Smaller data for testing

[sowinski]

Hi,

I use this file:
http://download.geonames.org/export/dump/
cities15000.zip : all cities with a population > 15000 or capitals (ca 25.000), see 'geoname' table for columns

for testing. But it is still to large and takes a lot of time.
I tried to remove 90% of the file. But just removing entries is ending en errors.

How can I create my own file? For example a cities100000.zip on my own? Or find more data?

Thank you
