VPM Logical Design Summary

Published by City of Washington, DC | District of Columbia | Metadata Last Checked: January 27, 2026 | Last Modified: 2021-12-08T17:02:34.000Z
The Vector Property Geodatabase (VPG), often referred to Real Property Geodatabase (RPG), logical design describes the database design for storage of GIS layers identified in the September 23, 2002, requirements document. The logical design’s goal is to satisfy the identified requirements. The next step is to develop a physical design that implements the geodatabase on a physical platform. This design does not address maintenance issues. The project team has developed a maintenance requirements document that will guide the design enhancements for the purpose of maintenance.
