[Qgis-user] Change Field Type

I have imported numeric data and some fields have come in as "double - REAL" but others have come in as "qlonglong - Integer64". Is there any way of modifying the field type for a shape file as I want them all as "double - REAL"? Or is there some formatting required of the numbers before you

[Qgis-user] Processing Toolbox

I am trying to run the QGIS algorithms in the Processing Toolbox. What I am trying to do is plot univariate data using the Graphics options, bar plot, mean and stdev, histogram plots etc. When I try to run these algorithms, QGIS crashes. Anyone have any suggestions? I am trying to process

Some more revisions. That's how it looks with straight gradients. No notice-able change, but way cleaner code: https://gist.github.com/tobwen/c07fa2458499c180a3e0585e5d70d802 And that's the flat version with straight gradients: https://gist.github.com/tobwen/cd744ea324ff992a27aad7efd958212c

Re: [Qgis-user] QGIS logo material & visual style guide

Hi Anita, I've just created a fixed logo with generic SVG code. I've tested it in the common browsers, Photoshop, Illustrator, CorelDraw (trial) and Inkscape. It works for me, also the W3-validator and my printers like it. Also, I've tried to optimize as good as I can:

Re: [Qgis-user] QGIS logo material & visual style guide

Hi Anita, I just was about to print the new logo on a bag and realized another bug: The SVG provided is NOT the one seen on the PNG picture! The "3D effect" is missing. My 2 cents: Actually, such pseudo 3D logos aren't modern anymore. All of the big corporations (f.e. Microsoft, Google,

Re: [Qgis-user] QGIS 2.18.2 Crashes often on Mac (Yosemite 10.10.5)

Thank you. I can't reliably "reproduce it" other than knowing that when I have certain multiple layers loaded through a connection in my PostgreSQL database, it can happen often when I pan or zoom the map. As somebody else pointed out, after looking at the stack trace information I posted, it

[Qgis-user] Raster calculator produces Nan values

Hi I am using the raster calculator to compute NDVI maps from nanosatellite images. I have one image (one out of many) for which the calculator produces an output image of Nan values. No problems with any of the other images. The original 4-band 16-bit image has values in all channels - the

Re: [Qgis-user] Processing tools stopped working.

Matthias; I managed to fix all the errors but the one for processing of which seems to be tied to the pyQt modules. I uninstalled all those whl's and the python-QT5 but still not having any luck. The errors for QEsg were solved by reinstalling utilis and matplotlib. Tyler On Thu, Mar 30, 2017 at

Re: [Qgis-user] Processing tools stopped working.

Hi Tyler, this is an issue with the plugin (on some systems) and not an issue with your dependencies. Do not install PyQt packages with pip on the system where QGIS is installed. This will install imcompatible binary libraries which is never a good idea. Matthias On 03/30/2017 06:12 PM, Tyler

I am getting Python errors on QGIS Startup for Processing and QEsg, due to classFactory() error. The issue started when I installed; pip install python-Qt5, PyQt4-4.11.4-cp27-cp27m-win32.whl, PyQtdesignerplugins-1.1-py2.py3-none-any.whl, and pyqtgraph-0.10.0-py2.py3-none-any.whl trying to fill the

Hi all, If I refer to the SpatiaLite version in the 'About' window of the 'Help' menu in QGIS 2.14, I get version 4.3.0. But, if I make a connection via pyspatialite and refer to the version via SQL, I get version 4.1.1. In the x64 version of QGIS 2.14 this does not occur. I am having a problem

Buongiorno, la funzione Processing ->Strumenti geometria vettore -> Dissolve permette di eseguirlo in base ad un campo di raggruppamento. Se vedi, nella finestra dello strumento, c'è un "Campo ID univoco". Se deselezioni "Dissolvi tutto" (flag) e selezioni il campo di raggruppamento, il dissolve
