You may already have heard from me about the GeoVation Awards program that we launched a couple of weeks ago. GeoVation has an awards pool of £21,000 to help some innovative ideas get started. The only requirement is that they use geography and create some social, economic or environmental benefit. You can find out more about the Awards Program and browse through the ideas already in discussion at https://challenge.geovation.org.uk/ There are two groups of people that we are trying to reach and connect - people who have an idea (maybe there is something that you wrote down on the back of an envelope or beer mat ages ago) and people who have the skills and energy to help the ideas become a reality (you could be a developer, a designer or a commercial person). Hopefully we can facilitate the connections that will help to turn ideas into ventures and then into award winners by January. If you want to learn a bit more about the GeoVation Awards Program, meet a few of the ideas owners, get your creative juices flowing with some drinks and nibbles why not come along to the GeoVation Ideas Forum at the RSA in London on November 2nd. Registration is free at http://gvideas.eventbrite.com/ If you know anyone else within your work or social networks who you think my be interested in winning one of the GeoVation Awards please forward this invitation to them Thanks and look forward to seeing your GeoVations Steven -- Regards Steven Feldman KnowWhere Consulting Mobile: +44 (0)7958 924101 Web:http://GIScussions.blogspot.com Twitter: http://twitter.com/stevenfeldman This message has been checked for viruses but the contents of an attachment may still contain software viruses, which could damage your computer system: you are advised to perform your own checks.

[OSGeo-Discuss] GovHack 30,31 October - Climate Challenge mashup?
Hi all, I saw the following on another mailing list I am on thought I'd post it here in case any Climate Plugfest people are reading: -8---8 GovHack is a free, intensive day and a half exploring ways of creating mashups and applications with government data and services, and most importantly building some applications before the event is over. http://govhack.org/ -8---8 I was thinking it would be really cool to offer up the CSIRO and BoM data into the mix as they are fresh and topical: http://external.opengis.org/twiki_public/bin/view/ClimateChallenge2009/WebHome Can someone involved with the plugfest please consider letting the GovHack people know about any climate change data they might be able to add to the fray.

[OSGeo-Discuss] WMS Performance Shootout presentation/results
For those that did not make it to Sydney, here is the WMS Performance Shootout presentation with results (GeoServer vs MapServer): http://www.slideshare.net/gatewaygeomatics.com/wms-performance-shootout MapServer: power users who manage MapServer sites with high loads/map draws should take note of the results of MapServer CGI vs MapServer FastCGI, even in the case of Shapefiles and Rasters (yes, quite surprising). All: a lot of credit should go to Andrea Aime from GeoServer who worked very hard in bringing the MapServer team up to speed to learn the testing process. It was a great experience and we're already looking forward to next year. -jeff -- Jeff McKenna FOSS4G Consulting and Training Services http://www.gatewaygeomatics.com/ ___ mapserver-users mailing list mapserver-us...@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users -- Jeff McKenna FOSS4G Consulting and Training Services http://www.gatewaygeomatics.com/ ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

Re: [OSGeo-Discuss] WMS Performance Shootout presentation/results
It was really interesting. The very close results suggests to me that the bottlenecks were external to the WMS and more related to external limitations like the ability to supply things like I/O. It would be interesting to have profiling data on where the response time was spent. For Mapserver it'd be a simple case of running Valgrinf and KCacheGrind: http://kcachegrind.sourceforge.net/cgi-bin/show.cgi/KcacheGrindIndex Case point. We had an in house app for crunching big raster and KCacheGrind showed us that an external library was the biggest bottleneck. A.

RE: [OSGeo-Discuss] WMS Performance Shootout presentation/results
I agree wholeheartedly. It looks like the bottleneck was the database. I've been privy to some MapServer tests done by testing teams over several months and the result there was always deploying the data with long update cycles to the middle tier disks instead of using the database. Only then could the performance of the actual map servers be evaluated. Performance shootouts/testing take time to do correctly as each run teaches you more and more about how your deployment architecture affects the results.

Craig Miller ha scritto: I agree wholeheartedly. It looks like the bottleneck was the database. I’ve been privy to some MapServer tests done by testing teams over several months and the result there was always deploying the data with long update cycles to the middle tier disks instead of using the database. Only then could the performance of the actual map servers be evaluated. Performance shootouts/testing take time to do correctly as each run teaches you more and more about how your deployment architecture affects the results. Actually running the benchmarks it looked the CPU was the bottleneck, we had 25% cpu load in the single test (so 100% of the one CPU used by that test, out of the 4 available) and during the higher loads the CPU usage was jumping between 80% and 100% (so almost all 4 cpu maxed out). The database server was hardly using more than 25-30% of its CPU and the network shouldn't have played the bottleneck either (past experience suggests it takes a tilecache to actually turn a 100Mbit line into a bottlenek), thought we don't have numbers for that During the benchmark I had very little time to run profilers, but the few times I've tried in GeoServer the time seemed to be splitted quite equally between data fetching, actual drawing, and output image encoding... which is kind of the worst thing you can get out of a profile run, since it does not point to any culprit. Getting a profile out of MapServer is surely going to be interesting, the codebase is smaller and there is no garbage collection going on so the results should be clearer. Looking forward to see those results :-) Cheers Andrea ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
[OSGeo-Discuss] code sprint before or after the conference
Hi list, today I was at the code sprint in Sydney, and after a whole week of conference with the associated beers and late nights, nothing much productive came out of me unfortunately, which was to be expected. So for next year in Barcelona, I would really appreciate it if the code sprint code would be *before* the conference starts. How do other people feel about this?
