[OWSLib-users] OGC time filter on WFS

[Laurent Besnard]

Hi there,


I've been searching a bit everywhere in the code/issues ... regarding an OGC time filter capability in OWSLib without any success.

The only way I have managed to achieve this so far was do write some dirty xml in my own code. But I'm sure I'm missing something:

from owslib.fes import PropertyIsGreaterThan

wfs_filter_time = "2019-02-18T03:04:00"
wfs_property_filter_time = 'TIME'
wfs_date_format="yyyy-MM-dd'T'HH:mm:ss"
wfs_filter_slevelmax = PropertyIsGreaterThan(propertyname=wfs_property_filter_time,
                                             literal=wfs_filter_time)

# since the function feature doesn't seem to exist, have to create the query manually
filterxml_time = '<ogc:{property_filter_type} xmlns:ogc="http://www.opengis.net/ogc"><ogc:PropertyName>{wfs_property_filter_time}</ogc:PropertyName>' \
                 '<Function name="dateParse"><Literal>{wfs_date_format}</Literal><ogc:Literal>{wfs_filter_time}</ogc:Literal></Function>' \
                 '</ogc:{property_filter_type}>'.format(property_filter_type='PropertyIsGreaterThan',
                                                        wfs_property_filter_time=wfs_property_filter_time,
                                                        wfs_filter_time=wfs_filter_time,
                                                        wfs_date_format=wfs_date_format)


Is there some proper way to do the equivalent with OWSLib ?

Regards
Loz
