WorldToEcef and EcefToWorld free functions
GeocentricTransform<TDirectionOfMapping, TScalarType> is a
otb::Transform that can be used to transform geographic points to and from ECEF points.
In some cases it is interesting to perform the conversion without having to instantiate a transform object, for example if only one conversion is required. This MR implements otb::Projection::WorldToEcef and otb::Projection::EcefToWorld as free function. These functions are used internally by
See this discussion
The functions are implemented in
Modules/Core/Transform/GeocentricTransform.h/hxx and are templated over the scalar type and over a struct holding the ellipsoid parameters used for the computations. By default the WGS84 ellispoid parameters (new struct
otb::Projection::WGS84Ellispoid) are used. Prior to this merge request, these parameters were stored in
Additionally, this MR removes useless map projection instantiation in the
GeocentricTransform constructor, which is now defaulted.
