Struct RasterData 

pub struct RasterData {
    pub data: Vec<Vec<f64>>,
    pub width: usize,
    pub height: usize,
    pub nodata: f64,
}

A 2-D raster grid with an associated no-data sentinel value.

Fields

data: Vec<Vec<f64>>

Row-major 2-D data grid (data[row][col]).

width: usize

Number of columns.

height: usize

Number of rows.

nodata: f64

Sentinel value representing missing / invalid cells.

Implementations

impl RasterData

pub fn new(data: Vec<Vec<f64>>, nodata: f64) -> Self

Construct a new RasterData from a 2-D grid.

pub fn statistics(&self) -> (f64, f64, f64, f64)

Compute (min, max, mean, std_dev) over all valid (non-nodata) cells.

pub fn clip_to_bbox(&self, bbox: [f64; 4]) -> Self

Clip the raster to a bounding box [min_x, min_y, max_x, max_y].

In pixel space this maps x → col and y → row (0-origin).

pub fn resample(&self, factor: f64) -> Self

Resample the raster by factor (e.g. 0.5 = half resolution).

pub fn hillshade(&self, azimuth: f64, elevation: f64) -> Vec<Vec<f64>>

Compute hillshade given sun azimuth and elevation (degrees).

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

Compute slope (degrees) using a 3×3 Sobel kernel.

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

Compute aspect (degrees, 0 = North, clockwise) using a 3×3 Sobel kernel.

Trait Implementations

impl Clone for RasterData

fn clone(&self) -> RasterData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RasterData

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

Formats the value using the given formatter.
