Objective
•Near-real time Geospatial updates of critical infrastructure and address layers by
• consolidating disparate data sets
• facilitating the consumption of these layers into E-911 mapping system and the state GIS program
Solution
Database replication • Provide seamless,
instant updates
• City
• County
• VITA
• Other Localities
• Thru VITA

Solution
Geoprocessing Tasks• Evaluate data
• Integrate data
• Output E-911 updates
• SHP
• GDB
HRECC
Lessons Learned•Insure robust infrastructure (network and servers)
•Define/refine security issues early
•Coordinate changes to data model
• No longer islands of excellence!
•Basic GIS admin knowledge important
•White paper available
Solution
•ESRI Replication
• Best practice for data sharing
• 1 way replication
• Hands off process once implemented
• Updates Only
•Data provision thru Geodata services

Objective
•Streamline the process of sharing data between localities to support E 9-1-1 mapping and GIS operations Needs
Project status
•Internal replication to staging DB
• Geodata services are published from staging
• Subset focused on PSAP needs
•Geodata services
• Are setup (Bedford, Appomattox, Campbell) , Lynchburg pending
Campbell Regional
• Each local is pulling from surrounding county geodata services
• Other local data replicas are on staging DB
• ETL process (GP tools) used to consolidate and export data and format for E-911
NoVA RRCL
Objective
•Develop a standard regional routable centerline (RRCL) data model and data set usable by computer aided dispatch (CAD) systems throughout the region
• Incorporated into the Virginia Geographic Information Network (VGIN) State road centerline file format (RCL)
• Provide a framework of exchanging routable centerline data in the future
Solution
•Develop regional data model
•Migrate to regional model
•Extensive use of ESRI
• PLTS – Data mgt & QA/QC
• GP Tools – automate QA/QC
•Use ESRI Replication
• Data exchange in the future
