Topographic map
Hi all,

What have people done to generate topo maps of the mesh? I used to use the old bbhn perl script. Is any one have any thing cooking?

Map features
What about the current AREDN map? What are you looking for that it doesn't do?

If I have the right perl
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.

the perl script dose allow
the perl script dose allow for network diagnostics, as that its self populating. The Arden map dose contain location and node type on a map but doesn't generate network topography in the semi real time. The need to monitor /diagnose in semi real time the existing nodes, RF links, Tunnel links and gateways connected to the mesh is valuable. 

A self generating map would need all of the nodes to register there location for the json location to collected, other wise all the data can be qurryed.

The Code dosn't exist in one place at the moment. I hope things can come together for a for a map.

Features and functions
This is not a helpful response. I will ask again - What features and functions are you looking for in a network map?

KG6WXC is doing pretty much the same thing:
https://mesh.sbarc.org/map.php

He said:  "Station popup now shows distance and bearing to the linked stations"

It's pretty sweet.

The perl script generates an image thats rather over whelming, now that the mesh is growing.

is KG6WXC around to comment on his map?

I am.

I am.

I'm actually using those old perl scripts, I didn't realize they were so old.
I saw a network graph and wondered if it would be possible to have that info on a *real* map.
It took me a few months, but I finally had an "AH-HA!!!" moment and all the pieces to do so fell into place.

I have been looking to add a topographic layer to what I have already.
One of my latest ideas is to have the ability to select a point (or a node, hopefully) on the map and find the distance and bearing from any other point.

So yeah, throw your questions my way! Sorry I missed this till now, thanks W6BI!

Im still using them as well..

Im still using them as well... BUt with the topo growing it cluttered!

I like the look of your map! mostly because its using osm because it can be cashed! Ive opend up a few times here on the forum about what I think would look good on a map. How is the map being generated and is it in simi real time? Dose it discover nodes? I looks like you filter out DTD links how about VPN tunnels? The same would be nice for gateways. Do you have Tunnel Links? Im hosting a Tunnel server at W6BB and I have afew Hams back east that connect, but no one in SoCal let me know if your interested in using our topography here in the SFBAY for a mapping test. I like the Distance bearing info, it could be placed with link cost in a hover over popup along with bearing info that occurs at a map level!  Might you share your experance setting up a open street map server?

more info
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.)

All questions but one, can we
All questions but one, can we move your test map into dev like git? I would lke to put a few UI ideas into code. This would give me an opportunity to document a cashing map server.    

I maintain a 24hr Tunnel, There is a lot more routing data being bounced around tho it might be a matter of discussion on another thread. email me direct if you would like to see the status page of the node and or would like to have access. I would much rather have West cost stations connect.

Sorry, it's been a while.
Sorry, it's been a while. I'm not sure about making a git for it just yet, I have made it easier to get setup I think, and I'm not sure I want to open it up quite that much, yet. It's still quite a work in progress. I could use input from others who try to set it up, to try and make it as easy as possible. This map still requires linux, mySQL, PHP and a webserver. (it could be adapted to a windows system, probably pretty easily) Anyone who would like the current code for this, please send me an email: mycallsign@gmail.com I've made more than a few changes since Dec, mostly trying to make it easier for other people to get setup. Just in case anyone is wondering... what I am talking about is the "live" map for our Santa Barbara (and sometimes Ventura) county MESH Network, and it is viewable here: https://www.sbarc.org/aredn-mesh-network/ or https://mesh.sbarc.org/map.php Please send any other ideas this way and I hope you like it and try to set it up for your mesh network! 73 kg6wxc

Stand-Alone Nodes

Eric,

What are those nodes that have no links shown? These nodes are mostly in Simi Valley, looks like about a dozen or so.

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

Thanks!

Orv,

I thought that's what it might have been: nodes that are in the database but show no link quality to anywhere.

73, Mark
