Ramsey County Internal GIS Technical User Group

Technical User Group

Technical User GroupTHIS IS YOUR USER GROUP!!For anyone:

New to GISExperienced in GISInterested in finding out more about GIS

We see new users as a valuable additional resource!Improve communicationIncrease effectiveness of GIS county-wide both internally and externally by having an internal working groupIndividuals will benefit on-the-job by using GIS as a toolEncourage collaboration and partnershipsProvide a learning environment:

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

History and Development ofRamsey County GIS

David Claypool, P.L.S.Ramsey County Surveyor

Three Land Surveyors… and one other guy

Ramsey County GIS2 primary goals:

To create a basemap and database that was as accurate as possible To build a GIS collaboratively

It’s all about COLLABORATION!Collaborative efforts will help to ensure your successWe ALL benefit by working togetherSharing knowledge of available data and the process to obtain it is valuable to all of us

CollaborationWhat you could end up looking like if you choose to do GIS on your own!!

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.
