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 4.5.0 - SPEC file
 * ogdi-CVS (17 August 2006) - compiled with external proj, expat, zlib
 * GDAL 1.3.2 - SPEC file
 * GRASS 6.2.0 - SPEC file
 * GDAL-OGR-GRASS plugin - SPEC file
 * OSSIM (19 August 2006) - default compilation
 * FWTools 1.0.5 - in /usr/local/FWTools-1.0.5, use "fwtools" alias to add to path

Source code:
 * /home/neteler/software/
 * if taken from CVS, anon-CVS was used
 * configuration is saved in each subdir as "conf_ .sh"

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

Apache
Apache is running with a default configuration. The web site contents goes in /var/www/html. After a machine restart it may be necessary to restart apache with "apachectl restart" as root/sudo.

Geodata processing

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

 * /geodata/markus/vmap0/
 * eur, sas, soa are from 2000, noa from 2002
 * status: downloaded
 * TODO:
 * convert to SHAPE
 * tile into smaller pieces
