In parallel to the development of the JTG 5-6 plugins for CPG PTD, similar activities in SE42 (CEPT project team under WGSE closed in 2010) were on-going and in the course of the development of the plugins an ambiguity was found with respect to the interpretation of the interpolation between 100 m and 1 km and the 40 m to 100 m (see details in Doc. ECC/CPG11 PT-D(09)024).

Therefore, there was a need to develop two plugins to be made available based on the following figure:

The selection between the two implementations is presented in the GUI of the JTG5-6 below:
