Practical Work in Geography Class 12 Representation of Data
What is representation of data in geography practical class 12?
The transformation of data through visual methods like graphs, diagrams, maps and charts is called representation of data. Such a form of the presentation of data makes it easy to understand the patterns of population growth, distribution and the density, sex ratio, age–sex composition, occupational structure, etc.
How do you represent data in geography?
We can represent data in Geography with the help of:
- Line graphs – simple and comparative line graph ( simple line graph only for N level)
- Bar graphs – simple and comparative bar graph (simple bar graph only for N level)
- Bi-polar graphs.
- Pie charts.
- Scattergraphs with lines of best fit.
- Climographs.
- Flow line and Desire line graphs.
What is the need of data Class 12 geography practical?
Data related to the total population, density, number of migrants, occupation of people, their salaries, industries, means of transportation and communication is needed to study the growth of a city.
What are the methods of geographic data representation?
Two methods of representing geographic data in digital form are raster and vector. In principle, both can be used to code fields and discrete objects, but in practice there is a strong association between raster and fields and between vector and discrete objects.
What are the two kinds of geographic representation?
A geographic field can be represented by means of a tessellation, a TIN or a vector representation. The choice between them is determined by the requirements of the application in mind. It is more common to use tessellations, notably rasters, for field representation, but vector representations are in use too.
