摘要
随着城市地理信息系统的计算机管理的普及,繁杂的地理信息的输入量增大,提高地理信息的输入效率成为需要解决的问题。根据工作实际,将图信息作为“图元”和“图块”数据,以减少存储空间,节约输入时间,提高工作效率。
With popularization of GIS for city management volume of data input increases rapidly. It is urgently needed to improve the input efficiency. According to my practice information can be treated as picxels or figure modules in order to reduce storage space and inputting time and improve the efficiency.
