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
