Flashcards in GEOG461W Test 1 Deck (57):
1

what is dynamic representation?

USER and DATA-DRIVEN change

2

define geovisualization

using visualizations of geographic material to facilitate thinking, understanding, and knowledge about aspects of the human and physical environment

3

is geovisualization a process or a product?

it is both the creation of visual representations, thus a process, and the product of those creations.

4

name 5 the five components from which geovisualization rooted?

cartography
visualization in scientific computing
EDA
HCI
information visualization

5

what is geovisualization + computing

turning large sets of data into visualizations to find patterns and support knowledge construction

6

what is geovisual analytics

enabling human analytical reasoning from visualizations

7

name the 4 steps of geovisualization

exploration, confirmation, synthesis, presentation

8

what two things does geovisualization support in visual thinking / private realm

exploring and conformation

9

what two things does geovisualization support in the visual communication / public realm

synthesis and presentation

10

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

11

exploration

examining unknown raw data and creating hypotheses

12

confirmation (analysis)

hypothesis testing and manipulating data in search of answers

13

synthesis

extracting salient patterns and relationships from exploration and confirmation

14

presentation

stage of communicating known information

15

name the three parts of the semiotics triangle

referent, interpretant, and sign vehicle

16

sign vehicle

the actual symbol or text being displayed

17

referent

the actual phenomena being displayed

18

interpretant

The user and the meaning a user attaches to a phenomena relating it to the referent

19

pragmatics

how meaning in created and shared

20

sytactics

how sign vehicles and relations among sign vehicles work

21

semantics

how representations stand for features in the real world

22

name the 4 aspects of apprise

designate, appraise, label, relate

23

name the 4 aspects of stimulate

prescribe, (be) emotive, connote, aesthetic (response)

24

designate

the specify or characterize

25

appraise

to evaluate in an official capacity or to JUDGE

26

label

the attach a label or identify

27

relate

to establish a relationship or interactivity

28

APPRISE

to inform or tell something about

29

STIMULATE

encourage interest or activity in

30

prescribe

to convey rules, laws, or regulations

31

(be) emotive

expressing or prompting emotion

32

connote

to suggest or imply meaning additional to literal meaning (think fat US for fat people)

33

aesthetic

of or concerning the appreciation of beauty

34

what are the 3 parts of spatial dimensionality

point, line, and polygon

35

three ways of mapping time

states - snapshots in time (census)
events - points of change (earthquake)
episodes - sequence of events (hurricane season)

36

what are monmier's two ways of describing time and what is there equivalent

graphic script - play or movie
graphic phrase - scene and act

37

what kind of data is best for dynamic mapping

ordinal

38

name Harrower's 4 challenges in map animation

disappearance, attention, complexity, and confidence

39

name 4 solutions to disappearance

looping
manual stepping
control of pace
symbol decay/benchmarks

40

name 3 solutions to attention

sequencing
voice-over
use of sing vehicles to indicate when things are happening at critical times

41

name 4 solutions to complexity

data filtering
user control
data smoothing
aggregation

42

name a solution to confidence

provided guided tours of tools

43

what is the difference between classical stats and EDA

EDA suggests that you view your stats and visualize them before making any hypotheses

44

what is schneiderman's visual information seeking mantra

generate an overview, zoom, filter data, request details on demand

45

brushing

direct highlighting

46

4 kinds of interacting

brushing, linking, focusing, and arranging

47

linking

cross-view entity connection

48

focusing

change perspective by filtering result in subset view

49

arranging

re positioning the phenomena

50

name 4 space-time exploratory techniques

animation
focusing
map iteration

51

querying

database lookup

52

animation

control of speed, moments, and smoothness

53

focusing

selecting and arranging a subset of information

54

map iteration

creating small multiples

55

name 3 kinds of space-time change

existential, location, and attribute

56

existential change

event appears or disappears for a certain duration or so frequently

57

spatial change

event moves location, height, size, or volume
