What is Typology

1
What is Typology?

• A classification or grouping that is based on
  commonalities with regard to a particular purpose
• Example Ecoregions an ecological
  classification describing, in relatively simple
  terms, the science of why a particular patch of
  land differs from another

2
Landscape Typology at the Watershed Scale

• Categorizing the landscape into relevant types
  reveals the landscape role (function) in natural
  processes and human settlements
• Suitability for particular uses
• Sensitivity to particular phenomenon
• Yields appropriate use and design guidelines (at
  a coarse scale)

Take a small but varied company to any
convenient viewing place overlooking some portion
of the city and countryside and have each, in
turn, describe the landscape We may certainly
agree that we will see many of the same elements
houses, roads, trees, hillsbut such facts take
on meaning only through association they must
be fitted together according to some coherent
body of ideas. Thus we confront the central
problem any landscape is composed not only of
what lies before our eyes but what lies within
our heads.

Your Task

• Propose a typology (grouping) for the Los
  Angeles Watershed / L.A. River
• Should interpret the landscape from a particular
  perspective
• Synthesize at lease 3 factors into a composite
  assessment model that describes the landscape
• Could be based on
• One Analysis Perspective
• Landscape as Ecoregions
• Combined Analyses Perspective
• Landscape as Historical Hydrology
• A Derived Typology
• Landscape as Wal-Mart Site

5
Flow Chart for Your Model

• A recipe for how to execute your model in GIS
• List all data needed (ingredients)
• Proposes how they will be combined to yield
  desired output (map)
• Includes Rules of Combination
• Think criteria and priorities suitability
  modeling SWOT (strengths, weaknesses,
  opportunities and threats)

Your Poster Should

• Include a Descriptive Title
• Provide an Overview of the Project
• Describe and illustrate your model
• Flow Chart
• Rules of Combination
• In-process maps
• Provide background on your factors, as
  appropriate
• Diagrams, maps, illustrations, etc. (perhaps from
  analysis)
• Discuss Implications of your model
• Potential design and planning policies or
  guidelines which may emerge as a result of your
  work.
• Work in PowerPoint or other program of your
  choosing
• Work must be saved as either a PPT or PDF or JPG
  file
• Poster should not exceed 30 x 40 in size.
