Abstract: To extract the linear structures from of large data sets, the mathematical model of extracting the linear structures based on weighted total least absolute deviations criterion is proposed, and a new robust linear structures extraction method—BIRCH-WTALD-LGA is presented. It is shows that the method can effectively extract linear structures from large data set with contaminated data by means of computer simulation and application in earthquake distribution data clustering.

Key words: BIRCH algorithm, weighted total least absolute deviations, linear structures
