= Clients =

rasdaman can interface with a large and increasing number of tools. Some clients allow direct query submission, such as rasql and directql. For rapid development of browser clients the raswct toolkit is provided.

Geo tools supported include !OpenLayers, QGIS, ncWMS, THREDDS, GDAL, !MapServer, !ArcGIS; soon: !GeoServer.
Geo standards supported are OGC WMS, WCS, WCPS, and WPS; hence, all clients conforming to these standards can additionally be used for interfacing. All geo semantics is implemented through the petascope component ([http://rasdaman.org/browser/applications/petascope source]) which is implemented as a Java application layer offering OGC Web services.


== rasdaman clients ==

 * '''rasql''' is a command-line utility for sending queries and saving results in local files. It is part of the rasdaman package.
 * '''raswct''' is the rasdaman Web Client Toolkit which allows, by way of input and output widgets, to easily compose a Web client. Simple versions need only HTML, but advanced interfaces can be created. One example for the use of raswct is [http://standards.rasdaman.org standards.rasdaman.org].
 * '''rview''' is a deprecated visual query interface for desktop use (executable). It is still part of the rasdaman package, but not maintained any longer. [executable: ]
 * '''directql''' is not strictly a client, but a rasdaman server linked directly with the rasql utility (see above). This simplifies debugging for developers. ([http://rasdaman.org/browser/applications/directql source] )

== WCS clients ==

 * WCS Web client: a generic Web client which allows for convenient forms-based input of WCS parameters for WCS Core and Extensions; all WCS extensions are supported, but the client presents only those extensions which are supported by the server addressed. Results can be displayed graphically where feasible. ([http://rasdaman.org/browser/applications/wcs-client source] )
 * mobile clients (contributed by [http://www.consorzio-cometa.it/ COMETA]):

== QGIS ==

This plugin enables the direct download, processing, integration and usage of Coverages from an OGC compliant WCPS 1.0 enabled servers within the QGIS software (v2.0+ supported). The plugin has been submitted to the official QGIS plugin repository, approval is pending; in the meantime it can be installed manually:

- get the rasdaman source tree:
{{{
git clone git://rasdaman.org/rasdaman.git
}}}
- the plugin can be found in directory `rasdaman/applications/qgis-wcps`
- copy the `qgis-wcps/QgsWcpsClient1` directory to your `qgis-python-plugin directory`, usually located in `$HOME/.qgis2/python/plugins`: 
{{{
$ mkdir -p $HOME/.qgis2/python/plugins/
$ cp -r rasdaman/applications/qgis-wcps/QgsWcpsClient1 $HOME/.qgis2/python/plugins/
}}}
- now you can start QGIS and access the `QgsWcpsClient1` plug-in via the `Qgis Menu → Plugins → WcpsClient1 → WCPS 1.0 Client`

== rview ==
rview is a desktop visualization client component of rasdaman, that communicates with rasdaman via RPC, so rpcbind/portmapper should be installed and running in order to use rview.

The rpcbind service has to be started in insecure mode, or rasdaman has to be started as root, in order for rview to be able to connect to rasdaman.

To start rpcbind in insecure mode:
{{{
#!sh
# note that the service script location may vary among different Linux distributions
editor /etc/init.d/rpcbind

# or in recent Ubuntu's
editor /etc/init/portmap.conf

# then add '-i' to the OPTIONS variable
}}}

After the rpcbind is restarted, restart rasdaman and then rview can be opened with
{{{
cd $RMANHOME/bin
./rview
}}}

'''Important note:''' Rview is deprecated and unmaintained. For building clients use [http://rasdaman.org/wiki/Clients one of the Web client or the raswct library] instead. In fact, there are strong reasons not to use rview: As highlighted using the RPC communication protocol is highly insecure and not recommended. Further, RPC communication is deprecated and will soon be replaced (together with HTTP and RNP) by a new, faster protocol.
