eop root element for generic Earth Observation Product description Earth Obervation Product description Reference to the schema version number used to validate the instance Archiving centre code. Possible values are mission specific and should be retrieved using codespace. PHR : value is a valid station code eop/EOLI : N/A Archiving date time Local archiving id as created by the mission ground segment that may required to allow subsequent order processing Acquisition / receiving station code. Possible values are mission specific and should be retrieved using codespace. Acquisition date time EOLI : orbit (F B b s) EOLI : lastOrbit (F) EOLI : orbitDir (F B b s) Neutral wrsLongitudeGrid to replace track in track/frame, K in K/J, etc. The mandatory attribute "codeSpace" is used to point the reference grid. Neutral wrsLatitudeGrid to replace frame in track/frame, J in K/J, etc. The mandatory attribute "codeSpace" is used to point the reference grid. UTC date and time at ascending node of orbit Longitude at ascending node of orbit. should be expressed in degrees Start time of acquisition in milliseconds from Ascending node date Completion time of acquisition in milliseconds from Ascending node date Actual orbit duration in milliseconds Across Track Incidence angle given in degrees. Along Track Incidence angle given in degrees. Global Incidence angle given in degrees. Pitch angle given in degrees. Roll angle given in degrees. Yaw angle given in degrees. Platform short name (eg. PHR) Platform serial identifier (eg. for PHR : 1A) High level characterisation of main mission types (GEO/LEO) Instrument short name EOLI : instShNm Sensor mode. Possible values are mission specific and should be retrieved using codespace. (eg. PHR : PA, XS or PX). Image resolution Swath identifier (e.g. Envisat ASAR has 7 distinct swaths (I1,I2,I3...I7) that correspond to precise incidence angles for the sensor). Value list can be retrieved with codeSpace. Defines the observation result, i.e. the Earth Observation Product Defines the acquisition footprint, i.e. the region observed by the Instrument Acquisition footprint coordinates, described by a closed polygon (last point=first point), using CRS:WGS84, Latitude,Longitude pairs (per-WGS84 definition of point ordering, not necessarily per all WFS implementations). Expected structure is gml:Polygon/gml:exterior/gml:LinearRing/gml:posList. eop/EOLI : polygon/coordinates (F B b s) Acquisition center coordinates. Expected structure is gml:Point/gml:pos. eop/EOLI : scCenter/coordinates (F B b s) Browse type. Possible values are : THUMBNAIL, QUICKLOOK and ALBUM. Value is mission specific. Value list can be retrieved with codeSpace. Not used by PHR. For MODIS : OPTICAL, THERMAL Indicates if browse is geo-referenced, and thus can be assumed to be displayed directly on a map (in which case should point to a code space for the CRS), when not supplied it is assumed that the browse is provided in "raw" satellite frame of reference Path to the browse image (could be any kind of URL : direct link to the image or WMS/WCS interface), it is assumed that if a client is prepared to "manage" a browse delivered by e.g. WMS they would parse the URL to identify that it contains the OGC standard SERVICE=WMS Indicates if product is geo-referenced, (in which case should point to a code space for the CRS), when not supplied it is assumed that the browse is provided in "raw" satellite frame of reference Path to the actual product data if available online (could be any kind of URL : direct link to the image or WMS/WCS interface), it is assumed that if a client is prepared to "manage" a product delivered by e.g. WCS they would parse the URL to identify that it contains the OGC standard SERVICE=WCS Product version Product size (bytes) allowing the user to realise how long a download is likely to take Processing centre code. Possible values are mission specific and should be retrieved using codespace. Processing date time Composite type of product, if available Method used to compute datalayer. (e.g. Kalman filtering, ROSE) Method version (e.g. 1.0) Processor sofware name (e.g. FastROSE) Processor software version (e.g. 1.0) Processing level applied to the product Native product format Mask type. Possible values are : SNOW, CLOUD and QUALITY Mask format. Possible values are : RASTER or VECTOR Indicates if mask is geo-referenced, and thus can be assumed to be displayed directly on a map (in which case should point to a code space for the CRS), when not supplied it is assumed that the mask is provided in "raw" satellite frame of reference Path to the mask (could be any kind of URL : direct link to the image or WMS/WCS interface in case of RASTER mask; direct link to the file or WFS interface in case of VECTOR file), it is assumed that if a client is prepared to "manage" a mask delivered by e.g. WMS they would parse the URL to identify that it contains the OGC standard SERVICE=WMS Mask defined as a feature collection (in the GML 3.2 sense : a feature collection is a feature having a property derived by extension from gml:AbstractFeatureMemberType). Mandates the following optional gml properties inherited from gml:_Feature : - gml:id attribute - gml:name - gml:boundedBy Note : the upcoming gml:identifier will replace eop:identifier in GML 3.2 Mask member : . Mandates the following optional gml properties inherited from gml:_Feature : - gml:id attribute - gml:name - gml:boundedBy Note : the upcoming gml:identifier will replace eop:identifier in GML 3.2 Mask type. Value list can be retrieved with codeSpace Mask member extent. Expected structure is gml:Polygon/gml:exterior/gml:LinearRing/gml:posList with 0 to n gml:Polygon/gml:interior/gml:LinearRing/gml:posList elements representing the holes. Container for ad-hoc metadata that does not merit a mission specific schema or extension, the localAttribute describes the name of the attribute Container for ad-hoc metadata that does not merit a mission specific schema or extension, the localAttribute describes the value of the attribute Identifier for metadata item, includes ground segment codespace to guarantee uniqueness within eop : urn:eop:GS:CollectionId:ProductId Digital Object Identifier identifying the product Collection identifier Refers to product status. PHR : always "ACQUIRED" Used to distinguish at a high level the appropriateness of the acquisition for "general" use, whether the product is a nominal acquisition, special calibration product or other. Values: - NOMINAL - CALIBRATION - OTHER More specific information (i.e. platform and sensor specific values) are expressed within the imageSubType tag. The mission specific type definition should refer to mission/ground segment dedicated codeSpace. Describes product type in case that mixed types are available within a single collection. This is ground segment specific definition Must be expressed in percents. EOLI N/A (attTypes/attName ?) Indicator to know how the quality quotation has been calculated. From GML 3.2 draft
