Preinstalled virtual environment with ADAGUC Viewer and ADAGUC Server¶

For the workshop a preinstalled virtual machine is available. This machine has apache-tomcat, postgres, adaguc-services, adaguc-server, adaguc-viewer and apache httpd with php and cgi support installed.

The installation instructions can be found here: Install_Adaguc_on_Ubuntu

The following repositories are used:

https://github.com/KNMI/adaguc-services - Java application for running adaguc-server from tomcat or as a spring boot application
https://github.com/KNMI/adaguc-server - C++ server for serving WMS, WCS and OpenDAP
https://github.com/KNMI/adaguc-viewer - Javascript web client for connecting to WMS
https://github.com/KNMI/adaguc-datasets - Example dataset configurations

Installation of the virtual image¶

The virtual image can be downloaded from http://geoservices.knmi.nl/adagucworkshop/adaguc-xubuntu-2017.ova (8.5 Gb, when unpacked 20 Gb)
Install Oracle Virtualbox with the corresponding extension pack from https://www.virtualbox.org/wiki/Downloads
Start Virtualbox, click File -> Import appliance. In the settings, set the memory as high as possible, by default it is set to 2048Mb, but 4096Mb is recommended.
In the VM, just start firefox and the adaguc-viewer will show as default page
From the viewer, the AutoWMS plugin can be opened via clicking on the big gear and selecting AutoWMS from the list. A window on the right opens, displaying all files and folders available.

The VM exposes port 80 and 8080 to localhost, which means that links should work outside of the VM on the host as well.
Use the password "adaguc" to obtain sudo rights

Adaguc viewer¶

The viewer is located at:
http://localhost:8080/adaguc-viewer/

The AutoWMS plugin can be opened via clicking on the big gear and selecting AutoWMS from the list. A window on the right opens, displaying all files and folders available.

Example NetCDF files¶

To update example NetCDF files, please run:

cd /data/adaguc-autowms/testsets
./update.sh

This will load new files from the KDC. (https://data.knmi.nl)

Links to dataset configuration examples:¶

These example configuration datasets are hosted at https://github.com/KNMI/adaguc-datasets
They can be linked into the service by doing: http://localhost:8080/adaguc-services/adagucserver?dataset=<dataset name>
See Dataset for details on how ADAGUC datasets work.
adaguc-datasets can be updated from github by doing:
- ```
cd /data/adaguc-datasets/
git pull
```

Viewer examples¶

The viewer has several examples located at http://localhost/adaguc-viewer/examples/

To see current radar images, go to:

Opendap Server¶

Besides being an OpenDAP client, adaguc-server has the capability to serve OpenDAP by itself. It can serve a set of files and concatenate those virtually over dimensions, e.g. aggregations are possible. To demonstrate this go to:

http://localhost/cgi-bin/adaguc-datasets.cgi/opendap/opendapdataset/RADNL_OPER_R___25PCPRR_L3_KNMI.nc.das

To view an OpenDAP URL with ncview, do:

ncview http://localhost/cgi-bin/adaguc-datasets.cgi/opendap/opendapdataset/RADNL_OPER_R___25PCPRR_L3_KNMI.nc

To view an OpenDAP URL with adaguc-server, do

http://localhost:8080/adaguc-services/adagucserver?source=http://localhost/cgi-bin/adaguc-datasets.cgi/opendap/opendapdataset/RADNL_OPER_R___25PCPRR_L3_KNMI.nc&service=wms&request=getcapabilities

In the viewer:
