All,
I won't be able to make the meeting tomorrow.
But, I wanted to send an update that I've downloaded Colorado Shapefiles of OSM data from Cloudmade to the linux server.
/benchmarking/2011/data/vector/shapefiles
How do these sound for a source for baseline tests for vector data?
Here is some sample output:
2.9M colorado_administrative.shp
178K colorado_coastline.shp
70M colorado_highway.shp
72K colorado_location.shp
14M colorado_natural.shp
498K colorado_poi.shp
15M colorado_water.shp
Pretty tiny, huh?
As far as PostGIS, the direction OSM is going is distributing larger dumps in the binary format that uses Google Protocol Buffers. I would propose importing one or all the pbf dumps for the US for the PostGIS test (from here: http://download.geofabrik.de/osm/north-america/) using osm2pgsql. Or we could simply use shp2pgsql using just the Colorado shapefiles.
