Abstract

U radu je opisan i razvijen geoprostorni sustav objavi-pretplati za uređaje s operacijskim sustavom Android. Poslužitelj u tom sustavu koristi bazu podataka PostgreSQL s dodatkom PostGIS za pohranu i obradu prostornih objekata. Poslužitelj je razvijen kao usluga REST koja omogućuje korisnicima dodavanje novih pretplata, otkazivanje postojećih te slanje objava. Klijentska aplikacija se koristi za primanje i stvaranje objava koje se u sustavu razmjenjuju korištenjem usluge GCM. Klijent i poslužitelj razmjenjuju poruke u formatu JSON u kojima definiraju tri tipa geoprostornih objekata: točka, linija i poligon. Analiza sustava je provedena korištenjem Apache benchmark alata i posebno napisanom aplikacijom koja simulira stvaranje velikog broja pretplata.

Abstract (english)

This paper describes geospatial publish-subscribe system for devices with Android operating system. In this system server use PostgreSQL database with PostGIS extension for storing and processing geospatial objects. Server is developed as REST service which allows users to define their subscription and to send messages. For the exchange of messages is used GCM service. Client and server are exchanging JSON messages that define three types of Geospatial objects: point, line and polygon. System analysis was performed using Apache benchmark tool and with additional application that simulates the creation of a large number of subscriptions.
