[Qgis-user] QGIS doesn't start anymore: undefined symbol: pj_ctx_alloc

[Luís de Sousa]

Dear all,

QGis stopped running in my Ubuntu 12.04 64 bits. Launching it from dash
nothing happens, no splash screen, no window, no error messages. Launching
it from the command line I get this:

$ qgis
/usr/bin/qgis.bin: symbol lookup error: /usr/lib/libgdal.so.1: undefined
symbol: pj_ctx_alloc

What is it? Again issues with GDAL? Please help, this is really critical to
me.

Thank you.

Re: [Qgis-user] Where is R in QGIS Sextante

[gene]

R has nothing to do with Sextante which only use it. You must install it (see 
http://hub.qgis.org/issues/6029   )

??? It should. It's also used by qgis server to provide print capabilities.
Anyway, I'll test it with any RT-WMS, ASAP

Re: [Qgis-user] qgis and Large Format Print

[Andrea Peri]

No problema, but
AFAIK the qgis problem don't save the print composer.
so it should always be recreate.

The project is only a layer or two from the RT-WMS.

[Qgis-user] Strange wms behaviour

[Ziegler Stefan]

Hi 

I noticed a strange wms behaviour with one specific wms server. After adding a 
layer from the server the message in the status bar shows "Getting map via 
WMS." But the map won't show up. And the message in the status bar never 
changes. In the QGIS debug messages I found:

Debug: src/core/qgsmessagelog.cpp: 41: (logMessage) 2012-11-14T19:01:48 WMS[0] 
Map request failed [error:Error downloading

The request works in a browser and with wget. Any ideas?

Re: [Qgis-user] qgis and Large Format Print

[Andrea Peri]

Both.
Usually I try to print firstly with 1.8.0.
If it crash , then I try with qgis trunk.
Sometime trunk has successful some other time no.

[Qgis-user] LandScan data

[Luciano La Sala]

Hello QGIS users,

I am trying to work with LandScan data in QGIS V. 1.8.0. to estimate
population at risk in areas of Argentina. I download the sample data file
for Haiti to explore how to import and process the data. 

The LandScan 2011 Global Population Database comes in the following formats:


1. Raster GIS: ESRI Grid format. [Note: the Spatial Analyst extension for
ArcGIS or ArcView (3.x) is required for analyzing the LandScan data.] 
2. HPAC Binary: Hazard Prediction Assessment Capability compressed binary
format. 
3. Binary raster: ESRI binary raster format (see included documentation).
Almost any high level programming language can read this file directly. 
  
This is the kind of data you get after downloading the sample dataset, which
presently includes data for Cyprus, available for download at
http://www.ornl.gov/sci/landscan/landscan_sample.shtml  

This is what a raster LandScan map should look like:
http://www.ornl.gov/sci/landscan/images/Cyprus_Image.png  

However, I could only import grey raster maps of Haiti into QGIS, so far
from what it should look like! Has anyone worked with these type of data
before? If so, any tips on how to proceed? Is there a python plug-in that
replaces LandScan Tools as thay are implemented in ArcMap?

Cheers, 

Luciano La Sala

Re: [Qgis-user] How to compile gdal with ESRI FileGDB

[Eric Goddard]

Below are the steps I use to add File Geodatabase support to gdal. This
worked on Ubuntu 12.04 64-bit, but it doesn't use the deb source packages.
Since you have a 32-bit ubuntu install, you need to download the 32-bit
version of the FileGDB API. I tried to answer your questions as they come
up in the steps I list below, so you may want to read through the whole
thing before starting. Sorry for the length, but I hope it helps!

In terminal:

1. Change directory to wherever you downloaded the FileGDBAPI: *cd
path/to/FileGDBAPI_download*

2. extract the archive:* tar zxvf FileGDB_API_1_2-32.tar.gz* NOTE: Since
you are using 32-bit Ubuntu, you need to download the 32-bit FileGDB API.

3.You need to build the samples to make sure the API works. Change to the
FileGDB_API samples folder: *cd FileGDB_API/samples*

4. type *make*

5. Run a sample to make sure it works. Change directory to the bin folder
inside samples: *cd bin *, and then type *./Querying*. You'll get a bunch
of text in terminal, just make sure it doesn't spit out any errors.

