A few weeks ago, after reviewing nodeshot, nodewatcher, and others, NicoEchaniz decided to start AlterMap, which literally means "yet another map"
the idea, though, is to make it as flexible as possible, so that it can be adopted / backported to existing networks. Very much like the interop-dev effort, but skipping the name voting part :)
the outstanding difference with current map solutions, and main appeal, is that it mixes CouchDB, JSON, Backbone and Leaflet , so: * the database is schema-less, (in order to accomodate the irreconcilably different db schemas from guifi.net, ninux, athens, wlan-si...) * it can be implemented as a CouchDB applet, so the frontend can be served entirely from a uhttpd running on openwrt, serving simple js. * couchDb implements native synchronization, which enables from the start the possibility of downloading a copy of the db to a cellphone, creating a node offline while "in the field", and syncing it back afterwards, a feature the guys at guifi.net are currently trying to resolve. * another possibility is syncing *between* different networks, so that for example ninux pisa can have its local couchDb where it maintains pisa' nodes, and syncs two-way with ninux rome using native couchDb support. * an extreme possibility of the above point, would be having a frontend to a *world* map of all WCN nodes. The schemas of each network would be different, so not every bit of information would be displayed in that frontend, but at least name and gps location could easily be aggregated. * as communication is done in JSON, current map implementations don't need to be abandoned all of a sudden ; each network could code a simple middleware that translates JSON between its current solution and CouchDB, and make the transition smooth. * We started it with a batman-adv compatible-map idea in mind, but again, as it is JSON, a script simply turns batctl output into JSON, so any protocol can easily be scripted to talk JSON as well. (in comparison, Nodeshot needs to make batman-adv output look like OLSR format, instead of a "neutral" notation like JSON.) * Leaflet is actively developed, small, and already offers touchscreen features for mobiles. * there's already also crazy ajax that enables near-realtime visualization of data as it gets updated from any data-source. It might sound far-fetched, but the map could aid mesh node positioning by giving visual feedback on complex data such as multiple links as is the case with neighbours on IBSS clouds.
Work so far is being done on https://colectivo.altermundi.net/projects/altermap/wiki
almost all of the magic is done by CouchDB, etc, so the actual code is a bunch of js, mostly glueing together "the shoulders of giants" ;)
What do you people think?
Paul, Do you think this could have a positive interaction with Serval Maps? I see these items in the roadmap: * Share mapsforge data via Rhizome * Explore options for export of geographic information to other systems as required maybe these could be leveraged by using couchDB and JSON?

Hi all,
Is there an obvious choice for web-based visualisation of batman-adv networks? We currently use a custom product (SPUD - http://dev.villagetelco.org/trac/browser/spud/trunk/INSTALL) built specifically for Village Telco but would prefer to join our efforts to a broader community-based effort. I am aware of
Nodewatcher http://nodewatcher.readthedocs.org/en/latest/installation.html and Nodeshot http://wiki.ninux.org/InstallNodeshot
but both of these take a little adapting to batman-adv. Is there anything out there that has been developed specifically for batman-adv?
For our local Freifunk community here in Lübeck we are currently using a home-brewed solution called 'ffmap-d3' developed by Nils Schneider to visualize our batman-adv topology. Source code is available on github:
http://tcatm.github.com/ffmap-d3/
It is still quite new and still gets its regular tweaks, but this page should already give you an idea about how it looks like, its current features and general usability:
http://holstentor.metameute.de/mesh/nodes.html
Not sure whether this is something you are looking for, but thought I'd mention it anyway.
ffmap-d3 is quite beautifully done, very elegant rendering of nodes although we are looking for something more GIS-oriented. Both are worth exploring though. Thanks.
Cheers... Steve
