Tracking changes to Parcels

    Does anyone have a system in place to track changes and display them on County GIS websites to Property boundaries.

    Ex. If a change to the boundary of a lot would include/remove additional lots adjacent to the property boundary I would want to see that change and all previous changes.

    Maybe something like google earth's historical aerial bar.

    I copy the current parcel to another layer called history before I make the changes. I've colored the linework a different color for each year (I have about 15 years worth) so I can track how a parcel has changed over time. It's interesting to see that the changes seem to be in the same areas or the same parcel.

    We take a snapshot of parcels every October and store the layer as "CertifiedParcels_yyyy" in our master repository. I know we have a parcel history layer similar to what Bj described, but I'm not the keeper of that data. I'll ask my colleague to contribute.

    As Amy mentioned, every year we copy our current published parcels into a separate feature class naming it "Certified Parcel 20xx."  Also, before I make any changes to the geometry of our current published parcels, I copy the polygon (with attributes) to a separate feature class named "Parcel History".  This gives us a reference for changes made within the year.

    I use our "Certified Parcel 20xx" layer more often than I use our "Parcel History" layer.
