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
- Markus Neteler
- Frank Warmerdam
- Martin Spott
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, ...)
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)
- There is now also a PostGIS installation of VMap0 on the xxx telascience machine (define access possibilities here)
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/
- database dump in dump_17aug2006/
- docs in docs/
- fetch.sh script in the dump/ directory for future downloads
- status: downloaded
- TODO:
- convert to SHAPE?
- insert into PostGIS? - see docs/geonames_dump_into_postgresql.txt
