TOPIC 8
Develop an R-based software, which will perform the following tasks:
-
download from the OpenSky Network online database the observations of the trajectory of a randomly selected aircraft on a randomly selected flight over at least five days, in uninterrupted continuity (1)
-
perform the selections in the graphical user interface (GUI) of your R script,
-
determine the characteristics of each trajectory according to the parameters: diffusion distance, straightness, duration of travel, mean travel velocity and fractal dimension (2),
-
using the R library trajr, (4) perform basic statistical analysis of the parameters of daily trajectories from (3): arithmetic mean, variance, quartiles, boxplot, estimate of the density function of the experimental statistical distribution, analyze and interpret them.
-
Demonstrate the application of the developed software support on a selected example of use.
-
In the final project report, describe the problem, describe the method and the developed software support in the R environment, present and interpret the results, and form a conclusion.

Use renv to install the correct dependencies using
renv::restore()
OpenSky access also requires credentials placed in a .env file, for which an example is provided in .env.example.
