- Abstract
- This data layer contains point locations representing Boston Edison's (now known as NSTAR) utility poles throughout the City of Newton.
- Purpose
- This layer is intended for researchers, students, and policy makers for reference and mapping purposes, and may be used for basic applications such as viewing, querying, and map output production. This layer will provide a basemap for layers related to urban planning or to support graphical overlays and analysis with other spatial data. More advanced user applications may focus on urban planning, public works, or utilities purposes, including defining boundaries, managing assets and facilities, integrating attribute databases with geographic features, spatial analysis, and presentation output.
- Supplemental Information
- The City of Newton is not maintaining this layer.

- Data Quality Information
- Attribute Accuracy Report
- The RID, STR_TYPE, and CAPTURE attributes were provided by BECo. and are undefined.
- Logical Consistency Report
- For layers containing line or polygon features, Newton's data layers are "topologically clean". This was verified with Arc/Info software version 7.x in 1998 and is an ongoing part of data maintenance for the relevant data layers.
- Horizontal Positional Accuracy Report
- All of the data provided to Newton by BECo. were captured photogrammetrically from aerial photography taken in the spring of 1991. The contract specifications were for producing maps at 1" = 100' with a horizontal accuracy of +/- 2.5'. The photo negatives approximate scale was 1" = 600'. The photography's survey control specifications were for Second Order Class II or better --state plane feet; NAD83 for horizontal control.
