摘要
基于ArcGIS for Desktop针对林业调查规划过程中小班质心批量获取、地形因子信息批量提取、地质因子信息批量提取和小班四至坐标批量提取等4项技术进行浅析。主要得出以下结论:1)借助ArcGIS for Desktop软件和手持GPS,能够精确高效获取项目区小班中心坐标。2)利用ArcGIS for Desktop软件和DEM、坡度、坡向和土壤等基础数据,能精确高效批量提取项目区小班地形和地质信息。3)将ArcGIS for Desktop现有工具进行完美组合,实现对小班四至坐标的批量获取和标注,并消除不同小班四至坐标点交叉标注问题。这将为林业调查规划提供大量帮助。
Based on ArcGIS, the batch extraction technologies of sublot mass centre, terrain information, geological factors information and four to coordinate of sublot in the forestry survey and planning were initial analysised.The main results showed that： （ 1 ）With the aid of Arcgis software and handheld GPScould get sublot center coordinates accuracy and efficiency. （2）Using Arcgis 10.2 software and the basic data of DEM, slope, slope aspect and soil, the information of terrain and geological could extract accuracy and efficiency. （3）The perfect combination of ArcGIS existing tools could realize the batch extraction and annotation of the sublot, and also could eliminate the cross reference problems of four to coordinate of sublot. These conclusions could provide lots of help for forestry survey and planning.
