摘要
在林业基础调查中,常用1∶10000地理信息图进行实地勾绘定界。这种勘界方法常因调查者判图能力不同,造成不同误差出现。利用GPS测量图,经过坐标和格式转换后,与1∶10000地理信息图叠加比对,可以修正地理信息图判读差错,避免或减少勘界误差出现。
The foundation of forestry investigation,commonly used 1： 10 000 field drew is delimited by geographic information figure,the demarcation method often sentenced to figure for the investigators ability is different,different errors. Using GPS measurement chart,after coordinate and format conversion,and 1： 10 000 geographic information than figure overlay,geographic information can be modified by drawing mistake,avoid or reduce the demarcation of the error.
