6 gdalmdiminfo - Reports structure and content of a multidimensional
7 dataset

10 gdalmdiminfo [--help-general] [-oo NAME=VALUE]* [-arrayoption NAME=VALUE]*
11 [-detailed] [-nopretty] [-array {array_name}] [-limit {number}]
12 [-stats] <datasetname>
13
15 gdalmdiminfo program lists various information about a GDAL supported
16 multidimensional raster dataset as JSON output. It follows the follow‐
17 ing JSON schema
18 The following command line parameters can appear in any order
20 -detailed
22 Most verbose output. Report attribute data types and array val‐
23 ues.
24 -nopretty
26 Outputs on a single line without any indentation.
27 -array {array_name}
29 Name of the array used to restrict the output to the specified
30 array.
31 -limit {number}
33 Number of values in each dimension that is used to limit the
34 display of array values. By default, unlimited. Only taken into
35 account if used with -detailed.
36 -oo <NAME=VALUE>
38 Dataset open option (format specific). This option may be used
39 several times.
40 -arrayoption <NAME=VALUE>
42 Option passed to GDALGroup::GetMDArrayNames() to filter reported
43 arrays. Such option is format specific. Consult driver documen‐
44 tation. This option may be used several times.
45 -stats Read and display image statistics. Force computation if no sta‐
47 tistics are stored in an image.
48 New in version 3.2.
