Hands-On TrainingProject demonstrations, presentations, etc
Technical User GroupPresentations for users by usersIncrease awareness of technical and data resourcesEncourage discussionIdentify data needsForm special-interest workgroups
Example: Emergency Preparedness
Technical User GroupInitially, meetings will be held on a bi-monthly basis…will adjust as neededThis is YOUR User Group!!An idea to consider:
Split this group into two subgroups: New Users Experienced Users
Meet for 1-2 hoursFirst half hour: Entire Technical User Group meets togetherSecond half hour: Subgroups meet to come up with recommendations for the entire groupThird half hour: Entire group comes together and discuss recommendations

Where we’re going…
Curt Peterson, GIS Supervisor
Where we are now: Current Data Access Model
GIS users must physically move update data to their own desktops or servers
Monthly CD updatesFTP sites:
RCGISUG – Password protected Public – Anonymous login
Time consumingDanger of utilizing data that isn’t current
Where We’re Going : Enterprise GISWhat is an Enterprise GIS System?
Centralized data resourceContains both graphical and tabular data
Why move to an Enterprise GIS System?
Provides County wide functionality. Simplifies data layer maintenance/updating Serves a wider range of county needs. More efficient data distribution Opportunity to be a direct node on the MetroGIS Data CaféOpportunity for participation among multiple departments. Promotes shared vision, collaboration and development.
