The mosaic should be represented as a single OrthoimageCoverage instance, without additional
instantiations.
Component Number of instances Comment
OrthoimageCoverage 1
Seamline 0 Not populated
OrthoimageAggregation 0 Not applicable
D.2.4 Mosaic of several input images without information about seamlines
(with tiling)
This case is similar to the previous, except that the mosaic of several input images is divided into six
tiles, so that the range set of each tile is stored in only one image file.

Tiling does not affect the structure of the data set. Indeed, the mosaic should be represented as a
single OrthoimageCoverage instance.

D.2.5 Mosaic of several input images with seamlines (no tiling)
The orthoimagery data set consists in a seamless orthoimage resulting from the mosaicking of several
input images. The delineation of the seamlines with the acquisition dates of the input images are
available. The range set of the full mosaic is embedded in a single image file.
