I'm a little out of my league here, I'm not a developer, but was pointed here
from the QGIS-user list.
My question is: Does any coordinate or location data get embedded in the image
file if I use Project > Save as Image or Composer > Export as Image/PDF/SVG
(other than what is literally seen in the image)?
My question is primarily for 2.14.3 now, but later will have the same concern
for the 3.x series when we upgrade.
(I know about the option to check "World file on" and create a separate world
file. What I need is to make sure there is no identifying info whatsoever from
the project file in the image file itself.)
Eg, say I have a basemap like OpenStreetMap open for a country and I load
points in another layer that are inside that country. Then I zoom in on a group
of points from my data layer, I turn off the basemap layer, and make a map with
just my data points. I want to preserve the relative spatial relationships
between my points but not reveal where in the world the map came from. If I
publish this image file, might the metadata or anything else embedded in the
file reveal the location?
So far, the QGIS-user members who've responded and I have found no indications
that this type of data is included, but I'm posting here in case anyone who is
familiar with that code could confirm that. Sorry I'm not able to read the code
myself.
For the work we do, it's critically important we don't unknowingly publish
specific locations. For now I'm taking screenshots to be sure nothing is
transmitted, but that's a limiting workaround.
Thank you, as I said in my first post to the QGIS-user list, I very much
appreciate QGIS and its community!
