We would like to have your feedbacks on our proposition to add new
functionnalities in ftools.
These functions come from the 'SELECTPLUSFR' extensions, developed by
MASSE (french Ministry of Ecology) and available here :
Originally 'SELECTPLUS' is a collection of tools for selecting objects on
vectors historically developed by Barry Rowlingson and supplemented by
Carson JQ Farmer.
The “intersect” tool from the GeoProcessing Tools could be generalized so
that the user can :
Choose to select on the active layer only, or on all layers, or on first
layer (layer "highest" in the order of layers), or on first content
selection (search for all layers and stops at the first layer that returns
Perform the intersection only with selected features.
Choose the operator among Within, Overlaps, Contains, Crosses, Disjoint,
Equals, Intersects (default operator), Touches, DE-9IM operator (with the
possibility to set options)
Choose between creating a new layer, creating a memory layer or making a
selection on a target layer*.
* Selection on a target layer : Selection on target requires that the
active layer (which will provide the target) has at least one selection.
Target selection on all layers are scanned. The active layer itself is
scanned or not according to the option selection.
If this proposal gets your attention and interest, we could be able to work
on it for the version after 2.4.
All feedbacks welcome !
