Struct SatelliteImage 

pub struct SatelliteImage {
    pub bands: Vec<Vec<f64>>,
    pub band_names: Vec<String>,
}

Multi-spectral satellite image with named bands.

Fields

bands: Vec<Vec<f64>>

Flattened (row-major) pixel values per band.

band_names: Vec<String>

Human-readable names for each band (e.g. "red", "nir").

Implementations

impl SatelliteImage

pub fn new(bands: Vec<Vec<f64>>, band_names: Vec<String>) -> Self

Construct a SatelliteImage from per-band pixel data and band names.

pub fn band_index(&self, name: &str) -> Option<usize>

Return the index of the band with the given name, if present.

pub fn ndvi(&self) -> Vec<f64>

Compute the Normalized Difference Vegetation Index (NDVI).

Requires bands named "nir" and "red". Returns a vector of per-pixel NDVI values in [-1, 1].

pub fn ndwi(&self) -> Vec<f64>

Compute the Normalized Difference Water Index (NDWI).

Requires bands named "green" and "nir". Returns per-pixel values in [-1, 1].

pub fn false_color_composite( &self, r: usize, g: usize, b: usize, ) -> Vec<[f64; 3]>

Produce an RGB false-colour composite by selecting bands r, g, b (0-indexed) and normalising each channel to [0, 1].

Trait Implementations

impl Clone for SatelliteImage

fn clone(&self) -> SatelliteImage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SatelliteImage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
