MetroGIS Address Point Repository Synchronization Pilot Developed by Carver County
By Peter Henschel, GIS Supervisor, Carver County
Many organizations have a business need for creating and maintaining address point data. With so many organizations needing address data, would a regional address dataset be a viable solution for the MetroGIS community? In March 2004, MetroGIS created an Address Workgroup to bring together city, county and regional organizations who share this same interest in creating address point data.
The Address Workgroup created a vision document to help the GIS community understand how a regional address point dataset could exist through cooperation, data sharing and data collection. A key component to the success of the regional dataset is a mechanism for the address data repositories to synchronize their data with the regional dataset. Once the synchronization process is set up within an organization, the data updates to the regional repository can be scheduled at any time interval, automating the data uploading process. After the data are synchronized, organizations within MetroGIS can access address data across jurisdictional boundaries knowing they are using data maintained by the address authority.
Through a MetroGIS-funded project, Carver County created a methodology for how address point data could be synchronized through a set of tools to allow counties and cities to upload their address point data to a regional dataset. The synchronization process takes the changes from an address point feature class, standardizes the records to conform to an XML schema that meets the MetroGIS Address Point Specifications, and loads them onto a regional FTP server. A service on the Regional Address Point Repository server will scan the FTP location for files, validate the schema of the file, import the data to the repository, and send an email confirmation.
