This plugin allows QGIS user to do easily direct/inverse Datum transformations (for vectors and rasters) using NTv2 grids. Available transformations will be the ones that are supported by NTv2 grids that will be possible to redistribute legally with the plugin itself.
The plugin needs QGIS 2.8 to work.
This plugin is directly derived from https://github.com/qgispt/processing_pttransform originally developed by Alexander Bruy, Pedro Venâncio and NaturalGIS (http://www.naturalgis.pt/), with the support of the Portuguese QGIS user group (http://www.qgis.pt/).
If you have a NTv2 grid that can be legally redistributed and you would like to have it added to this plugin please file a feature request here:
