It might be more convenient to do an affine transformation, deducting
3200 (32 million) from the easting of each vertex in the shapefile. The
QGIS Vector Affine plug-in can do this.

[Qgis-user] How to Compile GDAL from gdal trunk and qgis from source ?

[laurent celati]

Hello,

I have posted a message there a few weeks. I asked you a way to compile the
"last Gdal version from trunk" and Qgis from source targeting your gdal
source as library in order to use the last Gdal postis raster driver. You
answered that the last binairies qgis 1.8 version is available with the last
version of gdal (1.9.1) and that it's useless to compile.

I understand your reply. BUT I have talked last days with developpers of
"Gdal Postgis raster driver". They just add several important updates to the
driver. And they confirm to me that the only way to use the last driver is
to compile GDAL from gdal trunk and qgis from source using that compilation
as GDAL version.
Please to read below few sentences written by those developpers :
--
That's the only way to get the development version working. You have to
compile GDAL from svn and qgis from source using that compilation as GDAL
version.
I'm not following osgeo4w binaries, but I don't think they would
provide a QGIS build with both gdal and qgis from svn. It's not entirely
impossible because I know they release a few nightly snapshots.
So, you have to use the last GDAL version from trunk in order to have the
last "Gdal Postgis raster driver updates".You just need to compile QGIS from
source targeting your GDAL source as library.I think that if you make any
header changes you may need to recompile it all since QGIS depends on
GDAL.So you have to work with last gdal version from trunk.
--

I need this last version of Gdal Postgis raster driver on my windows 7-64
bits station but those developpers working on Linux.
Could you explain to me the way to compile GDAL from gdal trunk and qgis
from source using that compilation as GDAL version (sources links to
download, compilation procédure,etc.). I am a thematician geograph and i am
a novice in software compilation;-(

In advance, thank you for your reply.

Kind regards.

Laurent Celati

Re: [Qgis-user] Trouble with overlay in 1.8.0

[Roxette]

I am having a similar problem having upgraded from 1.7.4 to 1.8 -
specifically, using fTools to do an intersection between two point datasets
(where the points in each dataset are exactly co-located) creates an empty
shapefile with all the attributes of the two datasets, but no entries. The
SEXTANTE tools, however, seem to work fine?

I have tried the operations on both Mac OSX 10.6.8 and Scientific Linux 6.2
and both are giving exactly the same error for the same data.

Cheers,
Roxette

Right now, the one way for get it working is by apply the patch here [1] or
installing master version!
If issue occurs with dataset which are different from point geometry type,
then it is a bug! If so, please reporting it here [2]

 Hi Brian,
 I downloaded the sample data and imported to my database and it seems to
 work pretty well. I'm using QGIS 1.8, postgis 2.0, postgres 9.1.5, gdal
 1.9.1 on ubuntu 12.04.

 Sorry for my ignorance but what GDAL version is being released with
 linux mint? I couldn't find anywhere online.

 The plugin heavily relies on GDAL to perform the visualization so you
 need the latest GDAL available to get a decent performance.

 From my first tests I can say that GDAL 1.9.1 has greatly improved
 performance and the next versions should improve even further. The fastest
 visualization that I have achieved with version 1.9.1 is with single tiled
 raster files. Unfortunately I wasn't able to get GDAL to use overviews so
 far, but Jorge (GDAL's postgis raster developper) is researching on this
 subject.

 GDAL versions bellow 1.9 should not be able to read postgis 2.0.

 Unfortunately, since postgis 2.0 release, the python loader was
 discontinued in postgis source. Recently I have started to make the
 necessary changes starting from the old code to get it to work. I don't 
 know
 if this is going to be a good solution but it seems possible. I'm trying to
 avoid the platform-dependent compilation that postgis' raster loader has in
 version 2.0 now that it's being entirely written in C. In the future I
 should probably release a simple uploader with the plugin, without all 
 those
 options until I'm certain that everything is working according to the
 standard.

 I'm copying this mail to the list to allow other users to find this
 thread later.

