[OSGeo-Discuss] 3.0 OpenLayers code sprint - call for sponsorships
Hello, This mail is a call for sponsorships to organize the « 3.0 OpenLayers code sprint ». This event enables European OpenLayers community and OpenLayers developers from around the world to meet. The likelihood of an OpenLayers code sprint (for version 3.0) is taking shape. It is scheduled to take place for 4-5 days during the month of March 2009 in France, in a remote and isolated part of the Alps (a quiet place to achieve better work on this major release!). The cost of the stay (travel expenses excluded) is about 750 € per person. As organizers, we want to cover all incurred expenses during the event as well as the maximum of travel expenses i.e. a budget of about 10'000 € for 6 persons. Only the time spent at the event would then be at the charge of the developers (and/or their respective organization/company). Any kind of support is welcome... A PayPal account is an easy means to carry out a sponsoring activity, even a small one, as an individual or as a company's endorsement. For a larger sponsorship, please do not hesitate to contact me or Virginie Jourdan directly – virginie.jourdan at camptocamp.com : we can suggest a communication partner plan (based on OpenLayers community's sponsoring activities). Thank you for supporting this initiative which will encourage the promotion of French and European Open Source Geoinformatics within the OSGeo.

Re: [OSGeo-Discuss] 3.0 OpenLayers code sprint - call for sponsorships
Hi David, this event seems really a good idea. I have a couple of doubts: why not to join the OSGeo Hacking Event in Bolsena [1] in June? maybe two hacking events so close in time are too many. This year the event in Bolsena has been successful to many, afaik. Well at least to me. :-) The other problem I have is that I will go to the Spanish FOSS GIS [2] meting of Girona in mid march. ciao lorenzo [1] http://wiki.osgeo.org/wiki/OSGeo_Hacking_Event_2009 [2] http://www.sigte.udg.es/jornadassiglibre/ David JONGLEZ wrote: Hello, This mail is a call for sponsorships to organize the « 3.0 OpenLayers code sprint ».

[OSGeo-Discuss] State of OpenAerialMap
(This message is CCed to several lists; please reply *only* to the OpenAerialMap talk list. The list requires subscription. Subscription information is at: http://openaerialmap.org/mailman/listinfo/talk_openaerialmap.org. Thank you.) State of the OpenAerialMap == For entirely too long, I've been putting off this email. I apologize for that. OpenAerialMap started as a project about a year ago, when I was working with some aerial data provided by a number of sources. Instead of putting together all of the different sources, I was interested in combining them into one world-coverage basemap, to act as an open replacement for the Google Maps imagery layer for purposes where the highest resolutions are less important, or other data can fill in the gaps. In part, this project was also started with the idea that it woul be able to take on a supporting role in the hosting of small datasets, like those taken via kite photography projects and drone-flown imagery. In the beginning, the idea was simple: take any data that was available on the web, convert it to uncompressed geotiffs in EPSG:4326, spit out some tiles, and call it done. We started with support for GeoTIFFs, and expanded into supporting both WMS and GDAL tileindexes. The site gained some traction, and started getting people from different places around the globe -- peopel who had no idea of how to work with raster data -- attempting to contribute. From about February of this year, the situation continued to get worse. With no active community around the project -- in part due to technical limitations, in part due to any active groups seeking to help build that community -- the project stagnated. With the easy problems solved, only the hard problems were left, and the hard problems tended to be hard to solve. Some of the issues that have been brought up repeatedly: * The 'base' dataset for most of the world is a landsat dataset provided by i-Cubed. The licensing of this dataset is unclear. It was provided to... someone. The usage restrictions on it were not made clear. It is possible that this dataset is free to use... or possible that it's not at all free to use. Because this dataset is the base for most of the world -- and appears to be a relatively well-served landsat dataset, something generally rather rare -- most questions about OpenAerialMap come down to the rights of use of this layer. There are clearly several paths to solving this particular problem. The first path that I've been trying since OAM started was to actually get some kind of statement about the rights attached to this layer. Unfortunately, that path has failed miserably so far, so it seems that it is probably best to abandon this path, and treat the current landsat imagery served via OAM as encumbered with copyright restrictions. This leaves a second path available, which is to build a landsat service which is not encumbered. I believe this should be possible to do, and I'm sure that the group of people interested in seeing a free/open OAM will be glad to step up. * The process of adding data to OAM was, practically speaking, impossible for anyone who was not an expert to follow. There are a number of technical reason for this, but I think that it is completely reasonable to say that these problems can only be resolved by participation in the project from people who are at least vaguely knowledgable about working with large geographic data. I would suggest that what the project really needs is a way to upload data to be processed by the OpenAerialMap server itself, rather than depending on users to upload 'appropriate' data. This means developing a processing queue to convert data from any available format to one more suitable for use in OAM. The discussion of what is 'appopriate' for OAM requires further discussion as well. Combined with this should be improvements to the TileCache, which is currently never expired. * Storing a whole world sized dataset at the maximum resolution available for the whole world -- even at a single given point in time, ignoring all other constraints -- is a *really big* 'problem' to solve. One of the things that caused my work on loading data into OAM to slow down -- beyond a lack of interest from any other participants -- is not that there was too little data, but instead that there was too much. There is 1M or 2M data available for the *entire US* taken every year. This data is gigantic -- and it's only a small portion of the total data out there. This one, I don't have a real solution for. I don't see the path out of it with any resources that OAM currnetly has available or on offer. * Related to the above, some of the technical possibilities -- specifically, compressing the data using lossy compression -- has issues that are difficult to make happen; these could be

David, It looks like this is shaping up to be quite an event! The dates on the wiki page still seem very open, but you mention mid-March. Can we be more precise with the dates that are being considered? March is already not that far away and it would help to have a tighter window for us to start pitching this to mgmt. As for the lodging, all these ski chalets sounds wonderful. The only thing I would suggest is that, given the nature of this work to be done (sounds to me like probably more debating than coding, necessarily) it will be crucial to have a big meeting space and a projector so that people can make presentations to the group as a whole. It is great to see CampToCamp stepping forward to organize this event, I think it will be a great opportunity to get some good work done. Erik ps.
