Lecture 6 geolocation
- 1. App Design for Business Topic: Geolocation Topic Number: 6
- 2. Key topics / learning outcomes of this lecture • Learn about Geolocation and how useful it is for application design. 2
- 3. What is Geolocation? • Geolocation is the identification of the real-world geographic location of an object. It provides: • Location awareness • Location tracking • Geofencing – a predefined set of boundaries; • Activity recognition – walking, running; Geolocation originates from the words “geographic location”.
- 4. Geolocation Uses • Applications – banking, ecommerce, media, telecommunications,online gaming; • Criminal investigations – money laundering, trafficking, terrorism detection; • Fraud detection – Bank payment location mismatch; • Geo marketing – advertisements relevant to that location; • Regional licensing – online casinos must know where there customers are by law; – online broadcasters can stream content in certain locations so as to comply with geographic licensing regulations; • Content Targetting – local weather; – advertising; B4004A L1 4
- 5. Systems for Finding Device Location • Global Position System (GPS) – hardware: satellite; • accurate to 5 – 100 meters approx; • Nearest cell tower – hardware: cell tower; • urban areas – accurate to 500 – 1000 meters approx; • suburban areas – accurate to 1000 – 2000 meters approx; • Nearest Wi-Fi hot spot – hardware: Wi-Fi hot spot equipment; • accurate to 20 – 50 meters approx; B4004A L1 5
- 6. Internet Geolocation Use • Internet Protocol (IP) address; – data provided includes country, region, city, postcode, latitude, longitude and timezone; • Geolocation uses a WHOIS lookup service and retrieves registrant’s physical address for this data; • MAC address; – geolocation can be associated with a MAC address; • RFID; – geolocation can be associated with RFID; • Wi-Fi positioning; – geolocation can be associated with Wi-Fi equipment; • Device GPS co-ordinates; – geolocation can be associated with GPS systems; B4004A L1 6
- 7. Google Servers • The data collected is sent to Google servers • Google return the location information B4004A L1 7
- 8. Latitude and Longitude B4004A L1 8
- 9. Geolocation for Android Tools Required Install the latest version of Google Play and • an AVD that runs Android 4.2.2 or higher or • a compatible Android device B4004A L1 9
- 10. Reference data source • NETWORK_PROVIDER; – access Wi-Fi and cell towers; • GPS_PROVIDER; – access GPS; • PASSIVE_PROVIDER; – access any current provider; (not recommended except for quick reference when an app is first started). B4004A L1 10
- 11. Obtain Device Location • Set permissions in the Android manifest file – ACCESS_COARSE_LOCATION; • access the network provider; – ACCESS_FINE_LOCATION; • access GPS or the network provider; – INTERNET; • add this if you want the network provider to include the Wi-Fi information; B4004A L1 11
- 12. Seminar • In the Seminar to this tutorial, we will be working through a video tutorial to set up a functioning location app that will provide the latitude and longitude co-ordinates of the device. B4004A L1 12
