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.
50 -if <format>
53 Format/driver name to be attempted to open the input file(s). It
54 is generally not necessary to specify it, but it can be used to
55 skip automatic driver detection, when it fails to select the ap‐
56 propriate driver. This option can be repeated several times to
57 specify several candidate drivers.
58 New in version 3.2.
