Options: Image resolutions

In order to simplify maths, all images are resized to GOES-R 2km or 4km spatial resolution. This corresponds to 5424px square and 2712px square respectively. The Resources\satelites.json file can also specify crop ratios for satellite images which contain borders around the images.

The default output spatial resolution is 4km. This provides the fastest output and minimises upscaling. Note that the underlay provided with Sanchez is at 2km spatial resolution, so only IR imagery is upscaled.

Output resolution is specified using -r / --resolution and valid values are 2 or 4.

Sample usage

sanchez -o output\geostationary -s sample-images -r 2
