This widget allows for the plotting of the Aloha threat zones in Web AppBuilder.
This widget does not model or generate the chemical plume, It only imports the Aloha .pas
file and parses the file to plot the data in Web AppBuilder.
This opens the configuration window for this widget.
A file explorer window opens allowing you to browse to a local image file to use as the widget icon.
Clicking the Aloha Threat Zone widget displays the widget. Clicking one of the browse button will open the file select dialog and allow you to browse to the *.pas file you wish to plot on the map.
Once you have seleted the *.pas file you wish to plot you simply click the draw point button and place a marker on the map identifying the point of origin on the map.
The Results view lists all the threat zone footprints and provides the ability to turn the visibility of the threat zone footprint on and off, as well as the ability to adjust the opacity of all footprints.
