| Title | Electric Utility Service Area Boundaries, Minnesota, 2012 (version for PUC review) | |||
| Abstract | This dataset shows electric utility service area boundaries for the State of Minnesota. The original source data were lines hand-drawn on county highway maps. The maps were scanned and georeferenced to serve as a background for on-screen digitizing. The utilities were then given an opportunity to review and correct the boundaries. Service area changes filed with the Public Utilities Commission (eDockets) were also reviewed to update the areas.
This version of the dataset is currently undergoing a 6-week review by the Public Utilities Commission and others, starting mid-September 2012, before it is widely released to the public. | |||
| Purpose | The purpose of the project was to convert existing electric utility service area boundaries from paper to digital format in order to provide a statewide view of the boundaries. Then Public Utility Commission eDocket filings can be used to maintain this dataset. | |||
| Time Period of Content Date | 08/31/2012 | |||

| Section 2 | Data Quality | |||
| Attribute Accuracy | Map attributes were checked after digitizing by visual comparisons with the original printed map. Each utility was given an opportunity to review their information. The MUNICIPAL and MMUA_NAME fields are consistent with the 2010 Minnesota Municipal Utility (MMUA) Directory. Summaries were used to review most major attributes. Since the dataset is still being edited, no multiple fields checks were completed on the boundaries layer.
The field ADJ_UTILITY was added late in the process and is filled in as corrections take place. | |||
| Logical Consistency | Topology rules are noted in the Lineage field of this metadata record. | |||
| Completeness | Completed through utility submissions as of 8/31/12. | |||
| Horizontal Positional Accuracy | Overall it is the same as the county highway maps and base map layers which were originally used to locate boundary lines. The accuracy of the boundary linework hand-drawn on the paper maps is approximately +/- 350 feet. When complicated boundaries were encountered, they were typically simplified by the vendor doing the update.
As boundaries are updated digitally using more detailed and accurate base information, the goal is to achieve an accuracy of +/- 60 feet. The gaps and overlaps in the dataset result from utilities submitting boundary changes individually without verifying them with the adjoining utility. | |||
| Vertical Positional Accuracy | not applicable | |||
| Lineage | Goals and Objectives:
1. Create a consistent, state-wide GIS dataset of EUSA, as vetted by the utilities 2. Achieve a positional accuracy of 1:24,000 (+/- 60 feet) 3. Identify (and eventually resolve) service area boundary issues 4. Create a cost-effective process for tracking and updates 5. Make data easily accessible There were a number of phases in the development of this dataset. ----- 2004 ----- Summary of tasks: Scanned county highway maps, digitized EUSA boundaries and printed updated maps for the Minnesota Department of Commerce (DOC) County highway maps are located at the DOC. On these maps are hand-drawn the electric utility service area boundaries for Minnesota. The map scale is 1:63,360 for counties outside the Twin Cities metropolitan area, and 1:48,000 for counties within the metro area. LMIC (now MnGeo) brought these maps to a vendor to be scanned. Electric service area maps were scanned by Historical Information Gatherers, Inc. of Hopkins, MN. The maps were returned to LMIC along with a DVD of the maps in JPEG (200 and 400 dots-per-inch (DPI)) and TIFF formats. 400 DPI JPEG images were geo-referenced using ArcMap 8.2 software. Electric utility service area boundaries were on-screen digitized using ArcMap 8.2 software. The 400 DPI georeferenced JPEG images were drawn in the background as reference. Municipal, Otter Tail Power (OTP) and Minnesota Power and Light (MPL) polygon areas were coded with the municipal name. The information was in Esri coverage and shapefile format at the end of this step. When boundary lines followed public land survey (PLS), roads, lakeshores or other reference lines, the lines were snapped to the appropriate reference GIS layer: - DNR PLS40: deli.dnr.state.mn.us/metadata/pls_fortypy3.html - Mn/DOT BaseMap layers for roads, railroads, lakes, rivers (and possibly others): www.dot.state.mn.us/tda/basemap/index.html ----- 2005 ----- Summary of tasks: Updated EUSA data, created docket table, printed new maps and developed a prototype website Converted data to personal geodatabase format using ArcGIS 9.1. This was done since the geodatabase format supports COGO (traverse), transactions and versioning. Notes: * Due to the complexity of a geodatabase, only a brief description will follow. * The underlying data was not changed; only the format changed. The geodatabase is composed of two feature data sets and one table: 1. EUSA, 2. PLS and 3. Docket_Table. 