Hi Lene,
Yes - the Google images are quite up-to-date in my region as well.
Definitely a big plus.

Hi Andreas, Nyall and Paolo,
I´m well aware of all these incidents. I just had a urgent need for
getting the newest Ortophoto for a specific area. And Google did have
one from summer 2015. My drone recording went wrong and I had a
deadline. So Google saved my day. The print scale was 1:2000 and was OK.
My drone ortho is normally much better J - 2 cm pixel gives a
brilliant map.
But still the OpenLayer Plugin give me a lot of trouble…. CRS and OTF
crash.

Lene

Hi,
From a technical point of view it seems to work. But as Nyall said,
you are not allowed to use Google tiles directly and print out your
own layers on top of it. For that reason we can't add any Google
layers to QGIS - officially.
I tried it out - for aerial images the reprojection works fine (if one
also uses bilinear/cubic/average interpolation) - but the maps with
lineart and labels look really, really ugly after they had been
reprojected.
If you print out at high resolution - again the aerial images look
fine, but the higher you increase the resolution, the thinner the road
symbology gets and the roads get labeled way too often - so not very
pretty from a (carto)-graphical point of view. I was impressed though
that you can also print at very large sizes (I tested an A0 map wirh
my layers and Google images in the backdrop - it took very long to
render, but it worked). If you use this too often, there is also the
risk that Google blocks your IP address.
The Swiss OSM association offers tiles in the native Swiss projection.
This allows to print much nicer maps than with Google maps. See
http://sosm.ch/swiss-lv95-projected-tiles/ and you can use the
attached xml file to open as a raster image. I think it would be a
good idea if other national OSM associations would offer their data in
the native national coordinate system. Something to discuss with your
local OSM gurus ...
The nice thing about this tile-map GDAL provider is that you can
manipulate the raster on the fly (e.g. convert it to black and white,
make it darker or lighter, change contrast or colors globally, etc.)

Hi,
Just got a small Christmas present from my husband. 6 XML files :-)
Containing Google and Streetview. And then you might say 'Yeah we already
got that in OpenLayer Plugin' - Correct. But when I use OpenLayer, the vector
layers always fly around and calculations mess up.
So now I got the XML files.
Renamed to Zip and Unzipped the files. Open as Raster.
They are now changed in the 'On The Fly' - in any CRS I want.
Now I´m looking forward to my real Christmas Present - Hope Bo read this
mail so he don´t forget ;-)
Regards
Lene Fischer
