SMSen mit Linux (… SMS-Server)

Unter Linux können ganz einfach mit einem entsprechenden Modem (zB UMTS-Stick) SMS versendet und empfangen werden. Die Beschreibung nimmt Bezug auf Ubuntu mit Gammu und UMTS-Stick (Huwaei E160):

Die Befehle:

  • gammu-config

  • gammu getallsms

  • gammu sendsms text NUMBER

Im Detail:

Wenn Gammu noch nicht installiert wurde:

# sudo apt-get install gammu

Next, we need to configure Gammu to pickup the correct device. Check your dmesg for the serial port:

$ dmesg|grep tty
[12321.308078] usb 5-3: GSM modem (1-port) converter now attached to ttyUSB0
[12321.308275] usb 5-3: GSM modem (1-port) converter now attached to ttyUSB1

Edit ~/.gammurc, or run gammu-config to change the device settings. Your ~/.gammurc file should look similar to:

port = /dev/ttyUSB0
model =
connection = at19200
synchronizetime = yes
logfile =
logformat = nothing
use_locking =
gammuloc =

Give it a test by getting all the SMS from the device:

# gammu getallsms

This should bring back all the SMS currently stored on the stick, which should include your login details for the Three website (unless you’ve deleted them). To send a SMS use the “sendsms” command:

$ gammu sendsms text 07874454543
Enter message text and press ^D:
Test Message!!!!!1!
Sending SMS 1/1….waiting for network answer..OK, message reference=2

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


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
  • 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:

  • owncloud3
  • 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 !

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.
