[Qgis-user] 0, null values and color table GRASS/QGIS

[Patrick Giraudoux]

Hi,

I am using QGIS 1.7.0 Wroclaw (and GRASS 6.4.1 inside).

I have some troubles with map displays in QGIS with 0 and null values.

I just want to extract a particular habitat category from a Global Land 
Cover 2000 raster into a raster of presence/absence (and NULL value for 
ocean and waterbodies)


This makes the following:

r.mapcalc "V7_01=if(AsiaGLC2000==7,1,0)"

So far so good, I get a raster V7_01 with null values and 1 for pixel of 
category 7, 0 for the others and null values stay NULL. All is correctly 
displayed by QGIS.


Now, I would like to transform V7_01 into a floating point map, and then 
use r. neighbors for a neigborhood analysis.


r.mapcalc "V7=1.0*V7_01"

I get a raster named V7 BUT strangely for any color table, 0 value is 
considered NULL (transparent) when displayed by QGIS. However, the 
original NULL values are well kept and distinct in  this raster (e.g. 
NULL pixels are informed as NULL and 0 pixels are 0, respectively, which 
is correctly displayed within GRASS).


An indication about what happen is that the metadata inform that null 
values(nodata) are -2.14748e+09  in AsiaGLC2000 and V7_01, but become 
2.22507e-308 in V7 (so close to 0).


Any suggestion welcome, I am stuck...

[Qgis-user] Transforming Gauss-Krueger 3 to ETRS 89 UTM32N

[Klaus mithöfer]

Dear all,

I have a problem transforming shape files based on Gauss-Krueger 3 (EPSG 
31467) to ETRS 89 UTM32N (EPSG 25832). The problem is the eastern value. 
It has only 6 instead of 8 digits, the first two numbers are missing in 
ETRS system (e.g. 570873 instead of 32 570873). Could anyone give advice 
on how to do the transformation?


Thank you

Re: [Qgis-user] Transforming Gauss-Krueger 3 to ETRS 89 UTM32N

[Bernhard Ströbl]

Dear Klaus,

the transformation is correct. EPSG:25832 is defined without the leading 
UTM-Zone (32) as the zone is part of the projection's description. At 
least ome German "Bundesländer" however put the 32 into their ETRS89 
data (no ides why, thus there is no EPSG-code you can use for these 
data). You have to create a custom projection with a false easting of 
3200.
Be sure there is a datum transformation performed otherwise your data 
can be some tens of metres wrong or use the Beta2007 grid

Shouldn't the false easting in the custom CRS be 32.500.000 ? The normal 
"false easting"  for UTM is 500.000. The 32.000.000 must be added to 
this value.

[Qgis-user] nadgrids beta2007

[Sylvia Preuß]

Liebe Quantum Gis Benutzer,

 

Ziel ist es, eine csv-Datei mit GK2-Koordinaten (NRW) On The Fly in Quantum
Gis in ETRS89/UTM Zone 32N

zu projizieren. Mit folgenden 2 Beispielen aus vorhanden Koordinatensystemen
reicht die 

Genauigkeit leider nicht aus.

 

a.csv

2591543,00;5654282,00;a



1.

Projekteinstellungen

+proj=utm +zone=32 +ellps=WGS84 +datum=WGS84 +units=m +no_defs

WGS84; 32632

 

Räumliches Bezugssystem des Layers

+proj=tmerc +lat_0=0 +lon_0=6 +k=1 +x_0=250 +y_0=0 +ellps=bessel
+datum=potsdam +units=m 

+no_defs

 

DHDN Gauß-Krüger Zone 2;31466

 

Abweichung ca. 4 m



2.

Projekteinstellungen

Abweichung ca. 150 m

 

Deshalb möchte ich in QGIS ein benutzerdefiniertes Koordinatensystem
erstellen mit nadgrids 

beta2007.gsb

Folgende 2 Varianten habe ich z. B. angelegt.

