Web Coverage Service (WCS) Support

This chapter describes the Oracle Spatial implementation of the Open GIS Consortium (OGC) standard for Web Coverage Service Interface Standard (WCS), which, supports retrieval of “coverages” (according to the OGC, “electronic encoding of geospatial data, that is, digital geospatial information representing space and time-varying phenomena”).

Note:

The Oracle Spatial implementation will be referred to as Web Coverage Service, or WCS.

Web Coverage Service (WCS) enables electronic retrieval of geospatial data as “coverages.” WCS provides data and descriptions, a syntax for querying the data, and the ability to return data on which you can perform various operations (visualize, interpret, extrapolate, and so on). WCS supports the storage of both GridCoverage (GeoRaster object without coordinate reference system) and RectifiedGridCoverage (GeoRaster object with coordinate reference system and georeferenced with an affine transformation) raster types

Oracle Spatial implements the following OGC standards.

Oracle WCS also extends the OGC standards to support all GDAL-supported image or raster features as output format in a GetCoverage request.

Note: Before you use WCS, be sure that you understand the concepts described in Introduction to Spatial Web Services, and that you have performed any necessary configuration work as described in that chapter.
