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

  3. 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

  4. Visualization technique apply Geodata/ thematic Visual Variables determine choose Measurement Scales Link to Perception properties

  5. 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

  7. Visual variables

  8. Types of map used • Choroplethmap • Proportional symbol • Dot distribution

  9. Population Density

  10. Population Density

  11. Social data visualization

  12. ANALYTIC MAP

  13. Life Expectancy

  14. Life Expectancy

  15. Gross Domestic Product (GDP)

  16. Gross National Product (GNP)

  17. Literacy

  18. Population Growth Rate

  19. Death Rate

  20. Fertility rate

  21. Population distribution

  22. Choice of wrong visual variable

  23. Choice of wrong visual variable

  24. 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.
