struct mrpt::topography::TDatumHelmert3D_TOPCON

Overview

Same transformation as TDatumHelmert3D, but with the affine transformation coefficients given directly, following the convention used by TOPCON equipment/software: [ X Y ]_WGS84 = [ a b; d e ] [ X Y ]_local + [ c f ], Z_WGS84 = Z_local + g.
