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).

Status of geodata.telascience.org

Participants

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/<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

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/<user>
  • only root/sudo can add further directories in /geodata/ (FrankW, markusN, hobu, ...)

    • convert to SHAPE
    • tile into smaller pieces
