• Visualization• Visualization technique• Measurement scales• Perception properties• Visual variables• Maps showing socio-economic data

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.
