[OSGeo-Discuss] OSGeo Charter Member Nomination: Stephan Meißl (UNCLASSIFIED)
Classification: UNCLASSIFIED Caveats: NONE I second the nomination of Stephan Meißl as an OSGeo Charter Member. This is another case where I just assumed that Stephan already was. I have worked with Stephan on the MapServer PSC and participated in the 2014 OSGeo Code Sprint in Vienna which again raised the bar in OSGeo Code Sprints. Stephan is already an outstanding member of OSGeo, we just need the formal recognition of it.

I have been working with Daniel for many years and he is one of the most trustworthy and consistently productive people I know. He has always proven to be highly sensitive to community related aspects and has an international outlook, combined with very good English skills. This makes him a good mediator between different regions and cultures, a regularly upcoming issue in our community. This would already make him an invaluable member of the board of directors. But this is not enough, on top of this he also tends to the irksome job of treasurer and has toiled through many down-to-earth tasks that an organization of our size requires to get done. He is also an integral part of the Franco-Canadian local community and a relentless contributor to the MapServer project.

[OSGeo-Discuss] Board Nomination: Jeff McKenna
I would like to nominate Jeff McKenna to the board of OSGeo. As to his qualifications, how much time to do you have? Jeff lives and breathes OSGeo and is one of the most active members of the OSGeo community. He is a friend, resource and gateway to all who have an interest in Open Source (data and software) and OSGeo in particular. Jeff is one of the original charter members (from 2006) and has been on the OSGeo board before (September 2009). Jeff has a passion for OSGeo that is unrivaled by anyone, a big heart, and is considered someone always ready to talk or listen when anyone, anywhere has a OSGeo question, comment or critique. Jeff is very international in his approach to OSGeo and works with and participates with many, many OSGeo chapters worldwide. He has also been an incredible force behind almost all of the international FOSS4G conferences. Jeff would be a humble, strong, active and loud voice for OSGeo. And I'm proud to call him my friend.

[OSGeo-Discuss] Nomination for OSGeo Board of Directors: Jeff McKenna
I would like to nominate Jeff McKeena to the OSGeo Board of Directors. Jeff has been an OSGeo Board member, a founding member of OSGeo, OSGeo Conference Committee chair, MapServer PSC member, FOSS4g Workshop Committee member and founding co-chair of the OSGeo Ottawa chapter. Jeff is very active in the MapServer, GDAL, FOSS4G, and OSGeo communities. He is responsible for running the ever popular WMS Benchmarking effort. Jeff is a tireless advocate for open source, open collaboration and is a big (ha!) welcoming presences in the OSGeo community for many first-timers. Jeff is responsible for the very popular MS4W Mapserver distribution, which is a mainstay for windows users of MapServer. Jeff is a graduate of the prestigious COGS (http://www.cogs.ns.ca/) and is the president of Gateway Geomatics. He has worked extensively with many international OSGeo chapters over the years.

Re: [OSGeo-Discuss] Publishing huge Oracle GeoRasters
Sebastian, I¹d say that improvements to GDAL would be the best option here. I know that Ivan Lucena, who wrote the GDAL GeoRaster driver and has been working with you on debugging, could make changes once the exact issue has been discovered. This would improve mapserver, Geoserver and any other system that uses GDAL. Mike -- Michael Smith US Army Corps of Engineers Remote Sensing/GIS Center Hanover, NH On 8/16/10 5:29 PM, Sebastian E.

I say weird because I'm having performance issues with LOW level of the pyramid. MapServer in some how does a SELECT on ALL the blobs of the current pyramid level !

Re: [OSGeo-Discuss] Raster data on RDBMS
Ivan, Those numbers look impressive. We are just starting to set up some new hardware here and I plan to do some testing also. Perhaps we can collaborate and come up with a test suite in order to track these numbers across builds.

The default blocking used by the GeoRaster driver is (256, 256, 1). That is good because GeoTiffs doesn't tile on band space.

I would imagine that if I run gdaladdo to add Pyramids on the GeoRaster one application could take advantage of it by telling Oracle to cache the BLOB in memory. So the next time a user zoom-in the performance would be even better. I am trying to setup a mapserver experiment on that issue but for now I would like to keep my analysis on that very simple process of extracting a subset. Best regards, Ivan ---Original Message--- From: Paul Ramsey [EMAIL PROTECTED] Subject: Re: [OSGeo-Discuss] Raster data on RDBMS Sent: Oct 29 '08 05:00 The data is chunked in Oracle into tiles, so unless you tile the TIFF as well you aren't really doing a direct comparison. Even if you end up with the same numbers for both processes, I'll still be impressed, since I assumed Oracle would have a higher overhead. P.

But this time I would like to present some number. As long as I could recall there was basically two major arguments contrary to storing raster on RDBMS. One very pragmatical: Why waste precious process time with the overhead of dealing with queries, tables, client-sever back and forth just to get the data from BLOB fields on a database when you can get it directly from the file system?. The other argument was semantical: Why store raster on RDBMS if in general we are not expecting to have a transactions on that data? I cannot argue against the second one. I basically agreed with that but after seeing how fragile and complicated even a well defined structure of folders and files could be I would vote in favor of the good and old relational model. That is my experiment. I downloaded two free data samples from Naveteq website. Two geotiff files with the same size and number of bands (14336, 14336, 3): [EMAIL PROTECTED]:~/Data du -k Barcelona_2007_R2C2.TIF 602828 Barcelona_2007_R2C2.TIF [EMAIL PROTECTED]:~/Data du -k San_Francisco_2006_R1C2.TIF 602828 San_Francisco_2006_R1C2.TIF Then I loaded those images to Oracle Spatial GeoRaster using GDAL.
