Which format is commonly used for geospatial data exchange?

GeoJSON is a widely adopted format specifically designed for encoding a variety of geographic data structures. It is built upon JSON (JavaScript Object Notation) and is particularly suitable for web applications because of its lightweight and easily readable nature. This format allows for the representation of geospatial features along with their attributes, making it ideal for exchanging spatial data between systems, especially in conjunction with web services and APIs.

GeoJSON supports a variety of geometric types, such as points, lines, and polygons, which are essential for depicting spatial features. Its adherence to the JSON standard makes it compatible with many programming languages and frameworks, facilitating integration into applications that handle geospatial data. Furthermore, many modern GIS tools and libraries, including those used in web development, support GeoJSON natively, enhancing its popularity for geospatial data exchange.

In contrast, other formats like XML and CSV do not have specialized structures for representing geospatial data or lack native support for complex geometries. XML may be used in some contexts, but it is generally more verbose and less efficient for this purpose. CSV is primarily a tabular format and does not inherently support spatial data types or structures, making it less suitable for geospatial information exchange. HTML is primarily used for structuring web content and
