pub struct DistortionRaster {
    pub lon_min: f64,
    pub lon_max: f64,
    pub lat_min: f64,

Expand description

A distortion-field raster: Tissot parameters on a regular lon/lat grid.

Fields§

§lon_min: f64§lon_max: f64§lat_min: f64§lat_max: f64§ncols: usize§nrows: usize§cells: Vec<TissotCell>

Flattened row-major grid of TissotCell (len = nrows * ncols).

Implementations§

Source§

impl DistortionRaster

Source

pub fn compute( pj: &Pj, lon_min: f64, lat_min: f64, lon_max: f64, lat_max: f64, step_deg: f64, ) -> Self

Compute a distortion raster for the given projection over the given extent.

All lon/lat values are in degrees. The raster has:

  • ncols = ((lon_max - lon_min) / step_deg).ceil() as usize + 1
  • nrows = ((lat_max - lat_min) / step_deg).ceil() as usize + 1
Source

pub fn get(&self, row: usize, col: usize) -> Option<&TissotCell>

Get a cell by row and column index.
