NAME

       gdalmdiminfo - Reports structure and content of a multidimensional dataset

SYNOPSIS

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

DESCRIPTION

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

       The following command line parameters can appear in any order

       -detailed
              Most verbose output. Report attribute data types and array values.

       -nopretty
              Outputs on a single line without any indentation.

       -array {array_name}
              Name of the array used to restrict the output to the specified array.

       -limit {number}
              Number of values in each dimension that is used  to  limit  the  display  of  array
              values. By default, unlimited. Only taken into account if used with -detailed.

       -oo <NAME=VALUE>
              Dataset open option (format specific).  This option may be used several times.

       -arrayoption <NAME=VALUE>
              Option  passed  to  GDALGroup::GetMDArrayNames()  to  filter  reported arrays. Such
              option is format specific. Consult driver documentation.  This option may  be  used
              several times.

       -stats Read and display image statistics. Force computation if no statistics are stored in
              an image.

              New in version 3.2.

C API

       This utility is also callable from C with GDALMultiDimInfo().
