GDAL——命令使用专题——gdalinfo命令

 前言

　　GDAL(Geospatial Data Abstraction Library)是一个在X/MIT许可协议下的开源栅格空间数据转换库。它利用抽象数据模型来表达所支持的各种文件格式。它还有一系列命令行工具来进行数据转换和处理。

　　主要针对：ogrinfo命令、gdalinfo命令、gdalsrsinfo命令、gdallocationinfo命令、gdal_translate命令、gdaltransform命令 等。这一节讨论gdalinfo命令。

　　gdalinfo命令主要是查询、操作栅格数据信息。

　　上一篇针对ogrinfo命令做了针对性讲解，见《GDAL——命令使用专题——ogrinfo命令》。

　　软件环境：在安装Mapserver时集成安装。详见《MapServer Configuring with IIS》。
