hypothesis If the thinking process of the designer (student) is not - - PowerPoint PPT Presentation

hypothesis

• If the thinking process of the designer

(student) is not documented, it doesn’t exist.

• Geodesign is not a priori GIS-based.

Casestudy Passchendaele

• research project ‘from remembrance to vision’:

define the most important relic zones testifying the battle of Passchendaele (third battle of Ypres, 1917)

• Collaboration between:
• Flemish Government Heritage Institute (VIOE)
• Community of Zonnebeke-Passchendaele
• University College Ghent
• The tension between spatial development and

protection of the First World War heritage landscape taken as a starting point.

Passchendaele before 1917

Passchendaele after 1917

Visual analysis

• Shut in areas
• Important views were added.
• Image defining, positive or negative elements

were added

Spatial entities: ‘shut-in areas: visual compartments that are relatively isolated from outward sight and can thus be modified without disturbing any regional panoramas’ (Lynch, 1976 p.180).

4 zones

Preparation of the new Community spatial plan: Alternative Futures

• Defining the stakeholder groups: farmers, local government,

Flemish government, ecologists, tourism agencies and heritage experts (museum management, War Graves Commission, UNESCO…).

• Starting hypothesis was to double housing and industry and make

agriculture more sustainable for the period 2030

• Visitor’s infrastructure is ameliorated for the commemoration of

the Battle of Passchendaele in 2017, where a large number of visitors is expected.

• Working fields are: economy, agriculture, mobility, heritage,

ecological network, sustainability and trends: each field is colour coded.

• Designing the different alternatives in a collaborative way, the

teachers assisted in the process on an equal basis.

Teaching undergraduate students

• Knowledge of GIS has to be built…
• However the technique/ principles of

geodesign can be taught.

Two ways of thinking

• vertical thinking: moving straight ahead with the

development of one particular pattern […] In the natural search for alternatives one is looking for the best possible approach

• lateral thinking: ‘The very word ‘lateral’ suggests the

movement sideways to generate alternative patterns. In the lateral search for alternatives one is trying to produce as many alternatives as possible. One is not looking for the best approach but for as many different approaches as possible (De Bono, 1970 pp.58-59).

Generating alternatives

• ‘The process (of generating alternatives) […]

needs to be rooted in what becomes a very systematic process of investigations of options and selection.’ (Lawson& Dorst, 2009 p.199)

• ‘Complex situations need to be framed to

make them workable. The frames are views on the problem, focussing on selected issues as if through a frame that temporarily blanks out

• ther matters.’ (Schön, 1987)

Landscape engine? Example green structures

• 4D-GIS: example planting > visualise and

calculate:

Need for monitored evolution: spontaneous or planted? Soiltype, humidity,… > Production of Renewable energy: coppiced planting: Impact on the view (9-12 years) Benefit for the farmer >< loss of agricultural land Positive impact on erosion- sensitivity (water, wind) Eco-network

• utcomes
• Transparents are used to talk to the people of

the place: no threshold

• Alternative futures used as a teaching

method: documenting the students thinking process, offering them a thinking framework

• We realised with our study a new

‘ankerplaats’ that can become a heritage landscape needed for the status of UNESCO- WH
