"WebGISGeoJSON格式（RFC7946）解析和定义原文详解"

The document "WebGISGeoJSON Format Specification (RFC7946).pdf" is the English version of the standard that defines the GeoJSON format. GeoJSON is a widely used format for encoding geographic data and is commonly used in web mapping applications such as Google Maps and Leaflet. The Internet Engineering Task Force (IETF) has published this document as Request for Comments (RFC) 7946 to standardize the format and ensure interoperability between different systems. The authors of the document are Howard Butler from Hobu Inc., Martin Daly from Cadcorp, Allan Doyle, and Sean Gillies. GeoJSON is a lightweight format for encoding geographic data structures such as points, lines, and polygons in a simple and human-readable way. It is based on the JSON format and supports various geometry types, properties, and coordinate reference systems. This makes it easy to work with and integrate into web applications. The document provides a detailed specification of the GeoJSON format, including rules for structuring geometries, properties, and feature collections. It also defines conventions for representing coordinate reference systems and bounding boxes. By following these standards, developers can ensure that their GeoJSON data is compatible with a wide range of mapping libraries and tools. In conclusion, the "WebGISGeoJSON Format Specification (RFC7946).pdf" document is an essential resource for anyone working with geographic data in web mapping applications. It provides a clear and comprehensive definition of the GeoJSON format, making it easier to create, share, and interpret spatial data across different platforms and systems. Its standardization by the IETF also ensures that GeoJSON remains a reliable and widely supported format in the field of geospatial technology.
