The bands of a raster asset.

Fields

nodata: Option<f64>

Pixel values used to identify pixels that are nodata in the band either by the pixel value as a number or nan, inf or -inf (all strings).

The extension specifies that this can be a number or a string, but we just use a f64 with a custom (de)serializer.

TODO write custom (de)serializer.

sampling: Option<Sampling>

One of area or point.

Indicates whether a pixel value should be assumed to represent a sampling over the region of the pixel or a point sample at the center of the pixel.

data_type: Option<DataType>

The data type of the pixels in the band.

bits_per_sample: Option<u64>

The actual number of bits used for this band.

Normally only present when the number of bits is non-standard for the datatype, such as when a 1 bit TIFF is represented as byte.

spatial_resolution: Option<f64>

Average spatial resolution (in meters) of the pixels in the band.

statistics: Option<Statistics>

Statistics of all the pixels in the band.

unit: Option<String>

Unit denomination of the pixel value.

scale: Option<f64>

Multiplicator factor of the pixel value to transform into the value (i.e. translate digital number to reflectance).

offset: Option<f64>

Number to be added to the pixel value (after scaling) to transform into the value (i.e. translate digital number to reflectance).

histogram: Option<Histogram>

Histogram distribution information of the pixels values in the band.

Trait Implementations
