Ok, in a broader sense the catalog can be seen also as a "caching system" (were all [PD] imagery sources could be presented, saving time for the OAM "integrators" so that they don't have to compile the list over again from the various data/imagery providers) >> On the other hand, there's still no news regarding the OAM infra (I >> don't think I've seen many past pointers on talk@ regarding its >> existence; just double checking).

I find the overall OAM documentation to be fairly "distributed", as: - the www/wiki is stale for some months (ping Cristiano Giovando, oam.org) - the www/wiki (still) includes past plans that could send newcomers on false trails - there are several good hints/pointers spread over various posts in the mailing list - ... btw: where can I see the latest doc regarding the (current) OAM architecture? On the "infra" side it would be nice to have a list of building blocks with their ownership/donor, i.e. OAM is relying on: - www.openaerialmap.org, owned by CG, hosted at BlueHost - mailing list hosted by ..., available at ... - source code hosted by GitHub at ... - latest documentation published at www/doc - server #1 can be donated by NN - server #2 can be donated by NN - storage TB can be donated/used from NN - AWS (credits donated) by NN for powering the catalog service/API - ... For newcomers, I think up-to-date documentation is a must have in order to quickly identify the gaps and allow any contributor to make the most of their time/work on OAM. P.S. I'm new, so I have questions. many :-) Thanks, Ciprian ---- A* > http://oam.osgeo.org/ > > is up and running, and has been for more than 6 months; it has > thousands of images in the catalog, and tools in > > https://github.com/oam/oam > > are written to run against it, producing output like: > > http://processedoam.s3.amazonaws.com/mit-knight-foundation-sm.jpg > http://processedoam.s3.amazonaws.com/4000pxdemo.jpg > > Although there is no hosting being done 'at' OAM, part of the > revamp and design is so that there doesn't need to be: other than > the catalog, all the pieces can be trivially distributed, meaning > there is no need for large scale centralized hosting. _______________________________________________ talk mailing list [email protected] http://host134.hostmonster.com/mailman/listinfo/talk_openaerialmap.org
