Due to the large-scale crop area vehicle survey system, it is a complex dynamic measurement and control system. Therefore, the system's requirement for the auxiliary software design of the farmland area measuring instrument is that the software must complete the control, calculation and processing of the system within one sampling period. That is, it has real-time processing functions; it adopts a module structure to write common programs into subroutines to save memory and enhance its versatility; integrates various software development and maintenance methods, reasonably divides the functional scope of the tools, and makes them harmonized. Work; should have good secondary development and expansion capabilities.
Selection of GIS Development Software in Farmland Area Measuring Instrument . MapObject can be easily combined with other visual development language tools, using its unique map controls to achieve the desired development goals, providing the most common functions with minimal interfaces, and even the dynamic nature of GPS. At the same time, it is easy to understand and extend, with great flexibility to establish user interfaces, and can also be built directly on the MFC library to optimize execution. It can be seen that the combination with VC++.NET is an effective tool for rapid development of executable programs for end users.
The application of the above-mentioned large-scale crop area vehicle survey method to the aid of the farmland area measurement instrument is based on a certain mathematical statistical method and theoretical foundation. It has great technical improvements for the determination of farmland area. The timely and accurate response and statistical techniques for various current agricultural agricultural research projects are of great concern to the various agricultural sectors. At the same time, these advanced farmland area measuring instruments and scientific and technological technologies are important for rural economic development and major food security. The solution of the problem has an important role and significance.
The Application of Farmland Area Measuring Instrument and Vehicle Survey System
The application of space technology, including statistical methods, specifications, and evaluation of data accuracy, are all problems that need to be solved in determining crop area. At present, China mainly obtains information on the country's crop planting area through the ground sampling of the Statistics Bureau and statistical data reported by the Ministry of Agriculture. RS-based, GIS-based, and GPS-based farmland area measuring instruments are used to monitor crop areas. Although timely and objective spatial information technologies are available, due to the lack of standard methods for operation and accuracy assessment, they have not yet been formally incorporated into the government statistics system.
