MassGIS Datalayer De Facto StandardGeospatialZoning
Massachusetts Office of Geographic Information
| Version: 2.1
Standard specifies zoning (GIS) data for jurisdictions across the state of Massachusetts
Details
  • License: No information
  • About the Publisher: MassGIS is an official state agency in charge of collecting, storing and disseminating geographic data. Their work includes establishing a comprehensive, statewide database of geographic information
  • Updated by Publisher: 5/1/2012
  • Level of Use: This standard is used for every jurisdiction in Massachusetts except Boston (this is the most widespread zoning standard available at the moment)
  • Open License: Yes
  • Transferable to other Jurisdictions: Zoning laws are riddled with localized idiosyncrasies. Therefore devising a standard the would span jurisdictions would be very difficult
  • Stakeholder Participation: Government body has only authority over standard
  • Consensus-based Governance: No mailing list or opportunity to pull requests/file issues on a public forum
  • Extensions: No information
  • Machine Readable: MassGIS stores the data in a statewide ArcSDE layer named ZONING_POLY'
  • Human Readable: Data can be opened in GIS platforms such as ArcGIS and QGIS
  • Requires Real-Time Data: MassGIS has not formal method to handle updates for zoning
  • Metadata: Metadata included in the HTML format

Land Based Classification Standards (LBCS) - OWL2GeospatialZoning
American Planner's Association (APA)
| Version: No information
LBCS standard intends to categorize dimension or urban space and provide information about land use. Standard breaks up classification into Activity, Function, Structure Type, Site Development Character, and Ownership
Details
  • License: No information
  • About the Publisher: American Planner's Association is an urban planning organization
  • Updated by Publisher: 4/1/2001
  • Level of Use: Unsure if any city governments actually apply this standard to their open zoning data
  • Open License: No information
  • Transferable to other Jurisdictions: Coding of LBCS makes it possible to break down the data so it may be aggregated to larger jurisdictions. In addition, the standard organizes the terminology for classifying land use and typically is implements within a relational database of geo-referenced spatial units
  • Stakeholder Participation: APA devised the standard along with six other federal agencies
  • Consensus-based Governance: Standard has no mailing list or forum to offer advice/file issues with publishers
  • Extensions: Format is modular so that data can be shared, reused, and extended
  • Machine Readable: LBCS suggests storing multidimensional land use data in relational databases. The LBCS allows each concept to be modeled off an OWL class. Can establish a hierarchical structure for through the OWL subclass system. However, these schemas are NOT mandatory for LBCS adoption. Data for the standard is intended to be georeferenced
  • Human Readable: Standard utilizes defined vocabularies, semantics, and identifiers to categorize schema. Standard can be used for classifying georeferenced spatial units that are stored in a shapefile
  • Requires Real-Time Data: No information
  • Metadata: The standard moves towards applying the OWL2 ontology language for the Semantic Web. This structural framework applies extensive literature logic that can be manipulated with OWL2 tools

Regional Land Information System (RLIS) DiscoveryGeospatialZoning
Metro Data Resource Center
| Version: 2.9.5
This standard indicates boundaries for zoning
Details
  • License: Open Commons Open Database LIcense and Content License
  • About the Publisher: RLIS is a government body that gathers and publishes geographic data for the Portland metropolitan area
  • Updated by Publisher: 3/17/2015
  • Level of Use: Greater Portland Region, Oregon
  • Open License: Yes
  • Transferable to other Jurisdictions: Zoning laws are riddled with localized idiosyncrasies. As a result, devising a standard that spans jurisdictions has proven to be difficult
  • Stakeholder Participation: Metro regional government is the only contributor to the standard's development
  • Consensus-based Governance: Standard has no mailing list or way to offer advice/file issues with publishers
  • Extensions: No information
  • Machine Readable: Shapefile with attribute data stored in a data table
  • Human Readable: Data can be opened and read in GIS platforms such as ArcGIS and QGIS
  • Requires Real-Time Data: Zoning is updated only when data is received from local city and county jurisdictions - city data override county data (when they overlap)
  • Metadata: Metadata required in XML and HTML formats
