GDAL-INFO(1)
💖 GDAL-INFO(1) 💖
okay bestie, welcome to the girlies' guide to gdal-info — it lives in the GDAL manual, and it's about to be your new fave 💅
✨ NAME ✨
gdal-info — get the tea ☕ on a dataset. Like, all the info.
Added in version 3.11. 🎀
It's basically a shortcut, no cap: it acts as a shortcut for gdal raster info or gdal vector info, whichever one matches the vibe of the dataset you handed it 🌸
✨ SYNOPSIS ✨
Usage: gdal info [OPTIONS] <INPUT>
Return information on a dataset (shortcut for 'gdal raster info' or 'gdal vector info').
Positional arguments:
-i, --dataset, --input <INPUT> Input raster, vector or 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:
-f, --of, --format, --output-format <OUTPUT-FORMAT> Output format. OUTPUT-FORMAT=json|text
For all options, run 'gdal raster info --help' or 'gdal vector info --help'🫶 Positional arguments (yes it's required, bestie)
-i,--dataset,--input<INPUT>— the dataset you wanna snoop on. Raster, vector, or multidimensional raster, all welcome here. This one is required, so don't forget it 🙈
🌈 Common Options
-h,--help— pops up the help message and dips out. Classic.--json-usage— shows you the usage as a JSON document, then exits. For the structured-data girlies ✨--config<KEY>=<VALUE>— sets a configuration option. You can repeat this one as many times as you want, go off 👑
💅 Options
-f,--of,--format,--output-format<OUTPUT-FORMAT>— picks the output format. Your choices arejsonortext. That's it, that's the menu 🍓
Heads up: for all the options, rungdal raster info --helporgdal vector info --help— that's where the full list is hiding, iykyk 😭
✨ RETURN STATUS CODE ✨
The program returns status code 0 when it slays, and non-zero when it doesn't 💀 (and lowkey important: non-blocking errors that get emitted as warnings still count as a successful execution, so yeah, that's a 0).
✨ EXAMPLES ✨
🌸 Example 1: Getting information on the file utmsmall.tif (with text output)
$ gdal info utmsmall.tif
Driver: GTiff/GeoTIFF
Files: utmsmall.tif

Band 1 Block=100x81 Type=Byte, ColorInterp=Graylook at all that info, she ATE and left no crumbs 👑
Example 2: Getting information on the file poly.gpkg (with JSON output), listing all features
okay so this one is the FULL meal bestie — we're hitting poly.gpkg with --format=JSON AND --features, which means you get everything: the driver tea, the layer name, the coordinate system in excruciating gorgeous detail, the fields, the feature count, and then the actual features themselves. This is giving "I asked for a summary and got a dissertation" 💅 but it's exactly what you asked for so pop off.

okay bestie we're back and she is still yapping coordinates 😭 this is the part of the JSON output where gdalinfo just… keeps going. no chill. no brevity. only numbers. and honestly? iconic.

},🏁 that's feature one DONE. look at her go.

and then?? she just starts the next one. no pause. no breath. 😭

ngl the way this file just stacks whole polygons on top of each other with zero acknowledgment is giving “I am not a summary, I am a receipt” 💅
