Location-Based Applications for Smartphones

Abstract

This paper presents an implementation of a location-based service developed for smartphone devices. It also covers a review of the need for location-based services and methods of location acquisition, which include GPS, cell-stations, wireless access point and IP address based Geo-location lookup positioning. The paper covers a review of contemporary technologies for development of software systems based on the location-based services and their use on smartphone devices. The paper presents the implementation of a GIS designed to provide venue information based on the location information of smartphones with Android operating system. Apstrakt: U radu je predstavljena primena usluge bazirane na lokaciji, kreirane za pametne telefone. U njemu se analizira potreba za uslugama baziranim na lokaciji, kao i metode utvrđivanja lokacije, među kojima su GPS, lociranje pomoću baznih stanica, bežičnih mreža i utvrđivanje lokacije pomoću IP adrese. Rad sadrži i pregled savremenih tehnologija za izradu softverskih sistema baziranih na lokaciji i njihovu upotrebu na pametnim telefonima. Predstavljena je implementacija jednog geografskog informacionog sistema dizajniranog da pruži informacije o ugostiteljskim objektima, koje su u blizini pametnih uređaja sa Android operativnim sistemom, bazirane na njihovoj lokaciji.

Smart tourism and location-based services architectural model

“…The Tracking services can be implemented by the Location-Determination-Service (LDS), which in turn depends on the support of the smartphone GPS receiver; there are other methods for LDS, which can be used in combining the Cell Phone Towers, Wi-Fi Access Points, the IP address geo-location and the user-defined location. The LDS service is performed by recording a set of coordinates including latitude, longitude, and then calculated to find the altitude (Lazović et al, 2015).…”

“…All are connected through computer networks. The GIS software provides functions and utilities to manipulate geographical information, and it has specialized tools for querying, analyzing, image viewing, data mapping, and reports generating (Lazović et al, 2015).…”
