The OGC API - Coverages draft specification defines a Web API for accessing coverages. A coverage is a "function which returns values from its range for any direct position within its domain" (ISO 19123-1:2023). Coverages are represented by some binary or ASCII serialization, specified by some data (en­coding) format. Arguably the most popular type of coverage is that of a gridded coverage. Gridded coverages have a grid as their domain set describing the direct positions in multi-dimensional coordinate space, depending on the type of grid. Satellite imagery is typically modeled as a gridded coverage, for example.