+proj=tmerc +lat_0=0 +lon_0=6  +k=1 +x_0=250

+y_0=0 +ellps=bessel +datum=potsdam +units=m +no_defs
+nadgrids=C:\Pfad\zu\beta2007.gsb

 

Nachdem ich Textdatei (a.csv) als Layer importieren ausgeführt habe,
Layereigenschaften - 

Allgemein auswähle und unter KBS angeben das benutzerdefinierte
Koordinatensystem auswähle, 

werden die +nadgrids=C:\Pfad\zu\beta2007.gsb nicht mit angezeigt, sondern
die Parameter auf

+proj=tmerc +lat_0=0 +lon_0=6  +k=1 +x_0=250 +y_0=0 +ellps=bessel
+units=m +no_defs 

reduziert. Überschreiben lässt sich diese Zeile nicht. 

In das Feld Initialisierungsfunktion kann ich alles komplett einfügen jedoch
reagiert QGIS nicht 

darauf.

 

Wie kann ich die nadgrids-Funktion On The Fly verwenden? Wie muss das
benutzerdefinierte 

Koordinatensystem aussehen?

[Qgis-user] custom reference system

[Jake Maier]

I try to make a blueprint for a stirling engine that I want to build. I
think I'll need a custom crs for that. How would I go about it. What would
the code look like. Or is it all together a silly idea and I should look for
another drawing program to create blueprints?

Any opinion and or help with this anyone?

Thanks

Hallo Sylvia,

this is an English speaking list
Which version of QGIS are you using?
I can confirm that the +nadgrids... parameter is missing in 1.7.4 if I 
want to apply my custom CRS to a layer on Windows, but it stays in 1.8.0.

[Qgis-user] creating .gpx file strips out al the attributes

[M . E . Dodd]

The 'save as' command in qgis seems to strip out attribute data when creating 
files of certain sorts such as .gpx and also gives problems with .kml where the 
markers are not identified with any of the attributes.  Are there any 
workarounds for these problems?

More detail on the .gpx issue, it will produce a .gpx file if you select 'skip 
attribute creation' but if you don't select this then it fails with the error 
message:
"Export to vector file failed.
Error: creation of field tree_id failed (OGR error: Field of name 'tree_id' is 
not supported in GPX schema. Use GPX_USE_EXTENSIONS creation option to allow 
use of the  element.)"

It appears to be quite a helpful error message except that I can't see anywhere 
to "Use GPX_USE_EXTENSIONS creation option"

Qgis 1.8 or 1.9 on windowsxp

Re: [Qgis-user] nadgrids beta2007

[Harder, Asmus]

Hallo,

I have a custom CRS that looks like
"+proj=tmerc +lat_0=0 +lon_0=9 +k=1 +x_0=350 +y_0=0 +ellps=bessel +units=m 
+no_defs +nadgrids= C:\Pfad\zu\nadgrid.gsb +wktext"
and this works fine (also in 1.7.4), so try the parameter "+wktext" ...
Or have a look at the names of your folders, spaces and german "Umlaute" are 
also often the reasen if something is going wrong.

Re: [Qgis-user] creating .gpx file strips out al the attributes

[Bo Victor Thomsen]

  
  

  Write "GPX_USE_EXTENSIONS=YES" in the "OGR
  creation options", "Data source" section 
  
  like this:

  
  
  Remember to choose EPSG:4326 as the CRS. Thats the only CRS that
  the GPX format formally support

make sure gdaltools plugins is enabled (plugins->Manage Plugins), then
go to Raster->Extraction->clipper. Not sure what the names are in
español though.

Re: [Qgis-user] nadgrids beta2007

[Andre Joost]

Hi,

looking at the CRS below, there is no +towgs84-parameter.

Current Qgis has the following string for EPSG:31466, which is 
Gauss-Krueger-2:


+proj=tmerc +lat_0=0 +lon_0=6 +k=1 +x_0=250 +y_0=0 +ellps=bessel 
+towgs84=582,105,414,1.04,0.35,-3.08,8.3 +units=m +no_defs


This was changed some time ago. Perhaps this is already sufficent for 
your needs.


The +towgs84 values vary across Germany. Thats what beta2007 is for. But 
within one state a constant value should be sufficent in most cases.


