gdal-mdim-info - Get information on a multidimensional dataset
Added in version 3.11.
Usage: gdal mdim info [OPTIONS] <INPUT>
Return information on a multidimensional dataset.
Positional arguments:
-i, --dataset, --input <INPUT> Input multidimensional raster dataset [required]
Common Options:
-h, --help Display help message and exit
--json-usage Display usage as JSON document and exit
--config <KEY>=<VALUE> Configuration option [may be repeated]
Options:
--detailed Most verbose output. Report attribute data types and array values.
--array <ARRAY> Name of the array, used to restrict the output to the specified array.
--limit <LIMIT> Number of values in each dimension that is used to limit the display of array values.
--array-option <KEY>=<VALUE> Option passed to GDALGroup::GetMDArrayNames() to filter reported arrays. [may be repeated]
--stats Read and display image statistics.
Advanced Options:
--oo, --open-option <KEY>=<VALUE> Open options [may be repeated]
--if, --input-format <INPUT-FORMAT> Input formats [may be repeated]
gdal mdim info lists various information about a GDAL supported
multidimensional dataset.
The following items will be reported (when known) as JSON:
+o The format driver used to access the file.
+o Hierarchy of groups
+o Group attributes
+o
Arrays:
+o Name
+o Dimension name, sizes, indexing variable
+o Data type
+o Attributes
+o SRS
+o Nodata value
+o Units
+o Statistics (if requested)
The following options are available:
--detailed
Most verbose output. Report attribute data types and array
values.
--array <array_name>
Name of the array used to restrict the output to the specified
array.
NOTE:
Bash completion for --array is possible if the dataset name
is specified before.
--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.
--array-option <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.
NOTE:
Bash completion for --array-option is possible if the
dataset name is specified before.
--stats
Read and display array statistics. Force computation if no
statistics are stored in an array.
--oo, --open-option <NAME>=<VALUE>
Dataset open option (format specific).
May be repeated.
--if, --input-format <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 appropriate 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.
May be repeated.
