[Qgis-user] processing and temporary files on osgeo4w

2017-03-05 Thread Jan Michálek
Hello
I have problem with my batch. I need create topographic wetness index over
really big tiff. I prepared some grid and created in graphical modeler
batch to clip piece of raster by square vector, add some buffer, create
topographic wetness index and clip output by original square. I have some
simple python loop over all features in generated grid and save data. My
problem is in temporary files created by processing, because they are
really big. I tried delete id from python after every iteration of my
script, but files looks be in use (they aren`t). Is some way to remove
temporary files from qgis?

Thanks Je;

[Qgis-user] Problem with GDAL / clip raster by mask layer in processing

2017-02-03 Thread Jan Michálek
Hi
I have this problem.
When I`m using graphical modeler and clip raster by mask layer
in gdal batch is "None" after name of layer (or after BBox coords).

gdalwarp -ot Float32 -q -of GTiff -dstnodata - -tr 5.0 -5.0 -tap
-cutline
C:\Users\BRMICH~1\AppData\Local\Temp\processingb8336a047ad948baa3e04a741135330d\3938c93cc94d4b4bad111c352385f116\OUTPUT.shp

Batch is generated by module. I mean, that this "None" is placehloder for
CRS.
I Use Qgis 2.14 installed on win with osgeo4w. Is there way, how i can edit
my model to get this out? Because with this option gdal batch fall.

Thank Je;

Re: [Qgis-user] Storing data to postgis from Qgis

2014-12-30 Thread Jan Michálek
In db manager you can import data in new table or add features to an
existing table.
Or you can add empty column to a table, select in qgis desktop, open
atribute table, display selected features on top and edit empty column by
your atributes.

2014-12-30 6:10 GMT+01:00 David Kramer dav...@gmail.com:

 Leknin,

 Thanks for the reply. I've followed your recipe and indeed I can paste my
 selected features as a new memory layer (thanks Jan) and then import the
 layer via db manager into postgis. This is tremendously useful, but is not
 quite what I'm looking for.

 I don't really want to create a new table, I really want to just select a
 few fields out of my newly selected layer and save those as a row in an
 already created table. For example, let's assume I have a table that lists
 franchises the states that they do business in and the columns:

 'Franchise Name'|  'States' | 'geom'
 ===
 Alice's Restaurant   | NY, NJ, PA|   ...
 Joe's Burgers  |  CA, NV, OR  |   ...

 To add a new row to the table I'd like to go into qgis, select the states
 for a franchise (from a layer of states), save that as a memory layer. Then
 I'd like to have a save function which allows me to enter the franchise
 name. It would save only the name, the states and the geometry as a row in
 the table.

 Make sense? Is this possible from the GUI or do I need to write a plugin
 in pyQGIS?

 Thx
 David

  On second thought - screenshot overshot the limit for the listserv.

 no - it wasn't really erroring out - just refusing to cooperate. I hope
 this screenshot Attaches properly.

 It categorizes properly in the Layer Properties. Lets try this -
 https://www.dropbox.com/s/kz11etd72o6c4mx/category.bmp?dl=0

 The field called spacing is attributed properly. If I turn off the teal
 point all of them go off.

 It all seems to hinge on varchar vs char.

 I checked the error log and it's clean. Nothing out of the ordinary.

 I'm on Ubuntu 14.04 QGIS 2.6,  POSTGIS=2.1.3 r12547,  and PostgreSQL 9.3.5

  This might be something I should know. I have a point layer in

 I tried to symbolize the point layer on the spacing attribute - it wouldn't.
 I made another field in postgis and called it spacing1 and made it varchar
 and it was no problem at all. Will QGIS not catergorically symbolize on a
 char field in postgis? Not a big deal as I can work around it - just curious
 though.

[Qgis-user] Qgis server returns map from another project, that is defined in URL

2014-07-24 Thread Jan Michálek
Have a nice day
I have problem with qgis server (2.2). I have a few projects in my folders
and qgis doesn't use project specify in my url.

For example i had folder called
projects
with two files. red.qgs a green.qgs with the same layer (from postgis), but
with differenet symbology (fill color).

i use for first time url like this
http://nejakejservr.cz/cgi-bin/qgis_mapserv.fcgi?MAP=/mnt/data/projects/red.qgsREQUEST=GetMapBBOX=-615170.147011,-1003827.798116,-614613.882202,-1003027.916641CRS=EPSG:5514WIDTH=400HEIGHT=300LAYERS=testSTYLES=,,FORMAT=image/pngDPI=96

And I obtain red filled polygons (as is specified in red.qgs project).

If i use this.

http://nejakejservr.cz/cgi-bin/qgis_mapserv.fcgi?MAP=/mnt/data/projects/green.qgsREQUEST=GetMapBBOX=-615170.147011,-1003827.798116,-614613.882202,-1003027.916641CRS=EPSG:5514WIDTH=400HEIGHT=300LAYERS=testSTYLES=,,FORMAT=image/pngDPI=96

I should obtain layer from green.qgs project, but i obtain red filled
polygons from project i had use before.

I had use qgis (2.4) on my desktop for this wms, but with the same problem.
I get lazers from first used project.

Why?

How I can change this?

You must compile gdal with OGDI library, replace your gdal in qgis with
this new gdal.

 Hello,

 I'm new to QGIS.  I was hoping that someone can answer a very basic
 question for me.

 Can QGIS display Digital Nautical Chart (DNC) data in Vector Product
 Format (VPF) from the National Geospatial Intelligence Agency of the United
 States government?  Here's a web page describing these DNCs.


 https://www1.nga.mil/ProductsServices/NauticalHydrographicBathymetricProduct/Pages/DigitalNauticalChart.aspx

 The Supported Data Formats page under the User Manual section of the QGIS
 website provides the following link:

 http://www.gdal.org/ogr/ogr_formats.html

 This page says that the OGDI libray, which is necessary for VPF data, is
 not compiled into the OGR library by default.

 This is why I'm asking the question.

 Thank You in advance,

 Mark

Re: [Qgis-user] Problems with svg symbols on qgis server

2013-12-09 Thread Jan Michálek
We have it on the Gentoo (I`m not sure, but i think, that we have newest
version - 2), i tried all logical posibilities of placing svg files,
absolute path in qgs file etc. With the svg files placed in
/usr/share/qgis/svg, just like on my arch linux desktop it doesn`t work.
Maybe it is rules issue (im not admin of this server), but xserver didn`t
run on our server with high probability, it is only web server.

This script I found in old mailing lists.

Server didn`t crash, my polygons are returned without fill.

I will ask our admin to run xserver and will see.

Thanks Je;

 Hi,

 On what operating system are you and what version are you using?

 It seems to be a path-issue and not an X-Server issue. If it was an
 X-Server issue your QGIS server would just crash - but it looks like
 your maps are drawn, but without SVG symbols. Did you try to copy the
 SVG symbols to a path where the standard SVG symbols are located? E.g.
 /usr/local/share/qgis/svg on Linux?

 Regarding XServer: I use the package vnc4server on my Ubuntu Server
 along with a small start-script I got from Jürgen. Let me know if you
 need this.

  Good evening
  I have a problem with using svg polygon fill on qgis server. My polygons
  aren`t filled. I tried absolute path (in my desktop solution I`m
  changing svg symbol using table variable). Relative path to qgis project
  location and original qgis svg location. Nothing isn`t working for me. I
  found in older posts on this list, i need running xserver on server with
  qgis server (so much servers :D), but it is old post and I don`t know,
  if I actually need this on this new version.
  Our server works on gentoo.
 
  Thanks Je;
