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
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, ...)
