DtedTerrain

Struct DtedTerrain 

Source
pub struct DtedTerrain { /* private fields */ }
Expand description

Lazy DTED terrain reader backed by raw .dt2 tile bytes.

Heights returned by this reader are orthometric metres, H, above the EGM96 mean sea level geoid used by DTED/SRTM terrain products. They are not ellipsoidal heights above the WGS84 reference ellipsoid.

Implementations§

Source§

impl DtedTerrain

Source

pub fn new(root: impl Into<PathBuf>) -> Self

Build a terrain reader rooted at a directory containing DTED .dt2 tiles, either directly or under the repository’s block directories.

Source

pub fn height_m(&mut self, longitude_deg: f64, latitude_deg: f64) -> Result<f64>

Return the bilinearly interpolated orthometric height H in metres at a longitude-first geodetic position in degrees.

Source

pub fn height_m_with_options( &mut self, longitude_deg: f64, latitude_deg: f64, options: DtedLookupOptions, ) -> Result<f64>

Return the orthometric height H in metres at a longitude-first geodetic position in degrees using explicit lookup options.

Source

pub fn height_batch( &mut self, points: &[(f64, f64)], options: DtedLookupOptions, ) -> Vec<Result<f64>>

Evaluate (longitude_deg, latitude_deg) points in order using one mutable borrow of the resident tile cache.

The tuple order is intentionally longitude-first, matching Self::height_m_with_options, even though geoid batch helpers use latitude-first points.
