On Evaluation and Design of Classification for Map Content Using Probability Distribution Functions

  • This paper introduces and justifies the evaluation of classification using the normal distribution model which is the most fundamental one in the probability distribution functions.Then it puts forward the design method of classifying map content using the principle of normal distribution.In a concrete example,the author adopted two control areas in the course of design and dealt with the non-equal intervals the way for the equal intervals to make it more widely applicable.Finally taking the x2 distribution function as an example,the author further suggested a designing method of classification using other distribution functions to meet the needs of some special classification needs.
