gdalinfo documentation includes -json flag but using it returns "FAILURE: Unknown option name '-json'"

Question

Reading the documentation for gdalinfo describes the option of formatting the output as JSON.

-json

Display the output in json format.

However, when I use the -json tag it appears not to be implemented.

> gdalinfo -json translated_image_overlay.png
Usage: gdalinfo [--help-general] [-mm] [-stats] [-hist] [-nogcp] [-nomd]
[-norat] [-noct] [-nofl] [-checksum] [-proj4]
[-listmdd] [-mdd domain|all]*
[-sd subdataset] datasetname

FAILURE: Unknown option name '-json'

I have GDAL 1.11.1 installed.

Can someone explain why this is happening?

Answer 1

-json was implemented in GDAL 2.0+. 1.11.1 does not have this feature.

• Josh Taylor: Thanks @Thomas-horner, great answer. Do you(,or someone else,) happen to know where I can download GDAL 2.0+ core and Python bindings for Windows x86_64?
• Thomas: Easiest way is to just download the OSGeo4W network installer. You can install a variety of FOSS4G, including the latest gdal versions. trac.osgeo.org/osgeo4w
• AndreJ: Another source for Windows builds is gisinternals.com/development.php. Just select your processor and a MSVC version. The benefit of gisinternals is that it does not interfere with running QGIS/GDAL versions if you use the zipped versions. Start the SDK shell, and run commands at the console inside.
