The Adams County Parcel Database was derived from a variety of source maps including survey plats, deed descriptions, subdivision plats, certified survey maps and right-of-way plats. All new parcels are entered into the database using coordinate geometry (COGO). Note that the End_Date column is used to identify retired parcels. Current parcels have no End_Date value and can be viewed by setting a definition query like this: SELECT * FROM Parcel WHERE End_Date IS NULL.
