Geodatabase Topology on a portion of data

WesleyStreet — Wed, 12 Jun 2013 17:53:38 GMT

My problem is this.

I track and map parcel data and this is stored in an SDE feature class. Also in this feature class is larger polygons like neighborhoods etc. I want to be able to run a Geodatabase topology only on my parcel data. The topology doesn�??t find cracks if there is a large neighborhood polygon behind it. I cannot make a change or split the feature class its self because it would require a schema/architecture change to the database. Also there are lots of views, services etc. that would not work if there was a change to the way the data is stored.

Could I create a map topology for a view since those are stored as feature classes? That way I could edit and change the original feature class, then the changes would get pushed to the view, and then pushed to the topology?

Do you happen to have a Subtype for the feature class to delineate from parcels and neighborhoods?

I know you can specify rules based on Subtypes. This would allow you to specify only your parcels to follow the topology.

That isn't going to work fo us I don't think. I have used subtypes and domains before and I don't think they're applicable to how our information is being stored/used.

We were thinking about using a replica database for to topology. However, do we make a topology and rules in the original database and then replicate that but filtering what features we are replicatings? Or can we replicate the database with the features queried down to what we need and then use database topology? I am going to go with a no on the last one though because it hasn't worked yet today. The former is out because once again all the links would be broken for everything that references that feature class.
