Shapefile

Shapefile:一种常见的地理信息系统(GIS)矢量数据格式,用来存储地理要素(如点、线、面)及其属性信息。通常由多个同名不同扩展名的文件共同组成(如 .shp、.shx、.dbf 等)。

发音 Pronunciation (IPA)

/epfal/

例句 Examples

I exported the roads layer as a shapefile.
我把道路图层导出为一个 shapefile。

Because the shapefile format stores geometry and attributes in separate companion files, you must keep all the associated files together when you share the dataset.
由于 shapefile 格式把几何信息与属性信息分散存放在配套文件中,分享数据集时必须把所有相关文件一起保留。

词源 Etymology

shapefile 是由 shape(形状)+ file(文件) 组合而来,意指“存储地理形状的文件”。它在 GIS 领域中常用来指代 ESRI 推广的一种经典矢量数据交换格式,因此名字强调“几何形状”的存储。
