Thanks Jukka for your response,
In particular for the pointer to the "bounding box with every feature" feature.
What puzzles me is why there is no third option – that you propose – to return
the BBOX for the while collection. This behaviour makes in most situation
ultimate sense, as as I said, I am yet to see a heterogeneous SRS collection.
"If bounding box is returned with every feature then it is returned also for
the FeatureCollection." - it would be sufficient to have it only for the
FeatureCollection, dramatically reduing the transmitted message.
I would like to address you comment: "In real life there are users like us who
want to disable bounding boxes because computing them can be awfully slow.
Thus if you are building something that may read data from servers which you
cannot control you should take into account that boundedBy information can be
lacking.
"
I acknowledge that the situation you describe is valid and common – but I would
argue predominantly in situations where you actually CAN handle the servers. If
you can not, and should not make assumptions about the data, you need SRS
information with the collection. Otherwise, you cannot interpret the
geometries' coordinates. Anyway, the switch for this behaviour should be
available.
Just a note – I tested Mapserver WFS, Deegree WFS and plan to try the 52 North
WFS tomorrow. The first two include the envelope and the bbox for the entire
collection. As a long-standing fan of Geoserver, this does not make me feel
good :)
Cheers,
M.
