2 HISTORY In 1900 the citizens of Shakopee voted to own and operate their electric utility The ownership of the system the past 100 years has been both a wonderful financial and social investment Unlike privately owned utility systems Shakopee Public Utilities Commission (SPUC) invests its profits back into the community 5/19/2008 Planning & Engineering 2

9 HISTORY Cont. Shakopee Public Utilities is governed by a five member commission appointed by the Shakopee City Council The Utilities Commission governs both the electric and water distribution The electric system has no generation and transmission facilities but consist of UG/OH distribution facilities and Street lights. Before opting for a GIS system, SPUC had no maps for operating our electric system First talked to ESRI sometime before 2004 Decided to do Pilot Project in 2005 System-wide project began in mid /19/2008 Planning & Engineering 9

21 DATA MODEL Is a neatly presented entity relationship diagram A model which is the backbone of how the data is stored Is an entity model which describes the inherent structure and relationships of data groups Shows the one-one, one, one-many and many-many relationships in the application between features and/or their attributes 5/19/2008 Planning & Engineering 21

27 DATABASE MANAGEMENT SYSTEM (DBMS) The database resides in the SQL server Receives the end user request Validates, analyzes and decomposes the request Maps the requests logical-to to-physical data components Decomposes the request into several I/O operations Search for, locations, reads and validates the data Ensures data consistency, security and integrity Validates the data for the conditions specified by the request Presents the selected data in the required format 5/19/2008 Planning & Engineering 27

28 Hardware & Software GIS server (hardware) was delivered in July, 2006 Server uses Microsoft SQL and ArcSDE software to store and manage the data Currently (2) ArcMap Editor licenses only used by Engineering Technicians (3) Project Engineer (1) ArcReader software allows read-only access for directors and Utility Manager GPS (hardware) and ArcPad software were purchased in early /19/2008 Shakopee Public Utilities 28

29 Map Production Two types of maps were produced and distributed in October, 2007 Feeder (circuit) Maps display the primary voltage distribution system 400ft/inch Bus plates display the entire distribution system 200ft/inch Format is 11 X 17 size, in (5) ring binders for ease of updating Poster size maps can also be produced 5/19/2008 Shakopee Public Utilities 29

34 UPDATING DATABASE New projects are designed using AutoCAD Data is imported to GIS when the plant is placed in service AutoCAD menu to facilitate transfer to GIS being developed in /19/2008 Planning & Engineering 34

35 WHY DESIGN IN AUTOCAD Most engineering firms design in AutoCAD SPU needs the new background to design our electric distribution facilities The GIS parcels come from Scott County New developments are not in the county database until plot is recorded SPU background parcels are updated yearly from county database 5/19/2008 Planning & Engineering 35

36 DESIGN IN AUTOCAD-TRANSER TRANSER TO GIS AutoCAD background can be transferred to GIS as a new image The background will have no parcel information attached It will not be projected to the Scott County USGS coordinate system 5/19/2008 Planning & Engineering 36

37 TRANSFER THE DISTRIBUTION INFORMATION Each layer has to be transferred separately The distribution layer will transfer with some information Layers must be named the same in both systems Attribute information will not transfer to the database table, it must be manually transferred The transfer of information is becoming more automated 5/19/2008 Planning & Engineering 37

43 A NEW AUTOCAD MENU Will facilitate the transfer of information between AutoCAD and GIS Construction sketches should look the same as GIS maps Standardize the sketches and information between technicians Will provide time saving in the design process 5/19/2008 Planning & Engineering 43

44 FUTURE ENHANCEMENTS Production of Water system database started pilot project completed in October, 2007 Will continue to populate Electric database Provide mobile data terminals to field personnel Create a link from GIS to account information Utilize GIS for outage management and reporting 5/19/2008 Planning & Engineering 44
