GEOG461W Test 1 Flashcards
what is dynamic representation?
USER and DATA-DRIVEN change
define geovisualization
using visualizations of geographic material to facilitate thinking, understanding, and knowledge about aspects of the human and physical environment
is geovisualization a process or a product?
it is both the creation of visual representations, thus a process, and the product of those creations.
name 5 the five components from which geovisualization rooted?
cartography visualization in scientific computing EDA HCI information visualization
what is geovisualization + computing
turning large sets of data into visualizations to find patterns and support knowledge construction
what is geovisual analytics
enabling human analytical reasoning from visualizations
name the 4 steps of geovisualization
exploration, confirmation, synthesis, presentation
what two things does geovisualization support in visual thinking / private realm
exploring and conformation
what two things does geovisualization support in the visual communication / public realm
synthesis and presentation
what is more mimetic and why: isolines representing elevation or a three-dimensional terrain representation?
the model is more mimetic because it is closer to resembling the actual phenomena
exploration
examining unknown raw data and creating hypotheses
confirmation (analysis)
hypothesis testing and manipulating data in search of answers
synthesis
extracting salient patterns and relationships from exploration and confirmation
presentation
stage of communicating known information
name the three parts of the semiotics triangle
referent, interpretant, and sign vehicle
sign vehicle
the actual symbol or text being displayed
referent
the actual phenomena being displayed
interpretant
The user and the meaning a user attaches to a phenomena relating it to the referent
pragmatics
how meaning in created and shared
sytactics
how sign vehicles and relations among sign vehicles work
semantics
how representations stand for features in the real world
name the 4 aspects of apprise
designate, appraise, label, relate
name the 4 aspects of stimulate
prescribe, (be) emotive, connote, aesthetic (response)
designate
the specify or characterize
appraise
to evaluate in an official capacity or to JUDGE
label
the attach a label or identify
relate
to establish a relationship or interactivity
APPRISE
to inform or tell something about
STIMULATE
encourage interest or activity in
prescribe
to convey rules, laws, or regulations
(be) emotive
expressing or prompting emotion
connote
to suggest or imply meaning additional to literal meaning (think fat US for fat people)
aesthetic
of or concerning the appreciation of beauty
what are the 3 parts of spatial dimensionality
point, line, and polygon
three ways of mapping time
states - snapshots in time (census)
events - points of change (earthquake)
episodes - sequence of events (hurricane season)
what are monmier’s two ways of describing time and what is there equivalent
graphic script - play or movie
graphic phrase - scene and act
what kind of data is best for dynamic mapping
ordinal
name Harrower’s 4 challenges in map animation
disappearance, attention, complexity, and confidence
name 4 solutions to disappearance
looping
manual stepping
control of pace
symbol decay/benchmarks
name 3 solutions to attention
sequencing
voice-over
use of sing vehicles to indicate when things are happening at critical times
name 4 solutions to complexity
data filtering
user control
data smoothing
aggregation
name a solution to confidence
provided guided tours of tools
what is the difference between classical stats and EDA
EDA suggests that you view your stats and visualize them before making any hypotheses
what is schneiderman’s visual information seeking mantra
generate an overview, zoom, filter data, request details on demand
brushing
direct highlighting
4 kinds of interacting
brushing, linking, focusing, and arranging
linking
cross-view entity connection
focusing
change perspective by filtering result in subset view
arranging
re positioning the phenomena
name 4 space-time exploratory techniques
querying
animation
focusing
map iteration
querying
database lookup
animation
control of speed, moments, and smoothness
focusing
selecting and arranging a subset of information
map iteration
creating small multiples
name 3 kinds of space-time change
existential, location, and attribute
existential change
event appears or disappears for a certain duration or so frequently
spatial change
event moves location, height, size, or volume
