目前,用PC—E500作为电子手簿来记录外业数据有三种方法:用数组存贮,用顺序文件存贮和按绝对地址压缩存贮。但无论采用哪种存贮方法,都无法对数据文件进行必要的编辑工作,这也正是测量工作者最需要的能够在外业记录过程中,随时对所发生的错误进行修改、插入、删除、移动等编辑工作,从而实现内、外业的一体化。为此,我们研制开发了这套雷生电子测量系统。 There are currently three ways to record field data using the PC-E500 as an electronic handbook: storage with arrays, sequential file storage, and absolute address compression storage. However, no matter which storage method is used, the data files can not be edited as necessary. This is exactly what surveying workers most need to be able to modify, insert, delete, Mobile and other editorial work, so as to achieve the integration of domestic and foreign industry. To this end, we have developed this Raytheon electronic measurement system.
