The protected and recreational open space datalayer contains the boundaries of conservation lands and outdoor recreational facilities in Massachusetts. The associated database contains relevant information about each parcel, including ownership, level of protection, public accessibility, assessor’s map and lot numbers, and related legal interests held on the land, including conservation restrictions. Conservation and outdoor recreational facilities owned by federal, state, county, municipal, and nonprofit enterprises are included in this datalayer. Not all lands in this layer are protected in perpetuity, though nearly all have at least some level of protection.Although the initial data collection effort for this data layer has been completed, open space changes continually and this data layer is therefore considered to be under development. Additionally, due to the collaborative nature of this data collection effort, the accuracy and completeness of open space data varies across the state’s municipalities. Attributes, while comprehensive in scope, may be incomplete for many parcels.The OpenSpace layer includes two feature classes:OPENSPACE_POLY - polygons of recreational and conservation lands as described aboveOPENSPACE_ARC - attributed lines that represent boundaries of the polygonsThese feature classes are stored in an ArcSDE feature dataset named OPENSPACE that includes ArcGIS geodatabase topology. OPENSPACE_POLY - The following types of land are included in this datalayer:conservation land- habitat protection with minimal recreation, such as walking trails recreation land- outdoor facilities such as town parks, commons, playing fields, school fields, golf courses, bike paths, scout camps, and fish and game clubs. These may be privately or publicly owned facilities. town forests parkways - green buffers along roads, if they are a recognized conservation resource agricultural land- land protected under an Agricultural Preservation Restriction (APR) and administered by the state Department of Agricultural Resources (DAR, formerly the Dept. of Food and Agriculture (DFA)) aquifer protection land - not zoning overlay districts watershed protection land - not zoning overlay districts cemeteries - if a recognized conservation or recreation resourceforest land -- if designated as a Forest Legacy Area

Abstract

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

This dataset was sourced from the Queensland Department of Natural Resources and Mines in 2012. Information provided by the Department describes the dataset as follows:

This data was originally provided on DVD and contains the converted shapefiles, layer files, raster images and project .mxd files used on the Queensland geology and structural framework map. The maps were done in ArcGIS 9.3.1 and the data stored in file geodatabases, topology created and validated. This provides greater data quality by performing topological validation on the feature's spatial relationships. For the purposes of the DVD, shapefiles were created from the file geodatabases and for MapInfo users MapInfo .tab and .wor files. The shapefiles on the DVD are a revision of the 1975 Queensland geology data, and are both are available for display, query and download on the department's online GIS application.

The Queensland geology map is a digital representation of the distribution or extent of geological units within Queensland. In the GIS, polygons have a range of attributes including unit name, type of unit, age, lithological description, dominant rock type, and an abbreviated symbol for use in labelling the polygons. The lines in this dataset are a digital representation of the position of the boundaries of geological units and other linear features such as faults and folds. The lines are attributed with a description of the type of line represented. Approximately 2000 rock units were grouped into the 250 map units in this data set. The digital data was generalised and simplified from the Department's detailed geological data and was captured at 1:500 000 scale for output at 1:2 000 000 scale.

In the ESRI version, a layer file is provided which presents the units in the colours and patterns used on the printed hard copy map. For Map Info users, a simplified colour palette is provided without patterns. However a georeferenced image of the hard copy map is included and can be displayed as a background in both Arc Map and Map Info.

The geological framework of Queensland is classified by structural or tectonic unit (provinces and basins) in which the rocks formed. These are referred to as basins (or in some cases troughs and depressions) where the original form and structure are still apparent. Provinces (and subprovinces) are generally older basins that have been strongly tectonised and/or metamorphosed so that the original basin extent and form are no longer preserved. Note that intrusive and some related volcanic rocks that overlap these provinces and basins have not been included in this classification. The map was compiled using boundaries modified and generalised from the 1:2 000 000 Queensland Geology map (2012). Outlines of subsurface basins are also shown and these are based on data and published interpretations from petroleum exploration and geophysical surveys (seismic, gravity and magnetics).

For the structural framework dataset, two versions are provided. In QLD_STRUCTURAL_FRAMEWORK, polygons are tagged with the name of the surface structural unit, and names of underlying units are imbedded in a text string in the HIERARCHY field. In QLD_STRUCTURAL_FRAMEWORK_MULTI_POLYS, the data is structured into a series of overlapping, multi-part polygons, one for each structural unit. Two layer files are provided with the ESRI data, one where units are symbolised by name. Because the dataset has been designed for units display in the order of superposition, this layer file assigns colours to the units that occur at the surface with concealed units being left uncoloured. Another layer file symbolises them by the orogen of which they are part. A similar set of palettes has been provided for Map Info.

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.Explore all our data on the Cambridge GIS Data Dictionary.Attributes NameType DetailsDescription Comment type: Stringwidth: 50precision: 0 No comments are populated

The Parcel GIS Layer for tax assessment is a high-resolution geospatial dataset that defines property boundaries and integrates detailed tax-related attributes within a Geographic Information System (GIS) environment. Each parcel is represented as a polygon feature in a vector data format, accurately georeferenced using standardized coordinate systems (e.g., NAD 1983, State Plane or UTM), and maintained through cadastral mapping practices. This layer combines spatial geometry with attribute tables containing critical tax assessment data such as parcel ID (APN), ownership information, legal descriptions, assessed land and improvement values, exemptions, tax district codes, and land use classifications. GIS functionality enables advanced spatial analysis such as proximity, overlay, and buffering to support equitable property valuation, enforcement of zoning and land use regulations, and identification of assessment trends or anomalies. Data is managed within a geodatabase (e.g., ESRI File Geodatabase or Enterprise Geodatabase), supporting topology rules to ensure geometric integrity (no overlaps or gaps), versioning for multi-user editing, and integration with automated assessment systems (CAMA). The Parcel Layer is also designed to interoperate with orthophotos, zoning layers, utility infrastructure, and demographic datasets, allowing tax authorities to perform cross-analysis and generate thematic maps for public communication and policy-making. Updated regularly through field surveys, deed recordings, and aerial imagery interpretation, the Parcel GIS Layer plays a central role in ensuring transparency, efficiency, and accuracy in the property tax assessment process. It provides local governments, assessors, planners, and auditors with a dynamic, queryable spatial framework for managing real estate taxation and supporting data-driven decision-making.
