[Qgis-user] Print composer fails on print or export

2016-05-25 Per discussione CARLO CORMIO 
Dear All,

I'm trying to print a couple of maps (with rasters, vectors and bing maps)
in a canvas through QGIS map composer. Setting the composition (adding map,
text, scale, etc) works fine, as always, but when I try to print or export
it in any file format the canvas disappear, no error message pops up, no
hardware runs (no lights blinking on my PC).

Page setup is custom (170 x 100 mm) and the maps reach page border, I don't
know if this could be a problem.

I had the same problem with different QGIS versione (2.12 and 2.14), so
maybe it is a local problem. Any idea? I'm working on Windows 10 64 bit,
and use PDFCreator as pdf printer.

Thanks in advance,

Carlo

[Qgis-user] Very slow getCapabilities with materialized view

2016-05-25 Per discussione Nicolas Boisteault 

QGIS Server 2.8.9; PostgreSQL 9.3.13; PostGIS 2.1.8, PGAdmin 1.22.1

Hi,

I have a project I use with QGIS Server which has about 40 PostGIS 
layers and some of them are queries on a materialized view.


A getCapabilities query timeout after 10 minutes. I looked at postgreSQL 
log and saw that QGIS make this query :


"SELECT st_extent("the_geom") FROM (/myquery/) AS "subQuery_0"

which needs to run completely my slow query to get the extent.

I've used "estimatedmetadata=true" so I think this is not the correct 
behaviour and statistics should be used.


Now when I look statistics for my view in pgadmin, a message says that 
'there is no statistics for the selected object'.

I ran an ANALYSE of my view but that changes nothing.

So I have several questions :
- First, is there a way to tell QGIS Server to use the project extent 
for every layer to avoid st_extent on every queries and speed up 
getCapabilities?
- Are pgSQL statistics available on materialized view? If yes, are 
statistics used by QGIS on view?


Thanks for your help!

Not sure, but I recently had a GDB from somebody which could be opened
in QGIS, but did not show anything.

Upon further investigation by Even R, he found:
"It uses the "GeneralPoint" type instead of the regular Point."
And fixed it \o/
https://trac.osgeo.org/gdal/ticket/6478

Moral of all this:
- propriatry format tend to 'change' easily when the owner of the format
needs something (or just wants to release a newer version): prefer
(real) open file formats when you get/exchange data: gdb is smelly

- if something seems wrong: try to create a small subset of the data,
and create an issue for it with gdal or qgis and attache this test data!

- also check with latest gdal/ogr version, because as you see above it
is possible that it is already fixed, just not yet available in released
lib-versions (or your software is not yet released with that lib
version)

Regards,

Richard Duivenvoorde

I'm having the same problem using Qgis 2.14.2, and osx with gdal 1.11 and the
filegdb plugin also 1.11 installed form Kyngchaos server, and the esri
libraries installed per the instructions.

Checking OGR via command line I get

MacBook-Pro-2:DCP_Ecosystems knussear$ ogrinfo DCP_Ecosystems.gdb
INFO: Open of `DCP_Ecosystems.gdb'
  using driver `FileGDB' successful.
MacBook-Pro-2:DCP_Ecosystems knussear$ 

and opening in qgis gives me a red bar invalid source error using either the
open GDB or fileGDB choice. Anyone have any advice on how to solve this?

Thanks

Re: [Qgis-user] GEOS projection adding graticules produce some error

2016-05-25 Per discussione Nicolas Cadieux 
Hi, 
I don't use that projection but make sure the file and the project are saved in 
the same projection. Sometimes, reprojection on the fly does that. You 
can also try creating a spatial index. 
Hope this helps

Re: [Qgis-user] Is QGIS showing the records with geometry NULL

2016-05-25 Per discussione Nicolas Cadieux 
Hi, 
Is it possible that the 2 missing records were deleted in another GIS? There is 
an issue with deleting records in shape file as there are many ways to do 
that. If the record were deleted in another GIS, they may show up (or 
not) in another software. Could that be it...
