Enterprise GIS – Utah, MD, PA• Utah – existing GIO, working closely with State CIO• MD – acting GIO, working closely with Governor,

State CIO transition at this time• PA – coordinator and Geospatial Technologies

Office Director, working closely with Governor’s Office and State CIO

Enterprise GT/GIS Relationships in PA • Executive Order assigns IT and Geospatial primacy to

Office of Administration, Office for Information Technology

• Communities of Practice (CoP) – Created 4 IT lines of business

• Environmental

• Health and Human Services

• Public Safety

• General Government Operations

• GTO reviews all geospatial investments > $100K• Starting IT Consolidation

– GT/GIS impacts are unknown

Enterprise GT/GIS Relationships in PA• Governor’s Office supports the Geospatial

Technologies Office• Governor is in 2nd Term - Significant Executive

leadership changes occurring– New Secretary of Administration– New CTO– New CIO coming - State CIO’s last day was last Friday– 4th OHS and PEMA Directors in 4 years– Retirements across the Enterprise– Lost one of our biggest supporters to Arkansas, their gain

• Continue to reestablish geospatial relationships

Enterprise GT/GIS Relationships in PA• Former State CIO is now “Interim CIO” while

nationwide search for a new CIO is conducted• Just finished a year-long CIO review process and

GTO is now institutionalized in Office of Administration– GTO Organization Formed, 5 new staff coming…– Very process and prioritization oriented - SLAs, SOPs,

Change Management, demand and time management

Continuing State SDI Progress• Lots of geospatial progress made in the last 4 years

– PAMAP • Statewide Imagery • Statewide LiDAR

– Governance • State Agency Governance Committees – Policy and Technical• Pending Statewide Geospatial Council Legislation

– Geospatial Standards• PA Geospatial Data Sharing Standards 2.5• GIS Software Standards• Metadata Standards

– Enterprise Architecture• Geospatial Enterprise Server Architecture

Continuing State SDI Progress• Statewide Geospatial Council

– Statewide Geospatial Council legislation introduced– The Administration advocates for the formation of a

statewide geospatial advisory council by Executive Order rather than legislation

• Multi-jurisdictional, representative of Commonwealth stakeholders

• To avoid duplication of existing and successful enterprise programs

• To leverage existing areas of expertise and knowledge• To ensure that the statewide geospatial advisory council goals

align with the goals and priorities of all stakeholders

Enterprise SDI Architecture

• Geospatial Enterprise Server Architecture (GESA) – Sophisticated, fault tolerant, high availability architecture– Serves Governmental organizations– Leverages Commonwealth’s Mission Critical computing

environment– Enterprise Geospatial Database– Geospatial Application Hosting Environment

• Address verification and geocoding web services• Geospatial applications and web services

– Citrix-based ArcGIS License Pool

Geospatial Enterprise Server Architecture (GESA)

• Enterprise Geospatial Database – centralized, most agencies not ready for OGC compatible distributed database services yet– Comprised of data that should be shared– Currently 600+ data assets

• State Agency GIS data• Statewide Imagery Data• Enterprise Data Licenses – TANA, Places2Protect, iMapData• Real-Time Weather (AWS and Meteorlogix)

– New data loaded daily

Geospatial Enterprise Server Architecture (GESA)

• Enterprise Geospatial Application Hosting Environment– Hosts all GTO applications– Hosts several other agency applications– Implements clustering and load balancing strategies for

maximum performance and hardware redundancy

Enterprise SDI Architecture• State Geospatial Clearinghouse (PASDA)

– 10+ years of Commonwealth service - PSU– Public Data Access– Metadata support– Commonwealth’s NSDI/GOS Node– Supporting GTO/PEMA for emergency events in the

Commonwealth– Hardening server architecture to make it high availability– Expanding storage to support 10 Terabytes of PAMAP

Imagery and LiDAR data

State SDI Architecture Evolution• Technology Side… Supported by CIO and IT org

– Disaster Recovery Solution – implement best practices for DR, leverage available resources

– Geospatial Web Services – geoprocessing engines – Federated GIS – distributed county data sources, spatial

ETL, on the fly edge-matching, regional data servers– Geodatabase replication – if agencies concur, their data

in the enterprise geospatial database could automatically update PASDA database to share agency data with the public and refresh data more often

– Base Software Upgrades – painful in a large architecture like GESA, regression testing of all applications, web services, and mapping services – ESRI 9.2, Oracle 10g R2

State SDI Architecture Evolution• Softer side… Improved by working with CIO

– Process maturity – After Action Reports, SOPs, SLAs, etc.

– Institutionalize GT/GIS operations within all IT operations– Standards –

• Database standards – projection, naming conventions• Define and implement GESA application development standards

– avoid performance and maintenance issues – Communications are key to success, lack of

communications will lead to failure– Be ready when the opportunity arises (MD)– Faceless IT/GT – depersonalize the job and

communications– Be ready and open to evolve – the only constant thing in

IT and GT is change

Enterprise GIS Lessons Learned• Straight from the CIO…

– You guys are doing great work, keep it up– Work smarter, not harder– Define processes before offering any new services– Stick to your processes and your prioritization… they will

save you in any situation – Live within your resources (demand management)

• Define a vision and work to implement it• Relationships trump technology (Eric-ism)
