In the city of Karviná, in your example, these two industrial
buildings are much larger in reality than imported:<br>
<br>
<a href="http://osm.org/go/0LZc_9WgW?m=">http://osm.org/go/0LZc_9WgW?m=</a><br>
<br>
<a href="http://osm.org/go/0LZc_2625?m=">http://osm.org/go/0LZc_2625?m=</a><br>
<br>
But they can be corrected in JOSM easily. And it is not a big deal.<br>
<br>
An excellent stadium and a soccer pitch are not mapped here: <a
href="http://osm.org/go/0LZeTNDQl-?m=">http://osm.org/go/0LZeTNDQl-?m=</a>
, it is not like some shed missing. But in general, the map of
Karviná is impressive.<br>
<br>
Sometimes municipal databases were created in 90s, with obsolete
equipment, by employees who could not care less. But sometimes they
are of good or medium quality.<br>
<br>
An import can be reviewed and corrected with satellite imagery or a
survey. So both approaches are <span id="result_box"

<pre wrap="">... did an awesome import of addresses
and buildings. Now compare it with the Polish side:
