Topographic map

If I have the right perl script in mind it shows the ETX and all the connections.  This isn't a feature that has yet been put onto the AREDN map (though code is starting to exist to make it possible)

I still use a version of the same script (can't recall if I split off the BBHN version or the OLSR stock version of the script) to generate images tos ee what the links look like across the local mesh.

Its not really pretty looking (its my spaghetti image from my last presentation in Dallas if you recall that image)  but it does have a certain network diagnostic side to it.

To the average user its probably not that useful (the whole point is the network is suppose to 'just work') but it can provide a wealth of data at a glance to know what the network RF links look like.

Thanks! glad you like it! Yes the OSM maps can be legally cached, at least I *think* it can be, but the satellite imagery cannot be unfortunately, not where I am getting it from at least. (It is against the TOS to cache those maps for more than 1 user) I am not caching the maps on our servers at this point, there is no OSM server. Yes that map is semi real-time, and it does discover new nodes, it will even update the database when things change. Say, for instance, a new user gets onto our network but did not put location info into the node setup. My scripts will still find that node, ask it for it's json file, but won't get put onto the map because there is no location info... That user wonders why they are not on the map and we tell them to put the location info into the node, my script will then see the location info and update that nodes information in the database. The other scripts then see there's now lat/lon info and does the rest... The script that goes out across the network and polls each node runs about once an hour. The script that gets the link info runs about every 15 minutes. DTD links aren't filtered out, they are a different color and you usually have to zoom in quite a bit to see them. VPN tunnels are detected and set as another color, I also try and filter those vs other links. I try and detect the tunnels and DTD links based on cost, I noticed that the cost of a tunnel link seemed to stay at a steady "1.0" (a DTD link has a steady cost of "0.1") so I use this info as best as I can to try and tell the difference between the link "types". We do have a tunnel to the neighboring counties mesh network from time to time, but not currently. Our group is a bit leery of tunnels, they tend to make our network freak out and go much more slowly than normal. I can talk to the other guys and see what they think tho. I hope that answered your questions. *edit* I should add, that if you'd like to see that same map, but with a tunnel open to the Ventura County mesh, please look here: https://beachcabin.r1de.net/map.php That is my test map at my QTH that I use for testing new ideas. It is using old data from a couple of weeks ago when we had the tunnel open. (On the testing map, all those long purple "dtd links" you can see, are not actually, they are using other wireless bridges to link together and the AREDN nodes see it a dtd link.)

Mark, when the tunnel between Ventura and Santa Barbara Counties is up the links show; when it's down, they don't.
