このボードで質問が注目されるか試しています...<\/P>
他の人は、時間の経過に伴う歴史的スナップショットを追跡しなければならないジオメトリ／レイヤーの系譜をどのように追跡していますか？例えば、私たちの場合、許可申請が行われた日のゾーニングや歴史的地区、または生息地計画レイヤーがどのような状態だったかを知る必要があり、現在の最新バージョンではありません。<\/P>
fgdbにアーカイブされたレイヤーのコピーを使わずに済む方法はないのでしょうか？ご意見をお聞かせください。<\/P>
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.
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.

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.
