PLGIS数据采集中特征点位校正及精度分析
Characteristic Point Adjustment and Precision Analysis in Obtaining Data of PLGIS
【摘要】 针对PLGIS数据采集中特征点位存在误差 ,根据GIS空间数据的坐标转换原理 ,提出管线特征点位校正方法 ,并对该方法如何有效提高点位精度进行了数据分析。该方法为管线探测精度的提高和管线管理系统实用性的增强提供了理论依据
【Abstract】 Theories and methods of characteristic point adjusting are discussed by virtue of the coordinate conversion of the spatial data in GIS.Through data analyzing we understand how to effectively improve point precision.This method provides a theoretical basis for improving precision of pipeline detection,and enhances practicability of pipeline management system.
