I am producing a road map (for print and online). I was thinking of using creating a geometric network with my roads, for editing purposes mainly, but I would like to know any critical downsides of selecting this strategy. This is why I turn to You.
All the examples I can find on the web (including Esri) are utility related -- either power, water or sewerage. So, if this concept is created with those in mind, is it useful for road editing too?
The reasons I find geometric networks attractive for road editing are:
- Excellent editing features.
- Automatic clipping of existing segments, when a new segment is drawn to them.
- Existing annotations and representations are not lost, when a new road is added -- the automatic clipping preserves annotations and representations. The Planerize tool loses annotations and representations.
- Lightning-fast identification of disconnected road segments.
- Fast identification of dangles (send by analysing for loops
- On-the-fly validation of new features.
This far, I have identified following downsides:
- Closed line features are not allowed
- Roundabouts are really hard to create without the Circle drawing tool (following the above mentioned limitation).
- Not being able to have a topology within the same featureclass.
Are there any critical issues that should prevent me from using geometric networks?
