Crate dted2

DTED Reader for Rust

Refactor of dted, with updated version of nom, improved functionality, added features, fixes, and optimizations!

Usage

use dted2::{ DTEDData, DTEDMetadata };

let data = DTEDData::read("dted_file.dt2").unwrap();
let metadata: DTEDMetadata = data.metadata;
// or can read just the header without the rest of the data
let metadata: DTEDMetadata = DTEDData::read_header("dted_file.dt2").unwrap();

// query elevation, returns None if out of bounds
let elevation: f64 = data.get_elevation(50.0, 10.0).unwrap();

Description

The dted2 crate is a Rust library designed to parse and handle DTED (Digital Terrain Elevation Data) files. DTED files are a standard format used for storing raster elevation data, particularly for military and simulation applications. The data in DTED files is stored in a matrix of elevation points, representing the terrain’s height above a given datum. This format supports several military and simulation applications including line-of-sight analysis, 3D visualization, and mission planning.

DTED data is organized into three levels of resolution:

• Level 0: Approximately 900 meters between data points.
• Level 1: Approximately 90 meters between data points.
• Level 2: Approximately 30 meters between data points. Each level of DTED provides different details suitable for various precision requirements in applications.

Features

• Data Handling: Efficient handling of large datasets with options to process only required sections of data for memory management.
• Read Functionality: Parse DTED files (.dt0, .dt1, .dt2) into usable data structures. Currently only .dt2 files have been tested. dt1 and dt0 files should in theory work.

TODO

• Geographic Processing: Convert DTED raster data into geographic coordinates based on the WGS84 datum.
• Additional DTED Header parsing: Add support for additional header records. Currently both DSI and ACC records are being worked on, and only the standard UHL header is being read alongside the data.
