How don’t tuten coordinates von Google maps in Cartesian coordinates; 

To convert latitude and longitude coordinates from Google Maps (which are in a geographic coordinate system) to Cartesian coordinates, you generally follow these steps:

1. **Understand the Coordinates**: Latitude and longitude are angular measurements, where latitude measures north-south position and longitude measures east-west position on the Earth's surface.

2. **Select a Cartesian Coordinate System**: There are multiple ways to define a Cartesian coordinate system, but commonly used systems include:
   - **ECEF (Earth-Centered, Earth-Fixed)**: A global 3D coordinate system centered at the Earth’s center.
   - **Local Tangent Plane (LTP)** or **ENU (East-North-Up)**: This is a local Cartesian system where a specific point on Earth (e.g., a location of interest) acts as the origin.  

3. **Convert Latitude and Longitude to Cartesian Coordinates in the ECEF System**:
   For the Earth-Centered, Earth-Fixed system, you can use the following formulas:
   \[
   X = (N + h) \cdot \cos(\text{lat}) \cdot \cos(\text{lon})
   \]
   \[
   Y = (N + h) \cdot \cos(\text{lat}) \cdot \sin(\text{lon})
   \]
   \[
   Z = \left( \frac{b^2}{a^2} \cdot N + h \right) \cdot \sin(\text{lat})
   \]
   Where:
   - \( \text{lat} \) and \( \text{lon} \) are the latitude and longitude in radians,
   - \( h \) is the elevation above the Earth's surface,
   - \( a \) is the Earth's equatorial radius (6,378,137 meters),
   - \( b \) is the polar radius (6,356,752 meters),
   - \( N = \frac{a^2}{\sqrt{a^2 \cdot \cos^2(\text{lat}) + b^2 \cdot \sin^2(\text{lat})}} \).

4. **Convert to Local Tangent Plane (if Needed)**: If you need a local Cartesian system, you can convert the ECEF coordinates to the Local Tangent Plane or ENU system.
