shapefile

First , create a handful of directories for the various shapefile output format types

首先，为各种shapefile输出格式类型创建一组目录

This is a requirement for Shapefile data .

这是Shapefile数据的要求。

The only other dataset in use is a shapefile representing hole boundaries .

惟一用到的其他数据集是表示圆洞边界的图形文件。

The Web-page thumbnail directory specified on the command line is used to give each node the correct shapefile image .

命令行中指定的Web页面缩略图目录将为每个节点提供正确的shapefile图像。

While creating a point shapefile , when you are prompted to add a polyline shape , add each vertex as an individual point .

在创建一个点shapefile时，若系统提示添加一个多线形状，那么就以单个点添加每个顶点。

The access pattern to read the shapefile is not very favored by CD-ROM drives and , therefore , the whole operation slows down dramatically .

CD-ROM驱动器不是很适合读shapefile文件的访问模式，因此整个操作的速度会急剧降慢。

For the sake of example , interaction with the problems shapefile is demonstrated in C + + by creating a command-line utility to add and list problems .

由于是样例，与问题图形文件的交互通过使用C++创建命令行工具添加并显示问题完成。

While creating a line shapefile , if you are prompted to add a point , a warning is written to standard error indicating that the shape was ignored .

在创建一个线shapefile时，如果系统提示添加一个点，一个警告就会写入到标准错误以表明此形状被忽略。

In the next section , if the cluster and shapefile node that has just been printed is the home node , exit the main loop without writing edge or linkage information .

在第二部分中，如果刚刚打印出来的聚类和shapefile节点是主节点，那么退出主循环并且不要编写边或链接信息。

The data in the table was imported as usual from the shapefile europe / roads . shp , and the inline length was set to2000 .

像平常一样，从shapefile文件europe/roads.shp导入表中的数据，然后将inlinelength设为2000。

The whole procedure is repeated with an inline length of2000 , which is sufficient to cause all geometries in that shapefile to be inlined .

整个过程在inlinelength为2000的情况下再重复一遍，2000这个值足以导致那个shapefile文件中的所有几何图形都以内联方式存储。

The ESRI Shapefile format has one important limitation ; it can only store shapes of a single type ( for example , only lines , only points , or only polygons ) .

ESRIShapefile格式具有一个重要的限制；它只能存储单个类型的形状（比如，只存储线、点或多边形）。

In this article , you build a converter to translate these file formats into the more open ESRI shapefile or keyhole markup language ( KML ) formats .

在本文中，您将构建一个转换器来将这些文件格式转换成更为开放的ESRIshapefile或keyholemarkuplanguage（KML）格式。

The most common vector format by far is the ESRI Shapefile ( see Resources ), which stores only a single shape type ; each file can contain only points or only polygons or only lines .

目前为止，最常用的矢量格式是ESRIShapefile（见参考资料），它只存储一种图形；每个文件只包含点或多边形或线条。
