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-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, ...)

Data: VMAP0 1:1Mio World Vector Data

  • /geodata/markus/vmap0/
  • eur, sas, soa are from 2000, noa from 2002
  • status: downloaded
  • TODO:
    • convert to SHAPE
    • tile into smaller pieces
    • cleanup attributes
    • remove annoying grid lines (dissolve in GRASS)
    • enrich country maps with population data (see here for inspiration, I have their SQL code somewhere)

Data: GSHHS World Costline Vector Data

  • /geodata/markus/gshhs1.5/
  • from Sept. 2004
  • status: downloaded (original server disappeared, but MN had a copy)
  • TODO:
    • convert to SHAPE
    • tile into smaller pieces
    • cleanup/add attributes

Data: Gazetteer data World from geonames.org

  • /geodata/markus/geonames.org_17aug2006/
  • database dump
  • status: downloaded
  • TODO:
    • convert to SHAPE?
    • insert into PostGIS?
