| 摘 要： | 本文通过对灌区AutoCAD数据转换为ArcView视图数据的研究,提出了数据转换过程中需要注意的方面,并对AutoCAD数据转换前的规范化处理和如何配准到实际的地理坐标进行了详细的讨论。特别是World文件的建立,很少有资料对其进行详述,作者通过研究推导,给出了详细的实例说明。同时,阐述了利用现有地理数据和建立可视化灌区的意义。

| Abstract: | In this paper, some views were put forward about transforming AutoCAD drawing data into ArcView shape data by studying on building visualization of irrigation district, and those aspects how to normalize AutoCAD data and how to convert the drawing coordinates to real -world coordinates were discussed in detail. Especially how to establish world file that has litde useable information for reference was explained and presented with an explicit example. In addition, the significance of making use of spatial data in existence and building visual irrigation district was expounded. |
