Interpolate between 2 GPS locations based on walking speed

Question

Problem:

---

Given two locations:

L₁ = (latitude₁, longitude₁, timestamp₁), L₂

Answer 1

Yep. Linear interpolation.

L1 = (1, 2, 3)
L2 = (4, 5, 6)
desired_number_of_interpolation_points = 9
interpolation_points = []

lat_step = (L2[0] - L1[0]) / (desired_number_of_interpolation_points + 1)
lon_step = (L2[1] - L1[1]) / (desired_number_of_interpolation_points + 1)
time_step = (L2[2] - L1[2]) / (desired_number_of_interpolation_points + 1) 

for i in range(1, desired_number_of_interpolation_points + 1)
    interpolation_points.append((lat_step * i, lon_step * i, time_step * i))
