以广西为例,总结了Geoway和ArcGIS在水土保持普查中的应用技巧,具体介绍了地形图几何纠正、划定野外调查单元、等高线矢量化、等高线高程赋值、数据层坐标定义与投影转换、野外调查底图编制、野外调查清绘图配准及地块属性录入等关键技术,实现了Geoway与ArcGIS在广西水土保持普查数据处理中的一体化作业,既保证了数据质量,又提高了工作效率。
Taking Guangxi as an example, this paper summarized the application skills of Geoway and ArcGIS in soil and water conservation census, and introduced the geometric correction of topographic maps, delimited field investigation units, vectorization of contour lines, elevation assignment of contour lines, Projection conversion, mapping of field survey bottom maps, registration of clear field maps in the field investigation and inputting of block attributes, the integrated operation of Geoway and ArcGIS in data processing of soil and water conservation in Guangxi was realized, which not only ensured the data quality but also improved Work efficiency.
