结合LAS1．0，从公共文件头区、变长记录区和点集记录区3个方面，对LAS格式的各个版本进行了分析比较，并利用Matlab语言实现对各个版本LAS数据的读取、显示以及激光脚点的三维坐标、回波、强度等信息的提取，为后续LAS格式数据的处理奠定了基础。
결합LAS1．0，종공공문건두구、변장기록구화점집기록구3개방면，대LAS격식적각개판본진행료분석비교，병이용Matlab어언실현대각개판본LAS수거적독취、현시이급격광각점적삼유좌표、회파、강도등신식적제취，위후속LAS격식수거적처리전정료기출。
Combining with the LAS version 1.0, the various versions of the LAS format are analyzed and compared from the aspect of public header block , variable length records and point data .Then the data of various versions of the LAS format is read and displayed and the information of laser point is extracted including three -dimensional coordinate information , echo information , intensity infor-mation and so on by matlab program ,which lays the foundation for follow -up of the LAS format of data processing to some extent .
