A multi-level unified coding system for low-altitude airspace

Abstract

This invention relates to airspace coding, specifically to a multi-level unified coding system for low-altitude airspace. The system includes a coding hierarchy architecture module, which designs and constructs an eight-level coding architecture from the national level to the building level; a coding inheritance and short code setting module, which designs inheritance logic to achieve reversible traceability of codes and designs short code rules to improve coding efficiency; a coding fusion module, which combines a planar coordinate framework and altitude coding to achieve integrated coding of planar and altitude spaces; a coding splicing and storage module, which designs coding splicing rules, file naming conventions, directory hierarchy structures, and unified attribute fields to facilitate system storage, parsing, front-end loading, and spatial indexing; and a multi-standard compatibility module, which establishes compatibility conversion rules between grid data and various existing standards to ensure seamless integration with existing industry data systems. The technical solution provided by this invention overcomes the shortcomings of achieving accurate low-altitude airspace division, efficient traceability, and cross-industry data interoperability.
