The NTv2 transformation from Datum Belge72 to Datum ETRS89 is available for ArcGIS® Desktop 10.7, ArcGIS® Pro 2.3 and ArcGIS® Enterprise
The Belgian National Geographical Institute provides to users on its website an NTv2 grid for the transformation of geographical data expressed in the Datum Belge72 to the ETRS89 Datum.
This transformation grid has been integrated by ESRI with their new version of ArcGIS software.
Given the amount of data needed for the transformation grids available for different countries, these transformations are contained in a module to download and install separately.
This module is called “ArcGIS Coordinate Systems Data”.
