52. Visual perception & preference
•Original MIT dissertation
•Why do we like/dislike cities?
•Structures and Activities
•How Carl Steinitz changed my life
55. Premises of CK
Municipalities are the locus of change
Cities = Structures + Activities
Reality = Backlog + Future Change
Space Is the Glue
Middle-out = Top-down + Bottom-up
Government only has 6 tools for
implementation and data collection
56. Premises of CK
Municipalities are the locus of change
Cities = Structures + Activities
Like politics, “all change is local”
Reality = is filtered/allowed by municipalities
Change Backlog + Future Change
Space Is the Glue
with CK:
Middle-out = Top-down information strategies
City departments implement + Bottom-up
Government onlyfarmed-in at a fine grain
Urban information is has 6 tools for
Documentation becomes Information
implementation and data collection
Intra- and Inter-departmental sharing is commonplace
Regional patterns (SDI) emerge upon municipal
foundations
57. Premises of CK
Municipalities are the locus of change
Cities = Structures + Activities
Reality = Backlog stable and permanent
Structures are more + Future Change
Space Is the Glue
Structural change can be captured as it occurs
Activities are more dynamic and fickle
Middle-out = Top-down + Bottom-up
Activities can be frozen in time tools for (snapshots)
Government only has 6 and space
with CK:
implementation and data collection
Information about structures is routinely updated
Activities are “spatialized”
Activities are periodically frozen
58. Premises of CK
Municipalities are the locus of change
Cities = Structures + Activities
Reality = Backlog + Future Change
Spaceis atheof “reality” already out there…
There Is lot Glue
Middle-out = Top-down + Bottom-up
But the amount of information is finite
Government only can be completely captured
with CK the backlog has 6 tools for
implementationrather data collection
Urban change is and slow so, with CK
all Structural change is captured at the source
snapshots of activities are creatively obtained
with CK, municipal information is “farmed” daily
59. Premises of CK
Municipalities are the locus of change
Cities = Structures + Activities
Reality = Backlog + Future Change
Space Is the Glue
Middle-out = Top-down + Bottom-up
within CK:
Government key role in municipal information farming
Space plays a only has 6 tools for
implementation andprimary spatial identifiers
Addresses are no longer
data collection
GIS means Geographic Indexing Systems
Space indexes our datasets
60. Premises of CK
Municipalities are the locus of change
Cities = Structures + Activities
Reality = Backlog + Future Change
Space Is the Glue
Middle-out = Top-down + Bottom-up
Government only has 6structured…
Top-down is rigorous and tools for
implementation an “imposition”collection
… but is received as and data and resisted
Bottom-up is passionate and self-interested…
… but unstructured, unscalable and unsustainable
with CK:
Pure top-down and bottom-up approaches disappear
Middle-out combines the positive traits of both
61. Premises of CK
1. Ownership & Operation
2. Regulation
Municipalities are the locus of change
3. Incentives/Disincentives
Cities = Structures + Activities
4. Education & Information
Reality = Backlog + Future Change
5. Rights
Space Is the Glue
6. Mitigation & Compensation
Middle-out = Top-down + Bottom-up
Government only has 6 tools for
implementation and data collection
with CK:
Municipalities consciously & creatively combine the 6
tools for
Information Farming
Policy/Plan Implementation
