Convert Latitude and Longitude to point in 3D space in python

Convert Latitude and Longitude to point in 3D space in python

To convert latitude and longitude coordinates to a point in 3D space, you can use the Haversine formula to calculate the position of the point on the Earth's surface and then map it to a 3D Cartesian coordinate system. Here's a Python code snippet to perform this conversion:

import math def lat_lon_to_xyz(latitude, longitude, radius=1.0): # Convert latitude and longitude from degrees to radians lat_rad = math.radians(latitude) lon_rad = math.radians(longitude) # Calculate the Cartesian coordinates x = radius * math.cos(lat_rad) * math.cos(lon_rad) y = radius * math.cos(lat_rad) * math.sin(lon_rad) z = radius * math.sin(lat_rad) return x, y, z # Example usage: latitude = 37.7749 # San Francisco, CA longitude = -122.4194 radius = 6371.0 # Earth's radius in kilometers x, y, z = lat_lon_to_xyz(latitude, longitude, radius) print(f"X: {x}, Y: {y}, Z: {z}")

In this code:

  1. lat_lon_to_xyz is a function that takes latitude, longitude, and an optional radius (defaulting to 1.0, which corresponds to a unit sphere) as input.

  2. It first converts latitude and longitude from degrees to radians using math.radians.

  3. Then, it calculates the Cartesian coordinates (x, y, z) using the Haversine formula.

  4. The result is a point in 3D space, where (x, y, z) represents the position of the given latitude and longitude on the surface of a sphere with the specified radius.

Keep in mind that this conversion assumes a perfect sphere for the Earth. For more accurate modeling, especially when dealing with large-scale geospatial applications, you may want to use more complex ellipsoidal models or reference systems like WGS84.
