- Abstract
- This data layer contains boundaries for Newton's zip codes. Note that one of those zip codes, for a property at the eastern edge of the city, just above Commonwealth Avenue, is 02435. This is a Brighton zip code. It occurs in Newton because the properties are in Newton but with an address on Undine Rd, which is in Brighton.
- Purpose
- This layer was created primarily for and 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, or to provide a basemap to support graphical overlays and analysis with other spatial data. This layer will provide a basemap for layers related to real property and address or location matching purposes. More advanced user applications may focus on public policy and planning and related purposes (including defining boundaries, managing assets and facilities, integrating attribute databases with geographic features, spatial analysis, and presentation output.)

- Data Quality Information
- 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
- From: PARCELS Datalayer Horizontal Accuracy Report: Points fall within their respective property boundaries. No systematic and quantitative review of property boundary accuracy has ever been conducted. However, several qualitative observations based on experience using the data are possible. The street right-of-way lines overlay the orthophoto base map very well, falling on or close to the apparent back-of-sidewalk visible on the photos.The edge-of-pavement data layer was compiled from aerial photography for Boston Edison to an absolute accuracy specification of +/- 2.5 feet. Again, the right-of-way lines match up well in this comparison. Less is known about the accuracy of the internal property boundaries. Casual observations suggest they are sometimes as accurate as the right-of-way lines and sometimes much less. Some observations of boundary line discrepancies relative to property boundary lines such as fences and hedges visible on the orthophotos indicate that internal property boundaries may be off by at least +/- 5 feet
