FPWD: Overview of the CoverageJSON format

Overview of the CoverageJSON format

https://www.w3.org/TR/2017/WD-covjson-overview-20170509/

Abstract


This Note describes CoverageJSON, a data format for describing "coverage" data in JavaScript Object Notation (JSON), and provides an overview of its design and capabilities. The primary intended purpose of the format is to enable data transfer between servers and web browsers, to support the development of interactive, data-driven web applications. "Coverage" data is a term that encompasses many kinds of data whose properties vary with space, time and other dimensions, including (but not limited to) satellite imagery, weather forecasts and river gauge measurements. We describe the motivation and objectives of the format, and provide a high-level overview of its structure and semantics. We compare CoverageJSON with other "coverage" formats and data models and provide links to tools and libraries that can help users to produce and consume data in this format. This Note does not attempt to describe the full CoverageJSON specification in detail: this is available at the project webite.
