Agenda • • • Service Oriented Architecture Case Study Solutions Benefits Questions

Service Oriented Architecture • Loosely-coupled applications and components – Web services – Windows services – Database procedures and processes • Hosted or served in a central environment • Does not care what is consuming it, just as long as it provides the necessary information. • Chaining of services together to get a desired result.

Case Study: City of Indianapolis/Marion County • ISA’s GIS Division Mission Statement – "Delivering professional services and decision support systems through robust and accurate spatial databases, innovative geographic information system applications, and strategic partnerships which support Indianapolis/Marion County government and improve the quality of life for all citizens. " • GIS Division serves over 700 internal customers with 10 staff members, 900, 000 citizens • Since 2003, Woolpert has provided GIS development services • Together, we have performed over 90 projects since then

It all starts with data… • The City had already developed a mature GIS and Master Address Database(MAD)

Our first projects… • Maintaining Data – a set of tools to allow for the editing and maintaining of centerline and address data through the GIS – have those changes reflected back into the MAD

Using GIS Functionality… • Being savvy GIS people, the City realized that GIS could tie a lot of things together – Not only a way to view information spatially… – New ways to query and analyze information

Map based applications • Still, the primary goal was to see the data on a map”… – Intranet Data Viewer – Catalog Interface

Arc. GIS Server • Through Arc. GIS Server, we could then use advanced Arc. Objects functionality via web services – Address Validator – Geocode – Point in Polygon • return specific attributes from those features.

Sharing GIS information • These initial Arc. GIS Server web services provided a new way of sharing and providing the use of GIS data to non-GIS systems and users – Siebel – Tidemark – Hansen • Using GIS as just another tool in the overall enterprise • Provide GIS information through services

Goals – g. IS – little “g”, big “IS”… • Makes GIS Invisible To The Consumer – Modular, Highly Reusable – Standards-based – Cross-platform – Machine to Machine – Adds New Capabilities To Existing Apps/Databases Service Oriented Architecture (SOA)
