Author Name: Andre Joost (Andre Joost) The CRS mentioned are based on the geographical CRS EPSG:4803 Lisbon(Lisbon), using the prime meridian of Lisbon. The transformation method 5838 from Lisbon(Lisbon) to WGS84 is a Concatenated Operation:
The first step is done in GDAL/QGIS with ```+pm=lisbon

Author Name: Pedro Venâncio (Pedro Venâncio) Hi André, I leave here the insert sentences for tfm 1984 and 1988, with 4803 as source_crs_code.
I tested them and they are working properly. Tfm 1656 was replaced by 1988 so I think it's not necessary. And tfm 1944 is marked as deprecated by EPSG (Error in rX parameter value. This EPSG copy to WGS 84 not replaced as superseded by direct determination Lisbon to WGS 84 (4) (tfm code 1988).) By the way, I think all deprecated transformations should be dropped. I also leave two new transformations, for your consideration:
Thanks!

Original Redmine Issue: 9614
Affected QGIS version: master
Redmine category:projection_support
Assignee: Marco Hugentobler
The datum transformation dialog box does not appear when adding a layer in Datum Lisboa (EPSG 20790 or EPSG 20791) to a project in EPSG 3763. If the layer is in Datum 73 (EPSG 27493), the dialog box appears as expected.
I attach a sample data. To reproduce, load first rgn_etrs89_marco_2012.shp (EPSG 3763), then rgn_dlx_marco_2012.shp (EPSG 20791) and finally rgn_d73_marco_2012.shp (EPSG 27493).
