[postgis-users] What likely defects in geodata that must be checked by PostGIS?

[Shaozhong SHI]

The quality of geodata is important.  Human eyes tend to fail in finding
likely errors in geodata.

What likely defects in geodata that is impossible to find with human eyes?
Surely, there are many cases that demonstrate the importance of the use of
PostGIS to find errors in geodata,

Any ideas?

Regards,

David
