Geodata processing at telascience.org

Background

As one objective of OSGeo, we want to generate/update/enhance existing free geodata for the community. This comprises re-packaging, data storage in convenient formats, tiling and other.

We are kindly supported by http://telascience.org (available resources).

Installed Software

I have installed the following software packages on geodata.telascience.org:

• geos 2.2.3
• proj-CVS (17 August 2006) - compiled with datum files
• ogdi-CVS (17 August 2006) - compiled with external proj, expat, zlib
• GDAL-CVS (17 August 2006) - compiled with pg, sqlite, mysql, ogdi, python, geos
• GRASS-CVS (18 August 2006) - compiled with pg, sqlite, mysql, C++, LFS support
• OSSIM (19 August 2006) - default compilation

Source code:

• /home/neteler/software/<software>
• if taken from CVS, anon-CVS was used
• configuration is saved in each subdir as "conf_<software>.sh"

Binaries:

• all binaries are installed into /usr/local/*
• /usr/local/lib was added to /etc/ld.so.conf

Geodata processing

• data are stored on geodata.telascience.org in /geodata/<user>
• only root/sudo can add further directories in /geodata/ (FrankW, markusN, hobu, ...)
