help government departments to make macro decisions and better serve the national strategy of "stockpiling grain in land" and national food security strategy, making the development of satellite remote sensing technology go further in the waves of technology and society.
