From 4f5a82556291b957720c719228686714ddb13ed7 Mon Sep 17 00:00:00 2001 From: crayfish66 <151830093+crayfish66@users.noreply.github.com> Date: Fri, 22 Nov 2024 09:35:21 +0100 Subject: [PATCH 1/2] Update georeferencer.rst Three additions: 1) adding "GCP" before "point" in 2 entries in a legend to the buttons, for consistency with the remaining legend entries (although I'm aware, that the final "P" in "GCP" abbreviation also mean "Point" - but this regards all resp. entries); 2) adding explanations, what "Link QGIS to Georeferencer" and "Link Georeferencer to QGIS" buttons actually do (it was not written anywhere and I had to look for this over the Net for a while) 3) adding a tip, how to avoid switching between "Pan" and "Add" or "Move GCP Point" when moving from one location to the other (I also did not find it at once). --- docs/user_manual/working_with_raster/georeferencer.rst | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/docs/user_manual/working_with_raster/georeferencer.rst b/docs/user_manual/working_with_raster/georeferencer.rst index a3b30c43420..5604ffc29b2 100644 --- a/docs/user_manual/working_with_raster/georeferencer.rst +++ b/docs/user_manual/working_with_raster/georeferencer.rst @@ -34,7 +34,7 @@ you can accurately determine coordinates. +--------------------------------+------------------------------+-------------------------------+----------------------------+ | |saveGCPPointsAs| | Save GCP Points As | |transformSettings| | Transformation settings | +--------------------------------+------------------------------+-------------------------------+----------------------------+ -| |addGCPPoint| | Add Point | |deleteGCPPoint| | Delete Point | +| |addGCPPoint| | Add GCP Point | |deleteGCPPoint| | Delete GCP Point | +--------------------------------+------------------------------+-------------------------------+----------------------------+ | |moveGCPPoint| | Move GCP Point | |pan| | Pan | +--------------------------------+------------------------------+-------------------------------+----------------------------+ @@ -70,7 +70,7 @@ The usual procedure for georeferencing an image involves selecting multiple points on the raster, specifying their coordinates, and choosing a relevant transformation type.
