In this topic, you will learn how to configure the Parcel Value Analysis solution to meet specific needs in your organization.

Organize data

Parcel Value Analysis can be used to analyze parcel, property sales, appeals, and foreclosure information. In many cases, you may have this information in ArcGIS, Computer Assisted Mass Appraisal (CAMA), tax accounting, or billing systems.

Review the layers provided with the solution and determine what source data you want to load. Then, load your existing data into the layers provided with the solution before sharing the maps or applications.

The Tax Parcel layer is repeated in the map several times with different symbology configurations. You will adjust the data ranges for the tax parcel data to match your data.
