TOPIC 8

Develop an R-based software, which will perform the following tasks:

1. 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, perform the selections in the graphical user interface (GUI) of your R script,
2. determine the characteristics of each trajectory according to the parameters: diffusion distance, straightness, duration of travel, mean travel velocity and fractal dimension, 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.
4. 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.
