Verfolgung der Genealogie von Geometrieänderungen / historischen Momentaufnahmen in der Zeit

Question

Ich probiere dieses Board aus, um zu sehen, ob meine Frage Beachtung findet...<\/P> Wie verfolgen andere die Genealogie von Geometrien / Layern, bei denen wir historische Momentaufnahmen in der Zeit festhalten müssen? Zum Beispiel müssen wir wissen, wie die Zonierungs-, historischen Bezirks- oder Habitatplanungs-Layer am Tag der Antragstellung eines Permits aussahen, nicht wie die aktuellste Version ist.<\/P> Gibt es keinen Weg ohne Kopien von Layern, die in einer fgdb archiviert sind? Gedanken?<\/P>

Of course! If the parcel fabric is overkill, you could just put "date created" and "date retired" fields on your features and manage them that way. Would still let you do some time slider action to interactively visualize how things looked.

Josh, thank you so much for this comment. My team has been tossing around the idea of parcel fabric potentially meeting this need without knowing of any actual use cases, so this is super great to hear you're using it successfully in this way. We'll do some research in this area.

A parcel fabric works great for this kind of thing. We have a whole parcel fabric just for zoning, permits, and other ordinance-related items that aren't necessarily tied to property ownership, but which we want historic information about.

It would take a little more work to pull the parcel fabric's record dates into the features, but is perfectly doable. The end product is a time-aware layer of districts, etc., that you can browse by date.
