103 ==========================

104 Gdalinfo
|
|
|
105 ==========================
|
|
|
106 **What it does**
|
|
|
107
|
|
|
108 The gdalinfo program lists various information about a GDAL supported raster dataset.
|
|
|
109
|
|
|
110 It will report all of the following (if known):
|
|
|
111
|
|
|
112 - The format driver used to access the file.
|
|
|
113 - Raster size (in pixels and lines).
|
|
|
114 - The coordinate system for the file (in OGC WKT).
|
|
|
115 - The geotransform associated with the file (rotational coefficients are currently not reported).
|
|
|
116 - Corner coordinates in georeferenced, and if possible lat/long based on the full geotransform (but not GCPs).
|
|
|
117 - Ground control points.
|
|
|
118 - File wide (including subdatasets) metadata.
|
|
|
119 - Band data types.
|
|
|
120 - Band color interpretations.
|
|
|
121 - Band block size.
|
|
|
122 - Band descriptions.
|
|
|
123 - Band min/max values (internally known and possibly computed).
|
|
|
124 - Band checksum (if computation asked).
|
|
|
125 - Band NODATA value.
|
|
|
126 - Band overview resolutions available.
|
|
|
127 - Band unit type (i.e.. "meters" or "feet" for elevation bands).
|
|
|
128 - Band pseudo-color tables.
|
|
|
129
|
|
|
130 |
|
|
|
131
|
|
|
132 **How to use it**
|
|
|
133
|
|
|
134 Select from history a suported raster file and choose either Json or Text format for result display.
|
|
|
135
|
|
|
136 An additional option can list available subdatasets.
|
|
|
137
|
|
|
138 |
|
|
|
139
|
|
|
140 **Other options, advanced usage**

|
|
142
|
|
|
143 *-mm*
|
|
|
144
|
|
|
145 Force computation of the actual min/max values for each band in the dataset.

|
|
|
148
|
|
|

|
|
|
150
|
|
|
151 Read and display image statistics. Force computation if no statistics are stored in an image.
|
|
|
152
|
|
|
153 |
|
|
|
154
|
|
|
155 *-approx_stats*
