Customized settings

I think the version of dump shows on the GUI.

The easiest way to get the dev version is to use Joe’s Scripts.
ads-b-flight-tracking-f21/ads-b-receiver-project-setup-scripts-t36532.html
It takes 4 commands, answering a few questions and a reboot.
The scripts allow you to feed multiple sites, adds stats graphs an you can even add heywhatsthat.com range polygons.
The table on the RHS gets range and flag(nation of registration) columns
You get your choice of maps: road, terminal, IFR and world etc.
There are links to see the FA info on the flight or the airframes.org data on the transponder hex code(ie who owns it).
Correctly identified helicopters show up as helicopter icons.
They recently added a larger aircraft icon for heavy aircraft(emitter cat 5 = Heavy > 300 000lbs I believe)

You can set range circles in /usr/share/dump1090-mutability/html/config.js

SiteCircles = true; // true to show circles (only shown if the center marker is shown)
// In nautical miles or km (depending settings value ‘Metric’)
SiteCirclesDistances = new Array(100,150,200,225);

another option is to wait until piaware V3 comes out. It is due soon.

This post shows the later versions with the older google and the newer bing road maps
(google will go away due to a recent google policy change)
You can see the different colours of the aircraft(based on altitude). Both images show A/C at different altitudes.
bright green is on the ground.
