Re: [Qgis-user] printing with google layers
Nice! This one works even in the map composer. The main problem is rescaling. There can be a bigger problem, as using gdal can violate a few terms of their license: http://code.google.com/intl/en/apis/maps/terms.html (10.1, 10.8, 10.13? - I've only read it briefly) Seems the OpenLayers plugin is the only legal way, as it's a web browser in fact. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

This works for googlemaps. What is the server url for google imagery?

I can only say what I can see in a web browser, surfing googlemaps. It seems
there is one server for the imagery:
http://khm0.googleapis.com/kh?v=78x=38y=22z=6
(of course x,y,z values has to be replaced with ${parameter}. I don't know
what is v parameter)
and second one for the maps:
http://mt0.googleapis.com/vt?lyrs=m@145x=38y=22z=6
where:
lyrs=m@145 - full map
lyrs=h@145 - map overlay for hybrid
lyrs=t@126 - clean terrain
lyrs=t@126,r@145 - terrain + a label overlay
Again, I don't know what the numbers mean.

There's no simple way (yet) to restrict scale set to meet the tile scales. For display, you just see ugly rescaled image, what can be simply avoided - just do zoom to best scale (1pix=1pix) in the legend mouse menu and then only zoom with mouse wheel or +/- tools to keep always the 2x factor. This way you always fit into tile scale without rescaling. I haven't performed serious pritnting tests, but I expect one more problem: print resolution probably forces downloading tiles for greater or less zoom, as gdal consider TMS as a pyramid. You can try to fix it by setting the zoom level for the pyramid basis in TileLevel xml tag. But I get transparent salt and pepper effect for for very dark pixels. Maybe it's an 8bit - RGB conversion issue? ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
[Qgis-user] printing with google layers
Howard Yamaguchi, In the list of layer on the left of the screen, right click on the raster layer provided by the google plugin. In the properties youve got an option calls pyramids (or something like that sorry for the English ;) ). My advice is to zoom in approximatively at the scale youll print and next use the plugin (to have a good resolution). Youll may have to load many rasters from the plugin.

Re: [Qgis-user] printing with google layers
interesting to hear! So the printing limitation is caused by the Open Layer Plugin and not by the Google WMS(?). I hope new versions of the Open Layer Plugin will address this problem...

There is no Google WMS, they are static tiles. The two plugins make two
different workarounds to use them. OpenLayers Plugin is great for display,
however I expect big problems with proper printing, so wouldn't be
optimistic...
I wonder if it's possible to use GoogleMaps in Qgis directly via GDAL TMS
driver. I'm able to open it, but can't cope with colors: Google serves 8bit
pngs, while Qgis needs RGB. Maybe other gdal versions do it more smoothly?
On the http://www.gdal.org/frmt_wms.html you have a link to the OpenStreetMap
TMS Service Example:
http://www.gdal.org/frmt_wms_openstreetmap_tms.xml
Just download this file and open in Qgis as a raster. You shold see OSM layer
with proper or bad colors ;) In order to use googlemaps instead of OSM,
replace the third line of the file with:

Re: [Qgis-user] printing with google layers
Hi Jonathan, faced the same problem recently, and if I understood right it is a limitation of the Google WMS. I think the capabilities of the WMS description tells you if you can print and what size (if I remember right the parameter is called map extend, but I am not sure .. if this is set to 0, you can´t print anything. A possible workaround is to make a screenshot of the Google layer and open it in the map composer as a background photo (you can use the save image under the File menu in QGIS), another possibility is to reduce the size of your area to be printed, maybe you are allowed to print a smaller part Regards, Markus -- Dr. Markus Weidenbach *landConsult.de* Geographical Information Management and Environmental Planning D-3 Schenkenzell Germany e.mail see: http://landConsult.de Am 07.02.2011 14:37, schrieb jonathan ALLAIN: Hello, I try to print a map with an open layer layer (google satellite).