6. If the sample runs successfully, you have a working FileGDB API and you
are ready to compile GDAL. I like to move the FileGDB API to a better
location than the downloads directory, but it is up to you. If you choose
to move it, you can use the paths listed below. If you use your own
location, change the path in the commands below to whatever you used. *sudo
mv /FileGDB_API /usr/local/*

7. Create a LD configuration file so that gdal is able to find the FGDB
libraries: *sudo echo /usr/local/FileGDB_API/lib >
etc/ld.so.conf.d/fgdb.conf *

An explanation of ld is below.

8. run ldconfig to update the linked libraries: *sudo ldconfig*

You're now ready to download and configure gdal.


1. Download gdal from http://download.osgeo.org/gdal/gdal-1.9.2.tar.gz
2. Extract the contents of the gdal archive: *tar zxvf gdal-1.9.2.tar.gz*

3. Change to the gdal directory: *cd gdal-1.9.2*

4. Now gdal needs to be configured. Your configure line may be different
from the one below depending on the options you want included, but the
important line to include is --with-fgdb=/usr/local/FileGDB_API. This is my
configure line on my system: * ./configure --with-geos=yes --with-sqlite3
--with-python --with-spatialite --with-fgdb=/usr/local/FileGDB_API
--with-postgres --with-odbc --with-libkml=yes --with-curl=yes
--with-mrsid=/usr/local/MrSID_SDK/Raster_DSDK
--with-mrsid_lidar=/usr/local/MrSID_SDK/Lidar_DSDK
--with-openjpeg=/usr/include*

The --with statements let the configuration script know what additional
modules you want to be included in the compile. When you install packages,
such as geos, from the repos the libraries are put in paths that ld (which
is a utility that links libraries so that other applications are able to
find them) knows about. When you compile by hand the general practice is to
compile to /usr/local, which sometimes ld doesn't know about by default.
You let ld know about additional paths by creating a configuration file in
/etc/ld.so.conf.d/ that contains the path of your custom compiled
libraries.

To compile GDAL with the options you want, your line might look something
like this:

*./configure --with-geos=yes --with-sqlite3 --with-python --with-spatialite
--with-fgdb=/usr/local/FileGDB_API --with-postgres --with-odbc *

After configure runs, it will give you a summary that indicates what it was
able to find. Check to make sure that there is a 'yes' beside the options
you want. If there is a no beside something you want to include, you may
need to scroll through the output and find the error to see what went wrong.


5. Now you can run make and make install. *sudo make*. When that finishes,
run *sudo make install*.

6. One more step: you need to let ld know about the gdal libraries. Since
we didn't specify a different path, the configure line above puts them in
/usr/local/lib by default. I let ld know about the libraries by adding a
local.conf file to /etc/ld.so.conf.d/. *sudo echo /usr/local/lib >
/etc/ld.so.conf.d/local.conf*

7. Run ldconfig again: *sudo ldconfig*

*
*

You should be able to open geodatabases in QGIS or any other GIS
application that uses GDAL now. I expanded on notes that I took while doing
the install, but I didn't have my linux laptop with me while writing this.
Let me know if anything doesn't work or if clarification is needed.

[Qgis-user] qgis and Large Format Print

[Andrea Peri]

Hi,

When try to plot or export on a pdf an A0 format using the composer.
I see sometime the qgis crash.

I need to print in A0 few times and so when qgis crash, I simply
reduce the quality from 600 dpi to 300 dpi and all go ok.

However I like to understand why qgis crash.
Infact I read somewhere that it is a memory availability problem.

So I like to know if increasing my memory RAM this crash problem could
disappeared.
Also I need to understand if a 4GB ram that is the maximum ram usable
on my window 32 bit.
Could be sufficient for a A0 print.

Thx,

[Qgis-user] save grouped elements in print composer

[Otto Dassau]

Hi,

I created a print composer template and grouped several elements (labels,
figures, ...). If I save the template or create a project file and load/open
it in another session again, the elements are no longer grouped. 

Is it possible to group elements and save the grouped elements and make sure
that they are still grouped for other qgis sessions / templates?

Thanks
Otto
