摘要
目前,大多数GIS软件均能实现矢量数据和栅格数据的裁剪,但集标准图框生成及可定制的批量裁剪为一体的软件则较少。据此,文章通过研究矩形图框、梯形图框的计算方法以及高斯投影正、反算法,在VC6.0中使用C++及开源GDAL库实现了各种比例尺标准图框的批量生成,并可根据用户的各类需求实现矢量数据(.shp格式)和栅格数据(.tif/.img/.pix格式)的批量裁剪,从而实现了GIS数据裁剪的高效性及可扩展性。
At present, most GIS software can realize the clipping of the vector and raster data, but there has been lesssoftwares which conbines the generation of standard frame and customizable batch clipping. And than this paper studiesthe calculation method of rectangular frame and a ladder frame, and Gauss projection positive and negative algorithm, usingof C ＋ ＋ and the open source GDAL library in VC6.0 to generate the various scale standard frame,and can realizethe batch clipping of the vector data（. shp format） and raster data（. tif/. img/. pix format） according to the needs of users,so as to achieve the clipping efficiency and scalability of GIS data.
