In one of my SotM 2011 talks, I suggested that OSM
should have regular extracts of metropolitan areas for major world cities and
their surrounding areas, regardless of state or country. This is a repository
for a bit of code to make that real. I’ve decided to use Amazon S3 to host files,
and EC2 to do the extracting. extract.sh is a script that performs the
actual work with Osmosis and
terminates its host machine upon completion.
To use Extractotron yourself, put this brief shell script in your EC2 user-data:
#!/bin/sh
K=<your AWS access key>
S=<your AWS access secret>
B=<your bucket name>
U=https://raw.github.com/migurski/Extractotron/master/extract.sh
curl -s $U | KEY=$K SECRET=$S BUCKET=$B sh > /mnt/progress.txt 2>&1
Currently, the cities list is very short. Help me expand it by modifying
cities.txt and sending a pull request via Github.
