Visualization

• To represent data graphically in the form of maps, diagrams, charts etc.

• To use different tools to make the data and information informative, effective and easy perception of thematic as well as geographic data

• Different cartographic grammars or symbols are used for the effective visualization

Measurement scales

• Nominal– Differ in type eg. land use

• Ordinal– Ranked but have relative values e.g. low, medium , high etc.

• Interval – Ranked using standard scale which operations of addition and

subtraction, eg temp

• Ratio– Ranked along standard scale, operation of multiplication, division,

addition and substraction is possible. E.g. elevation, population etc

6

Perception properties

• Associative– All are perceived being equal

• Selective– All are perceived as being different but forming group

• Ordered– Can be placed in order of magnitude

• Quantitative– Create an impression of amount or quantities

Conclusion

• These all are quantitative phenomena• Relative(population density, literacy rate, fertility

rate etc) and absolute(population) value have been used.

• Used socio-economic data(GDP, GNP, growth rate, birth rate etc) of Asian countries.

• With the choice of suitable variables in the map, socio-economic data can be perceived and understand easily.
