- InfoVis often uses map/spatial metaphors for exploring non-geographic
information. How can we use
existing cartographic methods to improve upon our methods?
- graphic complexity / generalizations
- feature labeling
- map projections
- map design

- First Law of Geography
- Representations of:

- graphic complexity
- choice of label positions
- choice of label terms

- + Useful overview
- + Good contributions to InfoVis
- - Reaching, at times. Some of his
contributions have already been acknowledged in InfoVis
- - Severe lack of details in places, with a "paper-pointer"
inserted instead
|
10
|
- Discusses how current work in geographic visualization has extended
and critiqued Bertin's work, expecially "graphic variables."
- Also outlines 3 specific geovisualization challenges for the next
decade.
|
11
|
- location
- size
- value
- texture/grain
- color
- orientation
- shape
|
12
|
|
13
|
- location
- size
- value
- texture/grain
- color ===>elevation
- orientation
- shape
- Resistance, friction, kinesthetic location?
|
14
|
- Size è loudness, duration
- Value è pitch &
register
- Shape è timbre
- Location è position (in
time)
- Texture è order
- Rate of change & attack/decay
- Frequency
- synchronization
|
15
|
- Geovis uses visual geospatial displays to:
- Explore data
- Generate hypotheses
- Develop problem solutions
- Construct knowledge
|
16
|
|
17
|
|
18
|
- Developing a typology of operations for georepresentations and a
syntactics for their use
- Balancing abstraction and realism in GeoVirtual environments
- Facilitating different-place collaboration
|

|
- + Nice commentary on Bertin
- + Extensions useful and shed more light on rare Bertin book
- - Quite self-referential, without explanations
- - Points reader to systems that use principles, but doesn't discuss
|
20
|
- Research was aimed to understand the cognitive aspects of map use in
the context of health data analysis, and develop visual analysis tools
that integrate principles from cartography, GIS and EDA.
|
21
|
- Construct knowledge
- Using maps and other representation forms
- Dynamically link the visual map display with
- underlying geographic data structures and
- the system users (resulting in maps that change in response to changes
in data and/or to actions on the part of users)
|
22
|
- Map Animation
- Multivariate Representation
- Interactivity
|
23
|
|
24
|
- Goal: Enhance ability of health/statistics specialists to recognize (and
draw inferences about) mortality rate patterns, risk factor patterns,
relations between risk factors and mortality, and change in both
mortality and risk factors (and their relations) over time.
- - spatial pattern analysis
- - spatiotemporal analysis
|
25
|
|
26
|
- + lots of different tasks
- + appropriate conclusions
- - vis for examining results a little confusing
|
27
|
- Demonstrates usefulness of geovis and
- How alternative graphic representations can stimulate the visual thought
process.

- Better able to represent time
- See web site www.itc.nl/personal/kraak/1812

|
33
|
- + Nice array of techniques presented
- -Too little discussion of techniques’ advantages/disadvantages
- -Makes same assertions as MacEachren without evidence
|
34
|
- Defines the function of the map in WebGIS
- Traditional
- Search engine
- Index
- Interface to other geographic and non-geographic info on the Web

- + Survey points out really cool things
- Surveys without saying much
- Plagiarizes himself from last paper (for no good reason)
