Hi Dev list,<br>
Is anyone aware of a plugin that can:<br>
<br>
<ul>
<li>auto-snap (make concurrent) borders between adjoining polygons
(perhaps also in different map-layers)<br>
(Like topologically aligning cultivated land polygons with river
banks or other adjoining polygon features)<br>
<br>
</li>
<li>auto-snap (make concurrent) polygons borders with line
features (perhaps also in different map-layers)<br>
(Like topologically aligning cultivated land polygons with road
or other line features)<br>
<br>
</li>
<li>Drop in vertices at places where features intersect each other
(perhaps also in different map-layers)<br>
Like a road crossing a field (but not dividing the field into
two pieces), or a bridge feature running on top of a road
feature (placing vertices on the road feature directly under the
start & endpoints of the bridge line)</li>
</ul>
<p>It would be cool if this could be automated, with the ability to
set snapping tolerances, and choosing whether to have a master
feature set to move to, or to average the gap between the features
(ie: move both features to the averaged common boundary). The
final result must have identical vertices in both the adjoining
features even if they are in separate maps, and the ability to set
a master (aka unmoveable) feature is critical in case you need to
align more than 2 features (eg: Municipal boundary with cultivated
land with road), as you would not want a previously aligned
feature set to "walk" whilst you are aligning a further feature
set to it.<br>
</p>
<p>Thanks & chat soon,<br>
