3 Data Processing Department ENTERPRISE GIS MODEL “The goal of an enterprise GIS is to implement interoperable technologies, standards, and methods so that GIS data and services can be used more efficiently and more effectively.” ESRI White Paper, Enterprise GIS in Municipal Governments, “The Enterprise Model of GIS is the highest level of GIS development that provides the maximum benefit to the organization that adopts and achieves it. It is a multi-purpose system that is part of the operational framework of an organization. It is based on large-scale GIS data, including parcels and other land- related data. It supports a wide range of applications across the entire organization.” Tomaselli, The Enterprise Model of GIS,and the Implications for People and Organizations The evolution of data management in large organizations typically follows a “punctuated equilibrium” model (Gould and Eldredge 1977), in which the status quo limits the growth or change until the system is disturbed and then rapid change occurs, followed by a new status quo. Such a disturbance may come in the form of a natural or man-made disaster, during which urgency demands action, the limitations of the existing system are exposed, and neces­sity opens the door for change. Keating, et.al., Challenges for Enterprise GIS

5 Data Processing Department ENTERPRISE GIS CHARACTERISTICS Maximize utilization of GIS capabilities Channel timely and accurate spatial and non-spatial data from various sources Provide access to GIS capabilities and data across the organization or enterprise (domain of organizational activity) Share data, avoid redundancy, duplication of effort Avoid confusion Make better decisions with the latest and best data available Implement interoperable technologies, standards, and methods Multi-purpose system that is part of the operational framework of an organization Based on but not limited to large-scale data Necessity occasionally opens the door for change

6 Data Processing Department ST. CLAIR COUNTY ENTERPRISE GIS Short-term goals Establish an authoritative base map of St. Clair County Develop a database structure to support data stewardship Improve business processes for maintaining and increasing the quality of spatial and attribute data Provide support for power and occasional data users Extend access to the authoritative base map  Municipal governments  Taxing districts Longer-term goals Extend access to the commercial sector Share data in a multi-user and multi-versioning environment

23 Data Processing Department ORGANIZATIONAL DEVELOPMENT

24 Data Processing Department SUMMARY Tomaselli’s Enterprise GIS Goals Top Management Leadership (a team of Champions)  Moving away from reliance on contractors  Moving toward discrete project contractor support An extensive, accurate and available GIS database, typically containing parcels and centerlines.  Reengineering enterprise geodatabase design and workflow A skilled core group of GIS staff  One guy (could use another) Adequate centralized, as well as distributed GIS hardware and software.  Terminal Server and Direct Network Connections Active and knowledgeable GIS users and developers in the participating departments and jurisdictions.  DP supports GIS staff development with training seminars Standards, guidelines and procedures for the users to follow.  Database development using the SDSFIE Assigned roles and responsibilities for maintaining the data, with no duplication of effort.  Enterprise geodatabase versioning is in early stages of development