1. EUSA feature data set has three components: Boundaries - a feature class of service area boundaries Service_Areas - a feature class of service areas as described in this metadata record. EUSA_Topology - The topology relationship between Boundaries and Service_Areas (see EUSA_Topology Properties below). 2. PLS (Public Land Survey) feature data set contains the 87 feature classes (1 feature class for each of Minnesota's 87 counties) of Department of Natural Resources PLS 40, quarter-quarter section dataset, documented at: deli.dnr.state.mn.us/metadata/pls_fortypy3.html 3. Docket_Table - This table contains the docket information from the original maps which were scanned. EUSA_Topology Properties: Boundaries - Must Be Covered By Boundary Of - Service_Areas Boundaries - Must Not Have Dangles Service_Areas - Must Not Overlap Service_Areas - Must Not Have Gaps ----- 2006 ----- Summary of tasks: Assessed utilities' mapping capabilities Completed a survey of electric utility mapping capabilities: distribution media, printing capabilities, data types and digital map types. The survey was reviewed and materials were prepared for delivery to a test group. The layers were updated by adding missing service area changes through September 1, 2005. The electric service area layers (boundary and area) now tracked transactions (changes to service area) by docket. A dissolve layer was created to display the resulting boundaries. ----- 2007 ----- Summary of tasks: Tested delivery of boundary review materials (GIS, CAD, PDF and paper maps). Packages of review materials (instructions, GIS data and PDF maps) were sent to a sample group of utilities. The feedback was used to improve the packages sent to all of the utilities serving Minnesota. ----- 2008 ----- Summary of tasks: Delivered review materials and inventoried utility service area corrections. Updated the materials based on the feedback from the test group and delivered materials to all the electric utilities. Returned utility corrects where cataloged and then the changes were made to the data. As part of this delivery, utilities were asked to review their boundaries with the adjoining utilities. Then they were to fill out a form stating their status: agree or disagree. If there was a disagreement it was to be highlighted on the map/data and given a disagreement identification number. ----- 2009 ----- Summary of tasks: Adjusted utility service area boundaries, updated mapping products and enhanced website. ----- 2010 ----- Summary of tasks: Adjusted utility service area boundaries and verified boundary status. Adjusted electric utility service areas based on corrections received from the utilities. Created a boundary table which tracked utility agreement/disagreement with an adjoining utility. New corrections were cataloged. Technical assistance was provided to the utilities to help them through the process of submitting their changes. New maps were created and distributed to the utilities. The website was enhanced using the latest software and tools. ----- September 2012 ----- Summary of tasks: Adjusted utility service area boundaries, enhanced website, promoted boundary review and released a review version on the public website. Continue to adjust service areas based on materials received from the utilities. In preparation for the public release, PUC announced that the Commission will make a determination on the boundaries. The website ( www.mngeo.state.mn.us/eusa ) has the ability to link to PUC's eDockets system from the dockets layer (years: 1999-2010) or the docket table (years: 1976-2005). Working from smallest to larger, gaps and overlaps were reviewed for elimination. Errors under the accuracy (+-40 feet) of the data were typically removed and boundaries changed to the corrected boundary. Larger errors were sometimes repaired if no visible structures were affected and the boundaries were in general agreement. The gaps and overlaps were created by utilities correcting boundaries independently. Sometimes these areas are legitimate disagreements but others could be quickly resolved if the utilities reviewed each other's boundaries. | |||
