Version 2.0, Released October 2007

Overview

Many cities and towns are aware that plans submitted for development review are usually produced using CADD software. Many communities now require, or are planning to require, that copies of the CADD files from which plans are printed be provided to them. The motivation for this requirement is facilitating maintenance of map features and other information commonly found in municipal GIS databases (e.g., parcel boundaries, pipe infrastructure, building outlines, etc.). All benefit when GIS data are better maintained. Rather than having each community develop its own unique requirements for digital plan submittals, it makes sense to have a state-level standard. Therefore, in creating this standard, MassGIS has two purposes:

    1. Enabling municipalities to avoid the time consuming process of developing their own digital submission standard and to avoid the risk of creating a standard that is flawed because they lack sufficient expertise in the issues involved.
    2. Enabling those in the surveying and civil engineering communities to standardize their work processes, if this standard is being used. To the extent that communities implement this standard, standardized requirements for digital plan submittals will save time and money.

Many people reviewed and contributed to developing this standard. They included many representatives from the surveying and engineering community, through the Massachusetts Association of Land Surveyors and Civil Engineers (MALSCE). In addition, reviewers and contributors included municipal GIS staff, regional planning agency GIS staff, and staff from GIS consultants.

Please note that in implementing this standard municipalities will be obtaining a digital version of boundaries and locations. However, MassGIS reminds anyone implementing this standard that, regardless of the sources of the information they include in their GIS databases, the authoritative determination of boundary or other physical locations remains the purview of the professional land surveyor. Obtaining data from a municipal GIS database is not a substitute for the work of a professional land surveyor.
