I think using this mailing list is the most appropriate channel for<br>
reaching out to the Czech community.<br>
<br>
I am a bit worried about the source of the imagery you will be using.<br>
Czech Republic is in quite diverse terrain so imagery is sometimes<br>
very off. I believe most of the roads are already mapped and already<br>
aligned using czech cadastral maps (cuzk:km) so I would suggest to use<br>
that layer for reference too to avoid making things worse:<br>
<br>

<br>
I would be also interested in more detail on improvements for cities.<br>
What does it mean? Changes to landuse areas? city points? Something<br>
else?<br>
<br>
We also have many waterways and highway networks imported so they<br>
still often intersect without the correct bridge/tunnel. What methods<br>
are you going to use to distinguish these? Just publicly available<br>
satellite imagery? Or you will just bridge everywhere?<br>
<br>
Regards,<br>
Jakub<br>
