INSPIRE - Process step

[mjanez]

C.7.4. Process step

Metadata element name	Process step
Reference	INSPIRE Data specifications, sections 8.3.x
Definition	Information about an event or transformation in the life of a dataset including the process used to maintain the dataset
ISO 19115 number and name	84. processStep
ISO/TS 19139 path	dataQualityInfo/DQ_DataQuality/lineage/LI_Lineage/processStep/
INSPIRE obligation / condition	optional for dataset and dataset series; not applicable to services
INSPIRE multiplicity	[0..*] for dataset and dataset series
Recommended for themes	Elevation, Orthoimagery
Data type (and ISO 19115 no.)	86. LI_ProcessStep
Domain	This is a complex type (lines 87-91 from ISO 19115). The description (87., free text) property shall be provided.
Example
Comments	ISO 19115 lists several elements which build LI_ProcessStep. For the purpose of theme-specific metadata according to the INSPIRE Data specifications the element listed above is sufficient. Note that the path for dataQualityInfo/DQ_DataQuality/lineage/ will already exist in metadata because of being used for carrying information about lineage itself (see 2.7.1). Therefore an addition of these information into the same entity of LI_Lineage may be useful.
Comments on theme ELEVATION	This metadata element aims to supplement the Lineage metadata element defined in Regulation 1205/2008/EC with a precise description of a process or operation that has been applied to the elevation dataset. As illustration, the following processing steps may be traced here: * Data acquisition. * Data editing. For vector data: * Aero-triangulation. * Stereo-plotting. For grid data: * Grid calculation / sampling. Note that such information may convey, most often implicitly, supplementary indications of the expected quality of a dataset, which often depends on the nature of the production process. In the case of the data acquisition process it is important to highlight any known limitations which may lead to quality problems, for example the description of the geographical areas where the reliability of geographic information is reduced or limited due to limitations of the data capture technology used. Information relative to the geometry of low reliability areas (e.g. links to elsewhere such geometries may be obtained) can be particularly helpful to assess the accuracy and the reliability of the elevation data set.
Comments on theme ORTHOIMAGERY	This metadata element aims to supplement the Lineage metadata element defined in Regulation 1205/2008/EC with a precise description of a process or operation that has been applied to the orthoimagery dataset. For example, the following processing steps, which are common in orthoimagery, may be traced here: * data acquisition * aero/spatio-triangulation * orthorectification * mosaicking * radiometric correction Note that such information may convey, most often implicitly, supplementary indications of the expected quality of a dataset (e.g. the radiometric aspect of a mosaic), which often depends on the nature of the production process.
