Feature Description
The rapid advancement of modern information technology is accelerating human society's entry into the big data era. With the widespread adoption of global satellite navigation systems (GNSS) like BeiDou, location information plays an increasingly vital role in various big data applications across economic development, social progress, and daily life.
Developed based on geospatial subdivision theory, the BeiDou Grid Location Code serves as a standardized spatial encoding scheme compatible with BeiDou navigation system terminals. Sharing common origins with the GeoSOT model (Geographic Spatial Orbit Temporal grid model), this encoding system aligns with the BeiDou system's positioning accuracy while balancing human and device usability. It serves as a crucial complement to traditional latitude-longitude coordinate systems.
Integrated with BeiDou and its augmentation systems, BeiDou Grid Codes provide users with a novel spatial location service paradigm, significantly enhancing the efficiency of big data management, computational analysis, and query integration. The widespread adoption of BeiDou Grid Codes will not only benefit high-precision location services, IoT applications, and smart city development, but also holds strategic significance for national informatization, modernization of governance capabilities, and establishment of China's big data ecosystem.
This method generates corresponding BeiDou two-dimensional grid codes for each geometric object in datasets. For detailed subdivision rules and encoding specifications, refer to the national standard "BeiDou Grid Location Code (GB/T 39409-2020)".
