Download/Installation of GRASS-HRU

Downloading the Virtual Appliance and the QGIS-Plugin

The following files should be downloaded from http://www.geoinf.uni-jena.de/~c3schs/grass-hru:

• grass-hru.ova [~550 MB] - contains the virtual machine for VirtualBox, required in the following section
• hruwps.zip - QGIS plug-in

Installing the VirtualBox

The derivation of HRUS with GRASS-GIS, which will be explained below, requires a virtualization software which hosts a linux system and all software and scripts needed. VirtualBox should be used - the current version 4.x can be downloaded at http://www.virtualbox.org/wiki/Downloads. The wizard leads you through the steps of the installation process. It should be noted that:

• a temporary deactivation of the network connection is necessary and therefore not unusual
• all necessary drivers should be installed

After a successful installation VirtualBox can be launched and the import of a preconfigured hard disk image can start:

1. Datei -> Appliance importieren
2. Load the Appliance (see above) under Auswählen (file grass-hru.ova)
   
   
   
3. Apply the imported configuration of the Appliance and end the import process with Abschließen
   
   
   
4. The appliance is being imported...
   
   
   
5. ...and will be available through an entry in the VirtualBox main window (GRASS-HRU 1.0)
   
   
   

Installing QuantumGIS 1.7

The current version of QuantumGIS is available at http://www.qgis.org/wiki/Download. The Standalone Installer is recommended - the download address for version 1.7 is http://www.qgis.org/downloads/QGIS-OSGeo4W-1.7.4-d211b16-Setup.exe.

Please note: For the HRU derivation the GRASS plug-in for QuantumGIS is not required but it is included in the installer version >= 1.6. As an alternative, the installer version 1.4 of QuantumGIS can be used, which does not install a GRASS plug-in and therefore reduces the filesize. (http://qgis.org/downloads/QGIS-1.4.0-1-No-GrassSetup.exe)

Installing the Plug-in

To install the actual plug-in for HRU derivation in QuantumGIS the following steps have to be followed:

1. Unzip the zip archive hruwps.zip, which has been dowloaded (see above), into the plug-in file of QuantumGIS. According to the QuantumGIS version the folder is called
   • ../QuantumGIS/python/plugins or
   • ../QuantumGIS/apps/qgis/python/plugins
2. start QuantumGIS
3. Plugins -> Plugins verwalten
   
   
   
4. Search for HRU WPS-Client in the QGIS Plugin Manager, activate it and confirm with Ok
   
   
   
5. The tool for HRU derivation can be started by using a separate button in the menu bar
