have to re-load as a basemap via the Open Layers menu.

Actually there is a problem with the OpenLayers plugin. For some users 
OpenLayer layers aren't restored when opening a project.

See <https://hub.qgis.org/issues/10766>. I suggested a workaround there, don't 
know if it works for others.

Re: [Qgis-user] GRASS Mask Issue QGIS 2.2

Subject: Re: [Qgis-user] GRASS Mask Issue QGIS 2.2

Hello again:

Perhaps there is an incompatibility between QGIS and GRASS: now QGIS produces 
"-inf" (-infinite) values for null cells, so any operation or function that 
involves al least one those cells, give us -infinite values (constant + - * / 
-infinite = - infinite).

So, as you get -inf values, then scale of values is so large that finally all 
is pink color.

I think that it must be fixed to get "null" values again, as in QGIS 1.8 
version, because GRASS works with "null" values, not with -inf... or What do 
you say, dear developers?.

Hello all:

Thanks to Carlos Cerdan for his advice.  Apparently, QGIS has some issues with 
integer rasters containing nodata values.  When the raster for masking use is 
floating point, QGIS does not paint nodata cells.  On the contrary, when the 
original raster is integer, QGIS fills nodata cells with pink color (which 
makes no sense).  The big problem/question is why even if the mask exists, 
further rasters will not have nodata values outside the AOI.

Then...
Following Carlos' advice, I converted nodata cells to zero using 
r.null.to
Since my purpose is to compute area coverage and percent coverage for risk 
zones inside a municipality:
I multiplied the 1,0 raster layer by the integer risk_index (that is 1to5)

Then I used r.null.val to set zero value cells to nodata because I wanted to 
use r.stats to compute areas and percentages with the option of ignoring nodata 
cells.

Finally (and happily) the r.stats results were more realistic, taking away the 
area outside the "mask".

[Qgis-user] libqgis-dev self-conflict on Ubuntu

[David John Beaton Pearce]

I am trying to install libqgis-dev 2.0.1-2+raring1 on Ubuntu 13.04 64 bit
Synaptics refuses to install, as it conflicts with libqgis-dev ie itself.
There are no other earlier versions installed on this PC
The deb should be coming from http://qgis.org/debian
This has been happening for a few point releases of 2.0.1 on Ubuntu

The same package installs on another PC with very similar setup

David

Re: [Qgis-user] Can't use two base maps

[David John Beaton Pearce]

I can confirm this for QGIS 2.0.1 64bit on Win7.
Actually it says "Could not draw Bing Road because" and then nothing else

In QGIS 2.0.1 x86 under Win XP I can have two OL layers, but cannot make one 
transparent to see the one beneath as "Warning: This layer does not have a 
properties dialog"

Subject: [Qgis-user] Can't use two base maps


Hi,

In QGIS 1.8, I'm able to have two base maps using the OpenLayer plugin. For 
example I could have the Google street map and the satellite map. And I can 
switch from one to the other by selecting and unselect the top most basemap in 
the layer panel.

But I'm not able to do this anymore in 2.0, getting error like: QGIS can not 
draw "..", giving no explanation.

Is this capability removed in 2.0?

Thanks  :-)

[Qgis-user] OpenLayers Plugin layers not saved in 64 bit versions of Qgis 2.0.1

[David John Beaton Pearce]

Resending this with more information after registering onto the Mailing List.
I see this on 2.0.1 64 bit Ubuntu and 64 bit Windows 7 with OpenLayers plugin 
1.1.1

Install OpenLayers plugin
Create a vector layer to give a suitable lat/long based map region
Create a new OpenLayer layer, any will do.
Save As filename.qgs
Close Qgis
Reopen and open filename.qgs
Result OpenLayer layer is not listed or drawn, the first vector layer is drawn

I can see the missing layer listed in the .qgs xml

The same test on the Windows 32 bit version on XP works as expected. Reopening 
the .qgs project lists the layer and it is displayed

Regards
David
