gdalmdiminfo

3.1 新版功能.

报告多维数据集的结构和内容。

简介

gdalmdiminfo [--help-general] [-oo NAME=VALUE]* [-arrayoption NAME=VALUE]*
             [-detailed] [-nopretty] [-array {array_name}] [-limit {number}]
             [-stats] <datasetname>

描述

gdalmdiminfo program lists various information about a GDAL supported multidimensional raster dataset as JSON output. It follows the following JSON schema

以下命令行参数可以按任意顺序显示

-detailed

最详细的输出。报表属性数据类型和数组值。

-nopretty

在没有任何缩进的单行上输出。

-array {array_name}

用于将输出限制为指定数组的数组的名称。

-limit {number}

用于限制数组值显示的每个维度中的值数。默认情况下，无限制。仅在与-detailed一起使用时考虑。

-oo <NAME=VALUE>

数据集打开选项（特定于格式）。此选项可以多次使用。

-arrayoption <NAME=VALUE>

传递给的选项 GDALGroup::GetMDArrayNames() 筛选报告的数组。这样的选项是特定于格式的。查阅驾驶员文档。此选项可以多次使用。

-stats

读取并显示图像统计信息。如果图像中没有存储统计信息，则强制计算。

3.2 新版功能.

计算机辅助编程接口

此实用程序也可以通过 GDALMultiDimInfo() .
