-- Name -- orthoimage coverage -- Definition -- Raster image of the Earth surface that has been geometrically corrected ("orthorectified") to remove distortion caused by differences in elevation, sensor tilt and, optionally, by sensor optics. -- Description -- NOTE 1 An orthoimage coverage is a continuous coverage based on a rectified quadrilateral grid. It is provided with an interpolation method to evaluate value records at any direct position within its domain. NOTE 2 An orthoimage coverage can be derived from one single input image or from different input images which have been mosaicked and merged together. NOTE 3 An orthoimage coverage may be an aggregation of subsets extracted from other orthoimage coverages. For the avoidance of data duplication, this kind of aggregated orthoimage is dynamically constructed thanks to references to the contributing orthoimage coverages .
-- Name -- aggregated mosaic element -- Definition -- Mosaic element relating to several input images that share the same acquisition time at a given level of definition (e.g. day, month). -- Description -- NOTE The geometry of an aggregated mosaic element corresponds to the union of the contributing areas, in the mosaic, of several input images.
-- Name -- mosaic element -- Definition -- Abstract type identifying both the contributing area and the acquisition time of one or several input images used to generate a mosaicked orthoimage coverage. -- Description -- NOTE The main purpose of this feature type is the provision of a mechanism for describing the spatial distribution of the acquisition dates and times over a mosaicked orthoimage. The acquisition time can be supplied either for each individual input image, or for sets of input images grouped together according to temporal criteria.
-- Name -- single mosaic element -- Definition -- Mosaic element relating to a single input image. -- Description -- NOTE The geometry of a single mosaic element corresponds exactly to the contributing area, in the mosaic, of the single input image.
-- Name -- orthoimage aggregation -- Definition -- Geometrical characteristics of the orthoimage aggregation.
-- Name -- interpolation method value -- Definition -- List of codes that identify the interpolation methods which may be used for evaluating orthoimage coverages. -- Description -- NOTE 1 This INSPIRE-governed code list is derived from the code list CV_InterpolationMethod specified in ISO 19123. CV_InterpolationMethod is not used as such because not actually implemented. NOTE 2 Example values: nearestneighbor, bilinear, biquadratic, bicubic, etc...
