1 Ramsey County Internal GIS Technical User Group Kickoff March 10, 2004

2 Ramsey County GIS:

3 Introductions Name Department What you are doing and/or hope to do with GIS What do you hope to get out of this User Group?

4 Ramsey County Internal GIS Technical User Group

5 Technical User Group

6 THIS IS YOUR USER GROUP!! For anyone: New to GIS Experienced in GIS Interested in finding out more about GIS We see new users as a valuable additional resource! Improve communication Increase effectiveness of GIS county-wide both internally and externally by having an internal working group Individuals will benefit on-the-job by using GIS as a tool Encourage collaboration and partnerships Provide a learning environment: Hands-On Training Project demonstrations, presentations, etc

7 Technical User Group Presentations for users by users Increase awareness of technical and data resources Encourage discussion Identify data needs Form special-interest workgroups Example: Emergency Preparedness

8 Technical User Group Initially, meetings will be held on a bi-monthly basis…will adjust as needed This is YOUR User Group!! An idea to consider: Split this group into two subgroups: New Users Experienced Users Meet for 1-2 hours First half hour: Entire Technical User Group meets together Second half hour: Subgroups meet to come up with recommendations for the entire group Third half hour: Entire group comes together and discuss recommendations

9 History and Development of Ramsey County GIS David Claypool, P.L.S. Ramsey County Surveyor

10 Three Land Surveyors… and one other guy

11 Ramsey County GIS 2 primary goals: To create a basemap and database that was as accurate as possible To build a GIS collaboratively

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

13 Collaboration What you could end up looking like if you choose to do GIS on your own!!

14 Ramsey County GIS Administrative Group

15 Part of the Ramsey County Surveyor’s Office GIS clients: ANYONE outside of the Administrative Group INCLUDING the Surveyor’s Office! Office is currently located in 910 RCGCW Plans to move to new Public Works facility in Arden Hills later this year

16 Ramsey County GIS Administrative Group GIS Staff: Curt Peterson, GIS Supervisor Carla Coates, GIS Analyst Chris Ulrich, GIS Tech David Wilford, GIS Tech Vacant Primary duty: Maintain the County’s GIS System

17 Ramsey County GIS Administrative Group One of our goals is to help you become successful with GIS We are successful when YOU are successful

18 Time for a break…….

19 Ramsey County’s Base GIS Data Curt Peterson, GIS Supervisor

20 Ramsey County’s Base GIS Data Parcel (property) information Continuously Updated Based on changes received from Records & Revenue Coordinate Geometry (COGO) Includes boundaries, tax information, etc Automated ½ & ¼ Section Map generation

21 Ramsey County’s Base GIS Data Aerial photography Updated on a 3-year rotation Current as of 2003 Color, 6” pixel resolution

22 Ramsey County’s Base GIS Data Physical Features Updated on a 3-year rotation along with aerial photography Current as of 2003 Features digitized from aerial photography Includes: Buildings larger than 80 square feet, road edges, bridges, bodies of water, water towers, above- ground tanks, railroads

23 Ramsey County’s Base GIS Data LiDAR Light Detection and Ranging – points with horizontal (xy) and vertical (z) data Will be used to generate 2’ contours 3-D analysis and modeling Flood modeling Tank farm berm rupture

24 Other GIS Data at Ramsey County Census Political Boundaries Municipal, County Commissioner Districts, Precincts and Wards, St Paul Neighborhoods and Planning Districts, etc… Street networks with address ranges Emergency Management Aerial photography outside of the county And so on…and so on….and so on…

25 Ramsey County’s GIS Fee Schedule In process of updating Data can be purchased Charges for printing and plotting Charges for staff time Custom projects

26 Ramsey County’s GIS Licensing ALL Ramsey County Digital Base GIS Data is licensed! Please become familiar with the conditions of use It cannot be freely distributed to anyone outside of Ramsey County or the Ramsey County GISUG If you have a 3 rd -party working on a project for you Requests for data must go through the GIS Office Contact: David Wilford via or phone ( ) A signed license agreement must be completed before data will be distributed

27 Where we’re going… Curt Peterson, GIS Supervisor

28 Where we are now: Current Data Access Model GIS users must physically move update data to their own desktops or servers Monthly CD updates FTP sites: RCGISUG – Password protected Public – Anonymous login Time consuming Danger of utilizing data that isn’t current

29 Where We’re Going : Enterprise GIS What is an Enterprise GIS System? Centralized data resource Contains both graphical and tabular data

30 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 Café Opportunity for participation among multiple departments. Promotes shared vision, collaboration and development.

31 Phase I RDBMS ArcSDE SAN Public Works Records & Revenue Public Health Human Services County Sheriff County Corrections County Attorney RC GIS Users Group

32 Phase II ArcIMS Svl Eng Data Stg Web Server Met Council Metro GIS Ramsey Cnty GIS Users Grp Other Government Educational Institutions Utility Companies Private Companies County Citizens FTP Srv County Government

33 Phase III RDBMS ArcSDE SAN Public Works Records & Revenue Public Health Human Services County Sheriff County Corrections County Attorney RC GIS Users Group County Fire Wall ArcIMS Svl Eng Data Stg Web Server Met Council Metro GIS Ramsey Cnty GIS Users Grp Other Government Educational Institutions Utility Companies Private Companies County Citizens FTP Srv County Government

34 Enterprise GIS System Allows you to access data directly Allows you to make your data available

35 Where We’re Going Transition from ArcView3 and Arc/Info7 to ArcGIS Migration of data Creation of new applications Building database schemas Data compatibilities And other behind the scene GIS functions… At least a one year project

36 Training Carla Coates, GIS Analyst

37 Training Sessions – Quick Start Designed to get you going For those new to GIS For those transitioning from ArcView 3 to ArcGIS-ArcView 8 Software specific: ArcGIS 8 (ArcView8) Utilize county data Examples based on what you may need to do for your job

38 Training Sessions – Quick Start Designed to supplement other training ESRI – Minneapolis Office (Eagan) ESRI Partners Rowekamp Associates ESRI On-line training modules

39 Training Sessions – Quick Start Limited space (22 learners) STAR Room: 12 network connections 1 for trainer 11 for learners Need 11 laptops with ArcGIS installed 2 people per laptop

40 Training Sessions – Quick Start To maximize effectiveness of training: Using ArcGIS or will be using it soon Access to a machine with ArcGIS Commitment: HOMEWORK Practice exercises Free on-line training modules

41 Demonstration: RCGISUG’s On-Line Mapping Application Carla Coates, GIS Analyst

42 Demonstration: RCGISUG’s On-Line Mapping Application Web address: Project was developed by and is maintained and paid for by the Ramsey County GIS User Group Meetings held the first Thursday of every month Let Carla know if you’d like to be added to their distribution list Presentation by David Windle, City of Roseville and one of the founders of the RCGISUG at upcoming meeting Created with Ramsey County GIS Layers

43 Demonstration: RCGISUG’s On-Line Mapping Application Objective: Provide free user-friendly access to Ramsey County GIS data (and other data sources) to anyone with an internet connection A GREAT way to become familiar with Ramsey County’s ‘Base Data’ HOMEWORK: Noodle around the On-line mapping application and make a map!
