  • Qunatification in geography:

    After second world war, the main stress was on formulation of abstract models for application of sophisticated statistical techniques.Quantitative analysis focuses on field studies,generating primary data,utilizing secondary data and applying sampling techniques.It is Anglo american school of thought that replaced ideographic approach by nomothethetic approach as a method of study in geography.Many methods are developed for formulation of models in geography.Methods developed are
    Central values and derivation
    Sampling method
    Coorelation and regression method
    Gravity method
    Nearest neighbour technique

    Then different models are formulated for analysis of spatial structure like CPT,crop combination regions.It is development of Positivism paradigm supported quantitative techniques in geography.
    Advantages:
    Scientific basis to geography
    Systematic and methodological tabulation of data
    reduce multitude of observation to manageable number of factors
    Help in deriving suitable methods,trends ,laws and concepts,

    Disadvantages:

    Many geographers lack required knowledge of mathematics so can lead to erroneous results.

    In modern trend write about GPS and GIS ,REMOTE SENSING DATA ANALYSIS METHODS.
