Projection settings (CRS) in QGIS 2.0 Dufour (e.g. Austria)
In QGIS 2.0 Dufour CRS-Settings are “hidden” in a new menu (not anymore in “Settings” like in 1.8).
- Menu “Project” – “Project properties”
- You’ll find an entry “CRS” ! Now you can choose your dedicated CRS and activate “on-the-fly” transformation. Using “on-the-fly” be aware of the correct transformation parameters for your CRS.
- The parameters for Austria (see Screenshot) are OK and there is no difference between using ArcGIS 10.x and QGIS 2.0
Thinkpad x121 disable touchpad ((K)Ubuntu 13.04)
For Trackpoint-Users sometimes the touchpad can be quite annoying. So it can be useful to disable it (an just the trackpoint works). Solution for Linux (Kubuntu 13.04):

- Diable it: “xinput set-prop ID ‘Device Enabled’ 0”
Installation von OwnCloud 5 auf domainGo Webspace (Power)
- Voraussetzung: Webspace mit PHP und MySQL (Optional: SQLite) – zB Domaingo Power-Pakete
- Download des WebInstall-Scripts von http://owncloud.org/install/
- Kopieren des Scripts auf den Webspace – ACHTUNG: Vor dem Ausführen (http://URL/setup-owncloud.php) muss bei Domaingo auf die ZIP-Library in einem php.ini verwiesen werden (sonst bricht die Installation ab).
- php.ini mit dem folgende Inhalt (ersten beiden Zeilen) in den Webspace zum setup-owncloud.php kopieren:
Diese beiden Files sind dann am Webspace:
- Anschließend das Script ausführen: http://yourURL/setup-owncloud.php
- Nun kann ein User und die Datenbank angelegt werden (SQLite!)
- Nach der Grundinstallation empfiehlt es sich die php.ini ins Installationsverzeichnis am Webserver zu kopieren und um die Zeilen im Screenshot zu ergänzen. Achtung: Die upload_size je nach Konfiguration des Webservers einstellen (–> phpinfo() )
From Google Tracks (Android Smartphone) to QGIS
The app GoogleTracks for Android-Smartphones is an easy to use tool for logging GPS-Tracks with your phone – & it allows you to export the Tracks to GPS and KML. So it’s no problem to get your tracks in your GIS-Software.
How-To with QGIS 1.8
- Export your Track to GPX in GoogleTracks on your phone
- Copy the *.gpx on your computer (or by the way mail it from your phone 🙂 )
- You can directly open the GPX in QGIS with “Add vector”
- Attention: GPS-Data is saved in GCS WGS84 ! If you combine it with layers in your national CRS be aware of using the correct transformation-parameters !

Define Austria M31 in QGIS 1.8
In QGIS it is possible (and it’s recommended) to define the project’s CRS (coordinate system).
For Austria MGI M31 use EPSG Code 31258. See screenshots attached.
On-the-fly CRS-Transformation in QGIS 1.8
Quantum GIS has the option to perform on-the-fly transformation between geodata with different coordinate systems within the data-frame.
When to use it ?
You have geodata referenced in different CRS (Coordinate reference systems) in one project (data frame).
Be aware !
Be aware that every data-layer has a coorect CRS defined and the CRS of the data-frame has to be defined !
Also keep attention whether the correct transformation (parameters!) ist performed.
ArcMap: Fighting with Date/Time Fields
Convert date-field (as String) to Date (as Date field) – Update ArcGIS 10
Datefield = format ([date_string_field], "dd-mm-yyyy")
Convert date-field (as date) to string (ArcGIS 10)
DatePart ( "yyyy", [UTC_DATE] ) & "-" & DatePart ( "m", [UTC_DATE] ) & "-" & DatePart ( "d", [UTC_DATE] ) = yyyy-m-d
