Hi,
wxvdigit allows in trunk (r35872) and devbr6 (r35873) to add
automatically centroid to valid areas. You can set this functionality
in the settings - 'Attributes' -> 'Digitize new area'.
* add centroid to left/right area
When new boundary is added, left/right area is checked. In the case
that area is valid (closed) and has no centroid, new centroid is
added.
* do not attach category to boundary
When digitizing new boundary, category is attached only to the newly
added centroid.
Testing welcomed.
Seems to work alright, although I do find this potentially dangereous as
users might not really understand what they are doing... (but I am
conscious of the fact that this functionality is what most people would
expect...) At least, I think that "do not attach category to boundary"
should be the default when "add centroid to left/right area" is set.
Actually, I think it should always be the default and that if a user
want categories for boundaries she should set it explicitely.
A few +/- related remarks:
- Could manual entry of category number be part of the pop-up window
that shows up when you finish digitizing a feature. Having to go back
into the paramters window for changing the category for every feature is
very cumbersome.
- Trying to digitize a polygon which uses one boundary of another,
existing polygon, I understand that I need to add new vertices to the
existing polygon at the places where the new polygon boundaries touch
the existing one. However, whatever I try, I cannot add new vertices.
When I select the tool and click on a boundary I see a red cross at the
place I clicked, but I cannot get it to stay.
