Description
This project was done in house as part of the Master Address Project. Thorough field checks have been carried out to ensure accuracy. Crosschecks have been made with various departments, including Assessing, Community Development, Elections, Emergency Communications, Inspectional Services, and Public Works. Each address point has attribute information including addresses, unique tax parcel ID and building ID which is useful for many different city departments for their respective systems and tools. Aside from housing and business addresses the following have also been included in this layer:Empty lots for potential addressesParks and open space addressesCall box locations

https://www.cambridgema.gov/GIS/gisdatadictionary/CDD/CDD_LandUse

Description
This data set derives from several sources. The primary source is a data dump from the VISION assessing data system, which provided data up to date as of January 1, 2012, and is supplemented by information from subsequent building permits and Development Logs. (Use codes provided by this system combine aspects of land use, tax status, and condominium status. In an effort to clarify land use type the data has been cleaned and subdivided to break the original use code into several different fields.) The data set has further been supplemented and updated with development information provided by building permits issued by the Inspectional Services Department and from data found in the Development Log publication. Information from these sources is added to the data set periodically. Land use status is up to date as of the Last Modified date.

Differences From “Official” Parcel Layer

The Cambridge GIS system maintains a separate layer of land parcels reflecting up to date subdivision and ownership. The parcel data associated with the Land Use Data set differs from the “official” parcel layer in a number of cases. For that reason this separate parcel layer is provided to work with land use data in a GIS environment. See the Assessing Department’s Parcel layer for the most up-to-date land parcel boundaries.

Description
City of Cambridge, MA, GIS basemap development project encompasses the land area of City of Cambridge with a 200-foot fringe surrounding the area and Charles River shoreline towards Boston. The basemap data was developed at 1" = 40' mapping scale using digital photogrammetric techniques. Planimetric features; both man-made and natural features like vegetation, rivers have been depicted. These features are important to all GIS/mapping applications and publication. A set of data layers such as Buildings, Roads, Rivers, Utility structures, 1 ft interval contours are developed and represented in the geodatabase. The features are labeled and coded in order to represent specific feature class for thematic representation and topology between the features is maintained for an accurate representation at the 1:40 mapping scale for both publication and analysis. The basemap data has been developed using procedures designed to produce data to the National Standard for Spatial Data Accuracy (NSSDA) and is intended for use at 1" = 40 ' mapping scale. Where applicable, the vertical datum is NAVD1988.

Purpose
City of Cambridge 1" - 40' base map layers from an April 12 & April 22, 2018 flyover. Basemap layers created by WSP.
