Abstract

U ovom radu predstavljena je mobilna aplikacija za mapiranje skijaških staza i žičara na temelju prikupljenih podataka korisničkih lokacija. Mobilna aplikacija napravljena
je za korisnike Android pametnih telefona. Baza podataka korištena za pohranu
svih korisničkih podataka je Firebase Cloud Firestore baza podataka. Nad skupom
prikupljenih korisničkih podataka provedeno je grupiranje podataka aglomerativnim
algoritmom kako bi se odredili položaji skijaških staza i žičara. Aglomerativni algoritam
je odabran jer se nakon analize rezultata algoritama pokazao kao najispravniji.
Osim prikaza skijaških staza i žičara aplikacija nudi i ostale funkcionalnosti kao što je
praćenje kretanja aktivnih prijatelja, prikaz kretanja ostalih trenutno aktivnih korisnika
te prikaz svih GPS lokacija na temelju kojih su skijaške staze iscrtane.

Abstract (english)

This work presents a mobile application for mapping ski slopes and ski lifts based
on the collected user location data. The mobile application is made for Android
smartphone users. The database used to store all user data is Firebase Cloud Firestore
database. Clustering is performed on the collected user data using the agglomerative
algorithm to determine the positions of the ski slopes and ski lifts. The agglomerative
algorithm was chosen because it proved to be the most accurate algorithm after
analyzing all of the algorithm results. In addition to displaying ski slopes and ski lifts,
the application also offers other functionalities such as tracking currently active friends,
tracking other currently active users and a displaying all GPS locations based on
which the ski slopes are plotted.
