Great River Energy Corridor Management Project

Transcription

1 Great River Energy Corridor Management Project A subproject of GRE s Enterprise GIS Project Mike Siedschlag GIS Tech II United Services Group/ Great River Energy

2 Topics GRE Transmission Facts Corridor Management Project Scope and Purpose Sub Projects Land Rights Easement Entry Access Points/Barriers County Parcel Acquisition Vegetation Management Questions

3 GRE Transmission Facts 2,500+ MW of generation 4,500+ miles of transmission 35,000+ Structure locations Over 100 substations Serves 600,000 homes, businesses, and farms

4 Scope and Purpose Part of GRE s Enterprise GIS Road Map Integration and/or development of multiple systems and data to support transmission corridor management

5 Land Rights Easement Entry Easement Documents ROWES Program Right Of Way Easement System GIS Easement Feature Splitting Easement Feature Attribute Entry for Easement Feature

6 Land Rights Easement Entry Easement Documents Many cabinets of paper easement documents! 85 drawers of easement docs!

7 Land Rights Easement Entry Easement Documents Scanning Effort Previously scanned and tagged paper easements in Oracle Content Server

8 Land Rights Easement Entry ROWES Program No consistency of old documents Re-entry of easement information into consistent form Capture additional information about easement ie. current owner, removal of restrictions, line name change. Maintains history of changes

9 Land Rights Easement Entry ROWES Program ROWES to be migrated over to web based solution utilizing ArcServer technology Utilize GRE s standard web viewer

10 Land Rights Easement Entry GIS Easement Feature Data Model Easement Feature Necessary fields to relate back to original easement document. GIS Easements Buffer around transmission line feature <69kV : 70ft 115kv : 100ft 230kv : 150ft >400kv : 200ft

11 Land Rights Easement Entry Splitting Easement Feature Acquire easement information Paper documents Oracle Content Server Proper land descriptions Ex. Northeast Quarter of the Southeast Quarter, except the Northerly 80 ft thereof

12 Land Rights Easement Entry Splitting Easement Feature Split Polygons

13 Land Rights Easement Entry Attribute Entry for Easement Feature Required Fields Easement Number Type (Easement/Permit/Agreement/Other) Comments (Condemnation, etc.) Restrictions Y/N Restriction Comments No spray areas, Cut and stack logs, etc. Easement (No Line), DNN s

14 Access Points/Barriers Data Model Features What structures are accessible from this point? From what road or path is the access point? What type of barrier is blocking the route?

15 Access Points/Barriers Existing points/barriers sources: Newly build projects ex. Tower to Embarrass transmission subs Documentation from field crews Suspected access and barriers from Cross-County denoted lines. Important to capture bread-crumb trail of access through cross country areas. Future ties with Veg. Mgmt. System

16 County Parcel Acquisition GRE decided to acquire parcel data from counties where it had transmission assets.

17 County Parcel Acquisition Statistics: 67 MN/WI Counties GRE is assets in Cost 48 Obtained GIS parcel data 15 No GIS data 4 Still trying to get data from 27 of 48 Free or agreed to data sharing agreement Remainder mostly purchased only parcels that intersected 500 buffer of transmission line.

18 County Parcel Acquisition MnGeo Parcel Datamodel GRE worked to merge all acquired parcel data into MnGeo parcel datamodel Difficulties obtaining parcel data Future: Wish there was a parcel feature maintained by the state! MnGeo proposing business plan for Statewide Parcel Integration Survey just closed 3/27/2012 Check out website for more info!

19 Vegetation Management GRE needed a program to manage it s ROW vegetation clearing Explore existing software Build our own Leave As Is

20 Vegetation Management Created possible mapping solution in house. Based on ESRI software. ArcGIS for office use ArcPad for field

21 Vegetation Management 1 st Step Address the needs of GRE Byron Johnson Senior Forester Went through Byron s process Byron s Island Spreadsheets upon spreadsheets! Systematic Process Review undertaken by Vegetation Management Team Team: Veg. Mgmt., TR Assets, GIS, BA

22 Vegetation Management Byron s existing process

23 Vegetation Management

24 Vegetation Management

25 Vegetation Management Veg. Mgmt. Team now had knowledge of current and future processes Sent to the vendors was our data script and sample data Creation of software vendor evaluations Blow by blow of what we expect the software to do Functional and Usability scores Time for vendor demos and evaluations

26 Vegetation Management Existing Software in the market Clearion Software 3-GIS Velco

27 Vegetation Management Clearion Software Market leader in enterprise maintenance management systems Software: Workforce Management In office software for use by GRE to plan, organize, execute and track work orders. Clearion Mobile Mobile software that allows the user to view, edit, and manage vegetation and environmental data in the field.

28 Vegetation Management 3-GIS Software Web based solution that could easily conform to GRE s needs. Software: Network Express Web based GIS for viewing, editing, analyzing, reporting, etc. Field Express Mobile data software for deployment on GPS units Express Conductor Data management software

29 Vegetation Management Velco Software Homegrown G&T solution from Vermont Software: Utilized ArcGIS Server for data management in Office ArcPad on ruggedized tablet computers with GPS and WiFi for field collection All data collected in disconnected environment then sent to the office to compile back into master database.

30 Vegetation Management Decision to go with Clearion Software The best Out of the Box abilities Good data management, reporting, and editing attributed to software Option of purchasing Clearion Mobile or go with ArcGIS Mobile Overall had the most to offer and the resources to help implement at GRE!
