22 August, 2013 - The Open Geospatial Consortium (OGC®) is seeking comments on the candidate OGC Web Coverage Service (WCS) Interface Standard Interpolation Extension.

The OGC Web Coverage Service (WCS) Interface Standard defines an open standard interface to access multi-dimensional spatio-temporal coverages, such as sensor data, satellite imagery, image time series, point clouds, and meshes. The candidate WCS Interpolation Extension document specifies parameters to the WCS GetCoverage request that provide control over interpolation of a coverage during its server-side processing. WCS has a core mission to preserve data quality, and by default always delivers original, unaltered data. Whenever interpolation – which may impact accuracy – is necessary, this extension allows clients to specify the interpolation method that the server shall apply. This can even be indicated individually per axis, such as “perform linear interpolation along latitude and longitude, but perform nearest-neighbor interpolation along time.”

An overview of the complete WCS suite is available at

All OGC standards are free and publicly available. Download the candidate OGC WCS Interface Standard Interpolation Extension. Comments are due by 22 September, 2013.

The OGC is an international consortium of more than 480 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC Standards support interoperable solutions that "geo-enable" the Web, wireless and location-based services, and mainstream IT. OGC Standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled. Visit the OGC website at
