Begin a Vicmap WFS query by selecting a WFS layer. The record must be available as a
Web Feature Service (WFS) layer (listed in listLayers())
vicmap_query(layer, CRS = 4283, wfs_version = "2.0.0")vicmap layer to query. Options are listed in listLayers()
Coordinate Reference System (default is 4283)
The current version of WFS is 2.0.0. GeoServer supports versions 2.0.0, 1.1.0, and 1.0.0. However in order for filtering to be correctly applied wfs_version must be 2.0.0 (default is 2.0.0)
object of class vicmap_promise, which is a 'promise' of the data that can be returned if collect() is used
The returned vicmap_promise object is not data, rather it is a 'promise' of the data that can
be returned if collect() is used; which returns an sf object.