You can find other towgs84 parameters here:

Well, just do as you are told:
Insert GPX_USE_EXTENSIONS=yes in the layer field, and the GPX creation 
works.

Unless you want to reproject or share the data with others, I doubt there's 
much reason to define a system.  Cool idea for an experiment either way... err

You can copy the SQL from the layer's metadata.

Hi, thanks for your quick response. The add gdaltools what I have on. In
fact cut a raster if I can, so I can not cut the raster is a mask. That is
asking that the court limit is determined mask. Thanks. Lorena

Hi I'm sorry but I don't understand your question... you mean that it
doesn't work if the raster is a mask?

By the way, there is a Spanish list at osgeo, although not specific to qgis

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

[Mauricio de Paulo]

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.

I'm running Ubuntu Mint 13 Cinnamon with Postgres 1.9.5, Postgis
2.0. and QGIS 1.9.0

I followed this install tutorial:

http://linfiniti.com/2012/05/installing-postgis-2-0-on-ubuntu/

I loaded the sample vector shapefile into my new 'training'
database and opened it in QGIS with no problem.

I loaded the sample raster data using the command in the tutorial,
it loaded with no problems.  I ran the test query in the tutorial,
no problem.  I went into QGIS to load the raster and got an error
that referred to some missing python dependencies (i think it was
the python-psycopg libs)... so I went to Synaptic and loaded the
following:

Installed the following packages:
libjs-sphinxdoc (1.1.3+dfsg-2ubuntu2.1)
libjs-underscore (1.1.6-1ubuntu2)
python-dbg (2.7.3-0ubuntu2)

python3.2 (3.2.3-0ubuntu3)
python3.2-dbg (3.2.3-0ubuntu3)
python3.2-minimal (3.2.3-0ubuntu3)

I then came back to QGIS to open the raster and no longer get the
python error... this time it brings up the "Load PostGIS Raster
Layer" just fine and displays my sample raster.  I click on the
raster name in the table and it puts it down in the "Table Name"
input box.  I then click on OK and get a window that pops up
saying "Could Not Load Layer".  I click ok to this and another
window comes up that says:  "Could not load PG: dbname=training
host=localhost user=postgres password=xx port=5432
schema=public table=srtm_4326 mode=2".  When I click ok to this,
the window diappears and nothing happens.

I also tried one of our ortho geotiffs using the following command
and get the same results:

Linux Mint uses the ubuntu repositories, so look in the main ubuntu

according to this, it uses 1.7.3

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

[Mauricio de Paulo]

Hi, Brian and Etienne.
Well, GDAL 1.7.3 was one of the first efforts to read postgis raster, 
back in the release candidate days. A few months before the release of 
postgis 2.0 there was a major change in the raster storage and some code 
was discontinued. GDAL 1.9.0 was the first release after postgis 2.0 was 
released so it's the first version that is compatible.


Fortunately, vector data is a mature standard inside postgis and didn't 
suffer any major changes that could break previous working code.


Even though we were all notified by these changes, some of our previous 
work doesn't work with the current version. It was a huge improvement in 
raster storage and metadata retrieval, so we have to cope with it.


I'm releasing the new plugin version with the weak loader tonight. It 
should be enough to upload one untiled raster with no overviews to the 
database.


I'm using ubuntugis' repositories. The gdal package available on it is 
version 1.9.1 so you might want to try those binaries, since they work 
pretty well.


All the best,

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.

I'm running Ubuntu Mint 13 Cinnamon with Postgres 1.9.5,
Postgis 2.0. and QGIS 1.9.0

I followed this install tutorial:

http://linfiniti.com/2012/05/installing-postgis-2-0-on-ubuntu/

I loaded the sample vector shapefile into my new 'training'
database and opened it in QGIS with no problem.

I loaded the sample raster data using the command in the
tutorial, it loaded with no problems.  I ran the test query
in the tutorial, no problem.  I went into QGIS to load the
raster and got an error that referred to some missing python

went to Synaptic and loaded the following:

yes, it would be a very very useful feature especially now that google map
