Struct GeoGrid 

pub struct GeoGrid {
    pub origin: GeoCoord,
    pub rows: usize,
    pub cols: usize,
    pub cell_width: f64,
    pub cell_height: f64,
    pub rotation: f64,
    pub altitude_mode: AltitudeMode,
}

A georeferenced regular grid anchored to a geographic origin.

Cell (0, 0) is the north-west corner. Row index increases southward, column index increases eastward. All dimensions are in meters.

Fields

origin: GeoCoord

Geographic origin (north-west corner of cell (0, 0)).

rows: usize

Number of rows (south-ward).

cols: usize

Number of columns (east-ward).

cell_width: f64

Cell width in meters (east-west extent per cell).

cell_height: f64

Cell height in meters (north-south extent per cell).

rotation: f64

Grid rotation in radians (clockwise from north). Default 0.0.

altitude_mode: AltitudeMode

Altitude mode for the grid surface.

Implementations

impl GeoGrid

pub fn new( origin: GeoCoord, rows: usize, cols: usize, cell_width: f64, cell_height: f64, ) -> Self

Create a new grid with the given dimensions and cell size.

origin is the north-west corner. cell_width and cell_height are in meters.

pub fn cell_count(&self) -> usize

Total number of cells.

pub fn cell_center(&self, row: usize, col: usize) -> Option<GeoCoord>

Geographic coordinate of the centre of cell (row, col).

Returns None if row >= rows or col >= cols.

pub fn geo_bounds(&self) -> (GeoCoord, GeoCoord)

Geographic bounding box of the grid (north-west, south-east).

pub fn cell_at_geo(&self, coord: &GeoCoord) -> Option<(usize, usize)>

Find the grid cell (row, col) containing a geographic coordinate.

Returns None if the coordinate is outside the grid.

Trait Implementations

impl Clone for GeoGrid

fn clone(&self) -> GeoGrid

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GeoGrid

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

Formats the value using the given formatter.
