GDALMDIMINFO(1) GDAL GDALMDIMINFO(1) NAME gdalmdiminfo - Reports structure and content of a multidimensional dataset SYNOPSIS gdalmdiminfo [--help] [--help-general] [-oo <NAME>=<VALUE>]... [-arrayoption <NAME>=<VALUE>]... [-detailed] [-nopretty] [-array <array_name>] [-limit <number>] [-stats] [-if <format>]... <datasetname> DESCRIPTION gdalmdiminfo program lists various information about a GDAL supported multidimensional raster dataset as JSON output. It follows the follow- ing JSON schema The following command line parameters can appear in any order --help Show this help message and exit --help-general Gives a brief usage message for the generic GDAL commandline op- tions and exit. -detailed Most verbose output. Report attribute data types and array val- ues. -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 documen- tation. This option may be used several times. -stats Read and display image statistics. Force computation if no sta- tistics are stored in an image. New in version 3.2. -if <format> Format/driver name to be attempted to open the input file(s). It is generally not necessary to specify it, but it can be used to skip automatic driver detection, when it fails to select the ap- propriate driver. This option can be repeated several times to specify several candidate drivers. Note that it does not force those drivers to open the dataset. In particular, some drivers have requirements on file extensions. New in version 3.2. C API This utility is also callable from C with GDALMultiDimInfo().
