What is the Maximum Range I can Get?

I kind of had the same issue. So I did the following and it seem to fix it.


sudo service lighttpd restart

After that I was able to see the new update with the weather on the Dump1090 map. Using Safari. But I can not get it to work now on Google chrome, I.E and the new Windows 10 browser and Firefox. HMMM… :open_mouth:

142

Thanks, I also use Safari. Let me test with the others and fix.

Edit: Yes, I agree, something is broken in all browsers apart from Safari! :open_mouth: Mea culpa. Stand by…

143

Should now be fixed. Stupid mistake… :confused:

Only file changed is script.js, pull that down and do a hard reset of the browser.

Tested in Safari, Chrome, Opera, and Edge.

Been out a while and return find a lot of new addons!
Thanks Lignumaqua for your addons and for sharing your work.
I have wanted weather radar for a long time!

145

Lignumaqua, you are the man!

Works perfectly apart from lack of weather!


Another sunny January day in Spain!

Many thanks,

Phill

I see what appears to be two range plots. I only have a green one on the addons I loaded. Did I miss something??

Those are terrain limited range predictions provided by the API on heywhatsthat.com. Oliver added support for those. Here’s the instructions:

// Add terrain-limit rings. To enable this:
//
// create a panorama for your receiver location on heywhatsthat.com
//
// note the “view” value from the URL at the top of the panorama
// i.e. the XXXX in heywhatsthat.com/?view=XXXX
//
// fetch a json file from the API for the altitudes you want to see:
//
// wget -O /usr/share/dump1090-mutability/html/upintheair.json
// 'http://www.heywhatsthat.com/api/upintheair.json?id=XXXX&refracti$
//
// NB: altitudes are in meters, you can specify a list of altitudes

You can have as many as you like at different altitudes.

I have one set at 40,000 ft (blue) and one at 10,000 ft (red) . The 40,000 somewhat corresponds with the actual (green). Interesting that I don’t seem to get as far over the gulf as predicted. That could just be lack of high level flights pushing out the actual polygon.

148

These are heywhatsthat theoretical range lines that dump1090-mutability can add semi-automatically. Probably the easiest way is to run the automatic setup scripts: http://discussions.flightaware.com/ads-b-flight-tracking-f21/ads-b-feeder-project-setup-scripts-t36532.html

149

The manual command to get the json file looks like this:


sudo wget -O /usr/share/dump1090-mutability/html/upintheair.json "http://www.heywhatsthat.com/api/upintheair.json?id=xxxxxxxx&refraction=0.25&alts=9144,12192"

The above is for 30000 and 40000 foot but you can change the ‘alts’ parameter to suit your requirements.

Thanks for the replies. Got it going. Goes to prove if you leave the forum for a bit you get behind pretty quick!
Thanks again.

This seems to be the hack-dump1090-mutability-thread, so maybe somebody can help.

I really like the autoselect-feature of adsbexchange.com/ and tried to implement it in dump1090, but failed. ADSBExchange is able to automatically select the nearest aircraft and show the detailed data and the aircraft’s track. As soon as another aircraft is getting closer, it is selected.

There is a function called selectPlaneByHex() in script.js, but i did not find a proper solution where to call it (finding the nearest icao-hex is not the problem).

Any ideas?

152

Yep, that should be possible to add. Give me a little while and I’ll push out a new rev with this as an option. :slight_smile:

Now in place.


Once set this option will check every 5 seconds for the closest aircraft and select it. Selecting an aircraft manually, by clicking on either the table or the map, will toggle auto-select back to off.

(If you are already using my mods, then the only files altered this time were gmap.html and script.js)

154

While your taking requests. (ha)
Would there be a way to make the planes smaller so you could expand the map out and see them in smaller scale
This actually happens for a brief moment when I zoom the map out and it looks really cool.
It would really be handy when the planes are avoiding weather and you could see a larger area of the map.
It would look like this,

155

That makes sense. The size should be somewhat proportional to zoom. I’ll take a look.

156

Thanks a lot for your support! Works like a charm!

157

Well, actually not always. I live close to an airport, when aircrafts land at this airport, the disappear after a while (reaper()-function). In this case, the autoselect stops working and it is not possible to manually select an aircraft - F5 is the only way to start over.

158

Ah! I wondered about that then, because the aircraft closest to me never get reaped, forgot about it. :confused: . Now I know it fails, I’m sure I can fix it! Likely need to add a line to the reaper function.

159

  1. Bug fix for auto-select closest aircraft.
    (This was nothing to do with the ‘reaper’ function. I had forgotten that flights sit in limbo for a while after data stops flowing. After 60 seconds with no data they are removed from the map but are still present in the main table. They get removed completely after 5 minutes. The previous version was locking on to those invisible flights in the gap between 1 minute and 5 minutes.)

  2. Added support for varying icon size with map zoom. This is deliberately fairly restricted so that the icons don’t get too small. The large size is unchanged, the smallest at very wide zoom is 0.4 size) Here’s what that size range looks like:

Very nice. Thanks for the updates.
