THREDDS Explorer is a QGIS-based plug-in designed to make it easy for users to access georeferenced data accessible through any THREDDS based server.
Data catalogues and maps are exposed to the user through a simple user interface, which allows him to choose any map or explore all contents of the server without resorting to exploring the default web based THREDDS interface.
This plug-in should work with most THREDDS servers, and will be able to retrieve any layer provided through WMS, WMS-T and/or WCS services published by the server.
Dependencies: THREDDSExplorer requires the processing plug-in by V. Olaya, available within the standard QGIS Installation (also at https://plugins.qgis.org/plugins/processing/).
Installing the plug-in basically involves copying the code in a QGIS "plugins" directory, as detailed below.
Please note that it is mandatory that the folder where the code resides is called "THREDDSExplorer". If you download the code in ZIP format the default name ("THREDDSExplorer-master") must be changed to "THREDDSExplorer".
The folder where the code should be copied is the following, substituting "%USERNAME%" with your user name:
C:\Documents and Settings\%USERNAME%\.qgis2\python\plugins
If you want to install the plug-in for all the users in the system, you should use the following folder instead:
C:\Program Files\QGIS\python\plugins
This procedure works on Linux Mint 17.3, with QGIS 2.14 Essen. If you want to download the latest version of the code via git, and make it available for a single user:
$ mkdir ~/.qgis2/python/plugins
$ cd ~/.qgis2/python/plugins/
$ git clone https://github.com/IHCantabria/THREDDSExplorer.git
If you want to download a ZIP, you can also do so:
$ mkdir ~/.qgis2/python/plugins
$ cd ~/.qgis2/python/plugins/
$ wget https://github.com/IHCantabria/THREDDSExplorer/archive/master.zip
$ unzip master.zip
$ mv THREDDSExplorer-master THREDDSExplorer
$ rm master.zip
If you want to install the plug-in system-wide (for all the users), you can substitute the directory in the examples above with /share/qgis/python/plugins/. In that case, you will have to use sudo or be root to mkdir the plugins folder, and download content to it.
Installation on OS X has not been tested. Instead, the instructions at qgis.org have been followed (http://docs.qgis.org/1.8/en/docs/user_manual/plugins/plugins.html):
/Contents/MacOS/share/qgis/python/plugins
/Users/$USERNAME/.qgis/python/plugins
NOTES
- It is possible to define additional paths for QGIS to look for your plug-ins, by defining the
_QGIS_PLUGINPATH_environment variable with a full path to the new desired plug-in folder.
For more information you can find a PDF manual under the "doc" folder.