Re: [Qgis-user] Ftools and MMqgis behave differently

[Gerardo Jimenez]

Hi Nick! Thanks for your time in this.
I do the following
1.  I load   poitsccl shape file. CRS is Lambert conformal conic for México. Q 
gis recognizes it as a custom CRS. I enable on the fly crs transformation2. I 
load MMqgis and Mqgis2 shape files. These are the ones created with MMqgis. 
Both are latlon with grs80 datum (Itry to play with INEGI's rules, ITRF CRS)3. 
I load Testgrid and testgrid2 shapes. These are the ones created with ftools. 
Both are latlon with grs 80 datum
I notice that the ones created with ftools are straight lines on the limits 
that you define not the interval ones. This is to say, for instance,  if you 
want to make a grid with 2 degrees of longitude and 1 of latitutude as the 
limits with intervals each 15 minutes, Ftools creates meridians of 2 degrees 
separated by 15 miutes each one. Paralels the same. 
MMqgis does create segments of 15 minutes and finishes them at the limits you 
define. I notice this, if, for instance, you densify the lines with a 100 new 
nodes, the ftools layers will crate 100 new nodes only. In the layers created 
with mmqgis, densify will create  100 nodes each 15 minutes.  This is why I 
think it is better to use the mmqgis grids.
I think the way f tools creates the features makes all the diference.

Thanks for your time Nick!

Re: [Qgis-user] Trouble with overlay in 1.8.0

[Roxette]

I'm having trouble applying the patch because I can't find the Ftools plugin
files anywhere? They aren't in the .qgis/python/plugins directory with all
the other plugins - is this because it now comes packaged with QGIS now
rather than being installed individually? I've done a search and it doesn't
seem to exist - either on my Linux installation or the Mac version.

Any help much appreciated, I'm a newbie to this 



please can you indicate a help resource where it is explained how to apply a
patch to qgis 1.8?
thank you

A way simple to apply the patch is:

1) open the file ftools_utils.py with your text editor
(/python/plugins/fTools/tools/) ;

2) looks at the function "def getGeomType(gT)" and change it as follows

def getGeomType(gT):
  if gT == 3 or gT == 6:
gTypeListPoly = [ QGis.WKBPolygon, QGis.WKBMultiPolygon ]
return gTypeListPoly
  elif gT == 2 or gT == 5:
gTypeListLine = [ QGis.WKBLineString, QGis.WKBMultiLineString ]
return gTypeListLine
  elif gT == 1 or gT == 4:
gTypeListPoint = [ QGis.WKBPoint, QGis.WKBMultiPoint ]
return gTypeListPoint

3) restarting qgis


Hope this helps!

Regards,

-SL

[Qgis-user] null values and color table from grass rasters

[Patrick Giraudoux]

Hi,

I am working with QGIS 1.8.0 lisboa, and have imported a raster into 
GRASS 6.4.2 via the QGIS interface (it was a  TIF file originally).


To my surprise null values are not displayed "transparent" in QGIS but 
at the equivalent of zero in the coloramp.  However, I have checked that 
the values of the cells are really "null" when pointed on with the 
appropriate tool.


When displayed within GRASS (tcltk interface) everything is OK and null 
is transparent.


Any idea about what happens?

Patrick

Re: [Qgis-user] Fwd: wktraster with Postgis 2.0 in QGIS 1.9 on Linux Mint Maya

[Etienne Tourigny]

Brian - no this is not my job, like many people around here.

Sorry I can't help you for the postgis error - hoefully someone else
can step in.
However, I wonder if using another repository (sharpie) for postgis
could be the cause?
Although I assume you need that to get latest postgis. Ubuntugis ships
with 1.5.3-3~precise1

Sadly, sometime to have cutting-edge software you need to compile the
whole stack (or at least qgis) yourself...

Re: [Qgis-user] Trouble with overlay in 1.8.0

[Agustin Lobo]

Would not be better having a version of FTools as a python plugin until all
problems are solved?  This would make the handling of patches much
easier for users.
Note that errors like this are critical for users.

Yep, true - if your 'Temp.shp' is not a DIRECTORY within your documents 
folder.


What you and I call "shapefiles" is actually a group of 3 or more files 
that are needed by ESRI and other GIS products that use 'shapefile format'


For this reason you must specify the name of an existing directory, and 
not a filename that you want to create.


Are you sure the "other paths" you tried existed and were actually 
directory names?


HTH,
Zoltan
