[-sd subdataset] datasetname
DESCRIPTION
The gdalinfo program lists various information about a GDAL supported raster dataset.
-mm- Force computation of the actual min/max values for each band in the dataset.
-stats- Read and display image statistics. Force computation if no statistics are stored in an image.
-approx_stats- Read and display image statistics. Force computation if no statistics are stored in an image. However, they may be computed based on overviews or a subset of all tiles. Useful if you are in a hurry and don’t want precise stats.
-hist- Report histogram information for all bands.
-nogcp- Suppress ground control points list printing. It may be useful for datasets with huge amount of GCPs, such as L1B AVHRR or HDF4 MODIS which contain thousands of them.
-nomd- Suppress metadata printing. Some datasets may contain a lot of metadata strings.
-nrat- Suppress printing of raster attribute table.
-noct- Suppress printing of color table.
-checksum- Force computation of the checksum for each band in the dataset.
-listmdd- (GDAL >= 1.11) List all metadata domains available for the dataset.
-mdd domain- Report metadata for the specified domain. Starting with GDAL 1.11, ‘all’ can be used to report metadata in all domains
-nofl- (GDAL >= 1.9.0) Only display the first file of the file list.
-sdsubdataset- (GDAL >= 1.9.0) If the input dataset contains several subdatasets read and display a subdataset with specified number (starting from 1). This is an alternative of giving the full subdataset name.
-proj4- (GDAL >= 1.9.0) Report a PROJ.4 string corresponding to the file’s coordinate system.
The gdalinfo will report all of the following (if known):
- •
- The format driver used to access the file.
- •
- Raster size (in pixels and lines).
- •
- The coordinate system for the file (in OGC WKT).
- •
- The geotransform associated with the file (rotational coefficients are currently not reported).
- •
- Corner coordinates in georeferenced, and if possible lat/long based on the full geotransform (but not GCPs).
- •
- Ground control points.
- •
- File wide (including subdatasets) metadata.
- •
- Band data types.
- •
- Band color interpretations.
- •
- Band block size.
- •
- Band descriptions.
- •
- Band min/max values (internally known and possibly computed).
- •
- Band checksum (if computation asked).
- •
- Band NODATA value.
- •
- Band overview resolutions available.
- •
- Band unit type (i.e.. ‘meters’ or ‘feet’ for elevation bands).
- •
- Band pseudo-color tables.
