h1. Cloud border plugin

The cloud border plugin registers the location of the cloud border as transmitted by paparazzi, when the liquid water content value changes from zero to positive and vice versa. Activating this plugin also enables the display of border points in the GUI.

h2. How to use it

h3. Scenario definition

Add _CloudBorder_ to the _plugins_ list of an aircraft. The plugin does not have any parameter.

Example:

<pre><code class="yaml">

aircrafts:

    200:

        replay: false

        type: 'pprz'

        plugins:

            # Other plugins ...

            - CloudBorder

</code></pre>

h3. Graphical User Interface

Border points appear as yellow dots in the _mapping_ page. The "Cloud border" checkbox controls de display of these points.

h2. How does it work

The plugin code resides in <code class="shell">nephelae_base/nephelae/plugins/CloudBorder.py</code>.

It works by subscribing to the <code class="python">dc_shot</code> messages from ivy. A <code class="python">CloudBorderSample</code> is disseminated each time a <code class="python">dc_shot</code> is received.
