Hey Pascal,

currently still manually, will be hopefully fixed this week. And then
once per 1 or 2 days. Also contact me if you need an API key for our Web
API.

You will have to experiment a bit. Keep in mind that you should not
increase it too much as some real islands will then being unroutable.

It will give you 'not found' error

yes, via index.highResolution=500 which is in meters. Increasing it to
1000 is probably okay but the more you increase the slower the location
lookup will take. We'll improve this probably in one of the next
versions to make the initial search rectangle smaller but then expand
the search if nothing was found ...
Regards,
Peter.
