利用FME软件实现库区土地勘界面积的自动量算

Automatic Calculation of Land Surveying Area by Using FME in Reservoir Area

针对目前库区土地勘界面积统计方法的不足,特别是自动化程度不高这一缺点,采用GIS技术对库区土地勘界面积的自动统计方法进行研究。提出了一种基于FME的土地勘界面积统计方法:即利用FME软件的数据转换、空间数据处理、属性数据关联和拓扑检查和修改等功能,设计一个应用程序实现库区土地勘界面积的自动批量量算及统计。最后,以某水库土地勘界面积的量算和统计为例,结果证明该方法是可行的。

In view of the current shortage of land surveying area statistical methods for the reservoir area, especially the shortcoming of low degree of automation, the automatic statistical method by using GIS technology is studied in this paper. A method based on FME is presented：using the data transform function, spatial data processing function, attibute data association function and topology check and repair function of FME, the purpose is to design a program to achieve automatic batch calculation and statistics on the land border area in reservoir area. Finally, taking a reservoir in land sur- veying area calculation and statistics as an example, the results show that the method is feasible.
