It is the official transformation in gsa and gsb format including an explanatory pdf file...

@SebastianKasan Hi, thanks for the grid. What is the license of the gsb file? Does it allows re-distribution?

At this moment we don't have time to add more transformations in out spare time, but if you need please feel free to submit a patch/PR or consider supporting the necessary work (2/3 hours of work).

Regards

Hi, this is free to use, the exact license is explained in the pdf but it says, any software company can use it as long as the name is attributed....

I will consider the patch thing.
As I understand, QGIS can use NTV2 transformations also with the coordinate manager, is that correct?

@SebastianKasan not sure if I understand this, can you elaborate?

[SebastianKasan]

Apparently you can use .gsb files in QGIS like so:

@SebastianKasan What this plugins does is a slightly different thing:

QGIS can use ntv2 grids when you add layers in a project in order to reproject on the fly that layer using that specific transformation. The added layer is untouched, no changes or copies are made.

The goal of this plugin is to create copies of layers, where a ntv2 transformation is applied.

Ok, but when I save the layers that were reprojected on the fly, I can also set the "on the fly" projection permanent, or not?

yes, but this is a Processing plugin and it allows you to do the save operation in batch mode, meaning that you get copies of many layers in just one operation (not manually one by one).

@SebastianKasan why have you closed this?
