ITK spatial objects in OTB
ITK spatial objects, and in particular
itk::LineSpatialObject, are only used in a few classes of the OTB: the module Core/spatialObjects and the filters using this module:
The module and those four filters are not used anywhere else in OTB. In OTB we already have OGR to model geometries, so I think otb::SpatialObjects should be removed and the filters should be updated to use ogr instead (or maybe removed if they're not useful anymore)
This was already discussed in #1763 (closed)
in ITK 5.0, there is a major API change for spatial objects, so we need to make a decision about
otb::spatialObjects as soon as possible.
