Cards in this deck (17)

1Field Sketches & Photographs+ = Good memory tool - especially with annotations.
- = Only shows one view at one point in time.
2Sketch Maps+ = Good memory tool - especially with annotations.
- = May not be an accurate representation.
3Maps with proportional symbols+ = Good visual representation of data.
- = The scale needs to be right o the symbols fit.
4Flow Line+ = Good to show direction and size of movement.
- = Map lacks precise interpretation unless statistical data is added.
5Chloropleth Maps+ = Visually Effective, you can see clear special patterns.
- = They give the impressions that the density change abruptly at the boundary line of each area but in reality this does not happen.
6Isoline Maps+ = Data can be represented without artificial area boundaries changes occur smoothly.
- = Can be difficult to construct.
7Dot Maps+ = Good visual representation of distributions.
- = Regular spacing of dots is hard to achieve.
8Line Graphs+ = Can compare multiple continuous data sets easily.
- = only to be used with continuous data.
9Long Sections & Cross Sections+ = show views of whole length and segments.
- = either section is more useful when the other is available.
10Bar Graphs+ = Good visual representation of statistical data.
- = use only with discrete data.
11Scattergraphs+ = It will show you a correlation between two data sets.
- = too few data points can produce skewed results.
12Pie Charts+ = They can be used to represent a wide range of statistical data.
- = Smaller segments can be hard to analyse.
13Triangular Graphs+ = The dominant component in each case can be seen.
- = can be difficult to read and construct.
14Kite Diagrams+ = allows you to see how much of one species there is.
- = tricky to construct and analyse accurately.
15Radial Diagrams+ = allow you to display independent variables.
- + can only be used with specific types of data - continuous scale.
16Logarithmic Graph+ = very useful when a large rang of data needs to be presented.
- = can be difficult to construct and analyse.
17Dispersion Graphs+ = useful for making comparisons either between areas of the same location over a period of time.
- = data must be in a form which can be placed along a number line.
