  - Mike Goodchild
    - Al Gore put forward a vision of Virtual Earth in 1992
    - Denver colorado real estate using Google Earth o sell property
    - Google Earth used to visualise Hurricane Catrina
    - Major features of Google Earth
      - Based on web transactions
      - Based on PC hardware graphics cards
      - Based on recursive subdivision
        
        Problem is how to do this for a globe
        
        Jeffrey Dutton's (sp?) scheme
        
        Geofusion came up with a neat solution then used by ESRI
    - Large to small ratio
      - Human eye is 10000
      - log(l/s) is nearly always in the range (3,4)
    - GIS and the flat earth society
      - Proprietary GIS are flat earth
      - Lots of artifacts as a result of this
    - KML
      - API for google earth allows users to add data to google earth
      - Large community now adding data
      - Mapping Hacks - good book written without regard of geographic information specialists
      - What would we ask the meridian convention to standardise today if they were to reconvene
    - Google Earth is bigger than GIS
      - It is the democratisation of GIS
      - How can we get Google to improve the map base?
      - How do we visualise the non-visual?
      - How can we find all the add ons that people have developed?
        
        Need for a registery
    - How to make a cartogram on google earth?
    - How to use the geographic information organisation metaphor to organise files and research?
    - Ethical issues
      - Surveillance
      - Privacy
      - Data usurping
      - RFIB
    - OGC standards
      - Google taking any notice? - No?
      - What about competitors?
    - Spatial Analysis Methods as taught by Mike in the 1960s was more advanced than what he teaches nowadays
    - Need to move to modelling and simulation and for this we should be using WorldWind in MoSeS
    - Nice one Mike !)
  - COFFEE BREAK
    - Spoke with Rich Kingston, Andy Hudson-Smith, Anna Barford from SASI about a 3D globe visualisation of a cartogram
    - Jon Milton showed my a report written by Roger Burrows in York about geoinforamtion effects on neighbourhoods
  - Social Anthropologist
    - Participant observation often changes field they are studying - symbiotic
    - Geographic maps are representations of reality
      - Do not have to be visual
    - Mike Batty talked about complex networks
      - Pajek
        
        Can be used for mapping power relations?
  - Jason Dykes
  - Links in Nottingham talk on Lanscape visualisation
  - Spatial literacy in teaching (Leader: Tate in Leicester)
    - http://www.spatial-literacy.org/
  - LUNCH
  - Revizualising our World
    - Anna Barford
    - http://www.worldmapper.org
    - Code available on the web
      - Java and C
      - Great!
    - Mercator projection preserves angles
    - Peters projection preserves area
    - Making cartograms
      - Mark Newman
      - Regions change by preservingas much as possible their outline, but equalising the density of a variable.
      - Atlantic and polar regions attempted to keep rigid for readabiltiy and comparability between maps
      - I mentioned that linking a maps for highlighting and learning cartograms
  - Aerial Photographs
    - Scott Orford
    - Cardiff
    - Interesting work on dwelling type based on comparing remote sensed data and census data
  - Geovisualisation and time
    - Menno -Jan Kraak
    - Nice time maps - cartogram like change of accessibility
    - Space time cubes - time as the third dimension on 2D spaitial map
  - The Milestones Project: A Case Study in Statistical Historiography
    - Michael Friendly
    - Where are we with Exploratory Visualisation?
    - Multiple linked views and beyond
    - http://www.anc.ed.ac.uk/~amos/publications/MannEtAl2002ScientificDataMiningIntegrationandVisualisation.pdf
  - Geospatial Data Visualisation Via Web Services
    - James Reid EDINA
    - Introduction to OGC
    - NASA Scientific Visualisation Studio
    - GDAS XML
  - BEER
    - Encouraged Anna Barford to contact Danny Dorling with regard collaborating on cartogram visualisation for MoSeS
- 2006-06-13
  - COFFEE
    - Met Michael Wright and encouraged him to contact Bethan Thomas
  - The Visual City
    - Mike and Andy
    - The model city, the ideal city...
    - Need to take care using the term model as it means many different things
    - Great stuff
    - The iconic and symbolic
    - Will Wrights original SimCity was based on a load of entropy maximising spatial interaction models
    - Discusion
      - What to do about Ordnance Survey data restrictions
      - Richard Milton has put Dan Vickers area classifications on google maps
      - Direct Gov site suggest it is easy to report local problmes on local govt websites, but this is not the case
  - 3D GIS: Teaching and planning for the future
    - John Marsdon
    - Useful overview of what students in a town planning course do
      - Demo of sketch up and how to use mastermap data to develop models and design new buildings/gardens etc...
        
        Sketch up is integrated in Google Earth
        
        Extra tools needed from ESRI to export into sketch up
        
        Have a play with this, it looks useful, do we teach our students this in Leeds?
  - Designing Systems for Public Participation in Urban Planning
    - Andy Hamilton and Yun Chen
    - Framework of the methodology is the same as that used in Sustainable Uplands
    - Advocate a stakeholder and user focused approach (not a techology led approach)
      - What is wanted from a system?
      - What technology can support this?
    - http://www.vp.salford.ac.uk/testpage
    - Discusion
      - Community Informatics
      - Ian Beasely Bristol
  - Mobile Phone Data
    - Michael
    - Cool stuff!
    - Is there information about where all mobile phone masts are?
      - It was on someones blog a while ago but was hastily taken down...
  - What do we gain by going to 3D?
    - Work based on Booth's 1889 Poverty Map and associated research
    - 3D is more data dense?
    - Helps with visualising change over time
    - His problem with dots being on top of each other can be best fixed with denisty maps in 2D although the 3D dot plots are another solution. Difficulty with the 3D plots is visualising large amounts of cluttered data (occlusion)
    - Very useful critic of visualisation of data in 3D
    - Highly interative 2D is better than 3D?
    - There is a big difference between visualising reality and visualising data about that
    - Highly interative 2D is better than 3D?
  - Two visualisation communities
    - InfoVis community
      - http://www.msi.umn.edu/user_support/scivis/scivis-list.html
      - These are very different
  - Vision of Britain GBHGIS
    - Humphrey Southall
    - Only deliverable was a web site
    - All data stored as a value in a single database table
    - What where source when meta data for every value

    - Discussion
      - Jason Dykes mentioned Mondrian Software is worth looking at
