Hi Chris,

I believe the (best) source for "formal/legal ... municipal boundary positions" would be Fazel Hoosan @ the Municipal Demarcation Board.
His contact details: 087 150 4424 / fazel at demarcation.org.za 

Best regards

Ryk

We believe good spatial information leads to superior planning, diminished project risks, improved feasibility assessments and efficient resource utilisation.

Hi Gavin,
I did see the one using "another layer", but that is problematic as when one is digitising (say) a town road network you would want to honour the straightness of the roads and then intersect them afterwards.

If you're doing it while digitising I would rather set up snapping perfectly then node intersections while digitising. As simple as stopping a line and starting a new one instead of just clicking a vertex at an intersection. 



Hence "popping out" to other facilities just messes up your work-flow.

Will look at the scripting options  - for now this is just a training exercise in teaching digitising principals.

Thanks & keep well,
Zoltan

Hi Chris, 
Contact the Demarcation Board, or download from their website.
They have the 2011 and 2016 boundaries available.
