The command you provided is using the GDAL (Geospatial Data Abstraction Library) tool called "gdal_translate" to perform a specific operation.
Here's the breakdown of the command:
- "gdal_translate" is the command-line tool that allows you to translate or convert raster data formats.
- "-outsize" is an option in gdal_translate that allows you to specify the output size of the translated image.
- "${40%}" is a bash shell variable representing 40% of the original size. It's used in this command to specify the output size.
- "${path-to-input-tif}" is the path or location of the input Geotiff file. It should be replaced with the actual path to the input file.
- "${path-to-output-tif}" is the desired path or location for the output translated Geotiff file. It should be replaced with the actual path to where you want to save the output file.
So, essentially, this command is using gdal_translate to resize an input Geotiff file to 40% of its original size and save the result as a new Geotiff file.
