摘要
图件数字化是目前空间信息系统(SIS)图形数据采集的主要方法之一。通过对大量实验数据的分析,探讨了数字化采集过程中误差产生的原因和分布规律,得出了一些有益的结论,对如何提高数字化采集精度,从而保障SIS的数据质量有一定的借鉴意义。
Based on studying plenty of expermental data, this paper gives detailed analysis to causes for data error during the process of map digitizing, which is one of themain method of data capture to spatial information system (SIS), Some useful advicesare given. These will show us how to increase map digitizing precision and thus the SISdata quality may be assured.
