Is the following the correct way to calculate the straight line distance between two points / locations by longitude and latitude?

```
julia> using Geodesy
INFO: Precompiling module Geodesy.
julia> x_lla = LLA(-27.468937, 153.023628, 0.0)
LLA(lat=-27.468937°, lon=153.023628°, alt=0.0)
julia> y_lla = LLA(-27.465933, 153.025900, 0.0)
LLA(lat=-27.465933°, lon=153.0259°, alt=0.0)
julia> distance(x_lla, y_lla)
401.5431022017651
```

Is there a simple / easy way to transfer the longitude and latitude into the x value and y value (cartesian coordinate system) of a point in a planar map?
