Rust Map3d

This is a Rust library for geographic coordinate frame conversion. The implementation is similar to Pymap3d. All the functions are implemented in f64 precision.

No external dependencies

The default units are:

• Radians [rad] for angular variables
• Meters [m] for linear variables
• Greenwich Sidereal Time [GST] for date and time

We support several reference ellipsoids, WGS84 is defined as the default one, obtained with Ellipsoid::default().

List of coordinates systems implemented in the functions:

• Geodetic coordinate system (GEODETIC)
• Earth-Centered Earth-fixed (ECEF)
• Earth-Centered Inertial (ECI)
• Local spherical coordinate system (AER)
• Local tangent plane coordinate system - East-North-Up (ENU)
• Local tangent plane coordinate system - North-East-Down (NED)

Additional functions:

• Radians to Degrees and Degrees to Radians
• UTC time conversion to GST
• 3x3 Matrix - 3x1 column multiplication
• 3x3 Matrix transpose
• f64 round towards zero
• projected distance (Haversine formula) between two coordinates (lat, lon, in decimal degrees)

To-Do List:

• implement functions for right ascension and declination conversions
