LBCS: LandBased Classification Standards

LBCSLand-Based Classification Standards

LBCS Project Goals

• Standardize land-use classification
• Recognize existing standards
• Exploit current technologies
• Prepare for change

3
Really, what does it mean?

• Standardize land-use categories
• Across Scales (cities, counties, regions, etc.)
• Across Geography (parcels, traffic zones, etc.)
• Across Purposes (tourist-, college-towns, etc.)
• Update land-use mapping and coloring
• Provide tools for land-use data sharing
• Conversion tools
• Software templates
• Make it as flexible as possible

4
How did we do it?

• Recognized that land uses have multi dimensional
  characteristics
• Uses have physical characteristics
• Uses have functional characteristics
• Uses have structural characteristics
• Uses have development characteristics
• Uses have ownership characteristics
• And several other characteristics . . .

5
Then what?

• Realized that Prof. Guttenberg had developed
• a conceptual framework for classifying land uses
  across multiple characteristics
• a method that will allow multiple ways of coding
  a land use

FOR MORE INFO...

• The Language of Planning by Albert Z. Guttenberg,
  University of Illinois Press, 1993.

6
What else?

• Tied the conceptual framework to database
  technologies so land uses can be shared across
  multiple scales, applications, and jurisdictions
• Devised a model that allows customization without
  breaking the logic of classification

Examples of multi dimensionality

• Residential
• Home occupations? Nursing homes?
• Commercial
• Health Clubs? Hotels?
• Institutional--Military
• Bases, barracks, houses, schools, airports
• Recreational
• Tot-lots to national parks

Specific multi-dimensional examples

• Local government
• Office activities
• Public administration function
• Jails, police stations
• Strip commercial
• Goods sales, services
• Offices, post office
• Storefront church
• Public School
• Classrooms, Playgrounds, Bus garages

Define LBCS

• It is a consistent model
• Classifies land-use characteristics
• Extends the idea of multiple dimensions
• Each dimension has a coding scheme
• Each coding scheme has categories
• Every category has multiple levels
• Allows sharing of data at any level
