Mapping Time Space - the basics

  1. 1. TIME-SPACE MAPPING THE BASICS Jeroen van Schaick – j.vanschaick@tudelft.nl – Room 8.12a Faculty of Architecture
  2. 2. DID YOU EVER DRAW TIME? Faculty of Architecture
  3. 3. TODAY • Some theoretical background • Time-space visualisation techniques: some principles • indicating time in visualisations • activity patterns • isochronic maps • tempographic maps • rhythm maps • Time-space maps: some classics Faculty of Architecture
  4. 4. Visualisation in architecture, urban design and planning is never a goal in itself. Maps are information carriers, communication tools and research tools. (Visual) models are simplifications of reality and can be descriptive, explanatory, explorative, or predictive, regarding existing or probable situations. In architecture, urban design and planning (visual) models are also used to explore, plan and project future situations that may be realised through interventions Faculty of Architecture
  5. 5. NORMALLY in architecture, urban design and spatial planning TIME is thought of - in large quantities (years, decades, centuries) - in terms of transformation - visualised in the form of historic analysis and future plans (as 4th dimension) TIME in terms of the USE of urban space is not the fourth dimension after 3-D space - Time as measure (clock & calendars = time made spatial) - Time as container - Time as system (natural time, social time, cultural time, religious time) In the context of architecture, urban design and spatial planning - Time as distance - Time as moment (e.g. snapshot of an urban situation, the time your work starts…) - Time as amount - Time as rhythm - Time as flow (movement) - Time as history/future (change&transformation!) Faculty of Architecture
  6. 6. TIME is about processes: Cyclical, linear and on multiple scales Problems and challenges for time-space mapping: Freezing time in maps: a spatial model of time Scale errors: time scales do not relate directly to spatial scales Analogies between time and space are not straigthforward Simultaneously showing multiple processes in/as space Faculty of Architecture
  7. 7. Drewe 2004 Faculty of Architecture
  8. 8. ….so far the theory Faculty of Architecture
  9. 9. ….now some techniques Faculty of Architecture
  10. 10. ….basic techniques: general Faculty of Architecture
  11. 11. TIME INDICATORS: 1. Symbols: labels, pictograms, scale and colors (legenda!) 2. Reference: clock time, timeline and/or intuitive time representation 3. Forms: Point-Line-Surface-Volume-Animation 4. Medium: map, map series, 3-D model, interactive media, multimedia/multiview, movie 5. Explicit model of the structure of time in relation to the structure of space: what do you want to show?! Faculty of Architecture
  12. 12. TIME INDICATORS: 1. Symbols: labels, pictograms, scale and colors (legenda!) 2. Reference: clock time, timeline and/or intuitive time representation 3. Forms: Point-Line-Surface-Volume-Animation 4. Medium: map, map series, 3-D model, interactive media, multimedia/multiview, movie 5. Explicit model of the structure of time in relation to the structure of space: what do you want to show?! Beware for ambiguous meanings: e.g. arrow transformation movement Faculty of Architecture
  13. 13. ….basic technique 1 Faculty of Architecture
  14. 14. ACTIVITY PATTERNS 1. Activities of 1 person or 1 household 2. Topological (nodes and lines – activity pattern) 3. Elliptical (activity space) 4. 3-dimensional with time as third dimension A. Additional information in text, symbols or manipulation of lines and/or points B. Space as reference map or as integral part of the activity pattern? C. Potentially overlaps & accumulation of multiple individual activity patterns Faculty of Architecture
  15. 15. POTENTIAL PERCEIVED REALIZED Faculty of Architecture

  20. 20. Parkes & Thrift 1978; after Dagens Nyheter 1976 Faculty of Architecture
  21. 21. ….basic technique 2 Faculty of Architecture
  22. 22. ISOCHRONIC MAPS 1.Isolines: connecting points with the same ‘value’ (e.g. temperature, height, distance in minutes from a point) 2. Projected on a topographic or other geographical map 3. Displaying accessibility to and/or from a place in travel time (be aware of how these travel times are calculated and for what mode of transport!) 4. “Centre of the world” A. Overlaps of mulitple isochronic analyses can show best origin or destination to centre(s) B. Additional possibilities: showing accesibility of number of jobs, potential employees, amenities, etc. within one hour C. Can be used for user-base-analysis for public transport stops, etc. Faculty of Architecture
  23. 23. Influence of urban structure and of transport modes: what can YOU do with multimodal transport chains…….? Offenhuber 2002 Faculty of Architecture
  24. 24. Do not forget travel by foot and bike! Klaasen 2004 Faculty of Architecture
  25. 25. …and what about INaccessibility? - For specific groups - For specific places - With a limited amount of money - What do you miss… e.g. the “food-vacuum” Faculty of Architecture
  26. 26. Individual accessibility Place accessibility VS. Weber 2003 Boer 2003 Faculty of Architecture

  28. 28. ….so far ….next A. some theory C. techniques: B. techniques: tempographic maps (3) indicators rhythm maps (4) activity patterns (1) D. some classics isochronic maps (2) ...and some closing remarks Faculty of Architecture
  29. 29. ….basic technique 3 Faculty of Architecture
  30. 30. TEMPOGRAPHIC MAPS (cartograms) 1. Distortion of geographical distance as temporal distance (distortion of mesh, point position, infrastructure network, urban form, shape of a nation or relative distance experienced) 2. Distortion of temporal distance over time A. From a centre B. Multiple time scales (distance & transformation) C. Tentative, but often simplistic D. The flow of movement is lost in representation Faculty of Architecture
