Crate oxigdal_terrain 

Advanced terrain analysis and DEM processing for OxiGDAL.

This crate provides comprehensive terrain analysis capabilities including:

• Derivatives: slope, aspect, curvature, hillshade, TPI, TRI, roughness
• Hydrology: flow direction, flow accumulation, watershed delineation, stream networks
• Visibility: viewshed analysis, line of sight
• Geomorphometry: landform classification, convergence, openness

Features

• derivatives: Terrain derivatives (slope, aspect, etc.)
• hydrology: Hydrological analysis
• visibility: Viewshed and line of sight
• geomorphometry: Landform classification
• parallel: Parallel processing with Rayon

Examples

use oxigdal_terrain::derivatives::{slope_horn, SlopeUnits};
use scirs2_core::prelude::*;

let dem = Array2::from_elem((100, 100), 100.0_f32);
let slope = slope_horn(&dem, 10.0, SlopeUnits::Degrees, None)?;

Performance

Most algorithms support optional parallelization through the parallel feature. For large DEMs, consider using parallel variants for improved performance.
