|Definitionskos:definition||This OGC Implementation Standard defines a profile of Observations and Measurements (ISO 19156:2010 and OGC 10-025r1) for describing Earth Observation products (EO products).This profile is intended to provide a standard schema for encoding Earth Observation product metadata to support the description and cataloguing of products from sensors aboard EO satellites. The metadata being defined in this document is applicable in a number of places where EO product metadata is needed.1.In the EO Product Extension Package for ebRIM (OGC 10-189). This extension package defines how to catalog Earth Observation product metadata described by this document. Using this metadata model and the Catalogue Service defined in OGC 10-189, client applications can provide the functionality to discover EO Products. Providing an efficient encoding for EO Product metadata cataloguing and discovery is the prime purpose of this specification.2.In the EO Application Profile of WMS (OGC 07-063r1). The GetFeatureInfo operation on the outline (footprint layer) should return metadata following the Earth Observation Metadata profile of Observation and Measurements.3.In a coverage downloaded via an EO WCS AP (OGC 10-140). In WCS 2.0 (OGC 10-084), the GetCoverage and DescribeCoverage response contains the metadata element intended to store metadata information about the coverage. The Earth Observation Application profile of WCS (OGC 10-140) specifies that the metadata format preferred for Earth Observation is defined by this document.4.Potentially enclosed within an actual product to describe georeferencing information as for instance within the JPEG2000 format using GMLJP2. GMLJP2 defines how to store GML coverage metadata inside a JP2 file. Earth Observation data products are generally managed within logical collections that are usually structured to contain data items derived from sensors onboard a satellite or series of satellites. The key characteristics differentiating products within the collections are date of acquisition, location as well as characteristics depending on the type of sensor, For example, key characteristics for optical imagery are the possible presence of cloud, haze, smokes or other atmospheric or on ground phenomena obscuring the image. The common metadata used to distinguish EO products types are presented in this document for generic and thematic EO products (i.e optical, radar, atmospheric, altimetry, limb-looking and synthesis and systematic products). From these metadata the encodings are derived according to standard schemas. In addition, this document describes the mechanism used to extend these schemas to specific missions and for specific purposes such as long term data preservation.|
