Hi everyone,
I have some MID MIF and TAB files that have differing geometries in them
(ie: points, plines and regions).
QGIS seems to simply (and silently!!!!) stop reading that import file as it
hits the first non-similar geometry.
Is this the case? (or does it skip other geometries and read the entire file
reading only the first-found geometry types?)
Tim/Anyone: Can you comment on this filtering or error-exiting?
Yes we currently only support 1 geometry type per layer. How mixed
geometries are dealt with is provider dependent
I feared this.
This is a massive showstopper for any serious GIS implementation that
needs strong topology.
Take for example a sewer network that has been captured from plans.
At some later stage you GPS capture the manholes and want to adjust
their positions in your GIS database - but you also then need to move
the pipes.
Yes, you can spatially snap to pipes in other maps/layers, but snapping
without carefully selecting your search radius could lead to other
errors being created without your immediate knowledge thereof.
There's nothing to beat a topologically correct database. (Yes, I know
I'm selling snow to Eskimos :-) )
Is "currently" on the cards to soon become "we no longer" ?
Thanks for your comments.
Regards,
Zoltan
