Android Application Development for GPS-Based Tree Location Tracker

摘要

Android application is becoming very popular nowadays due to the expansion of smartphone devices. With the incorporation of GPS devices in smartphones, Location Based Services (LBS) have become a trend in the past few years. Using this software application, the user's current location will be retrieved and then use the acquired data to provide information for that location. In line with the National Greening Program, the City Government of Butuan spearheaded the "Balangayan Grow a Million Tree Project". Funds were allocated for the various activities associated with this project such as site preparation, seedling production, hauling of seedlings to planting sites including the maintenance and protection of the established plantations. The CGB needs to keep a track of the numbers of the seedlings planted so that the funds allocated are justified. There is need of a tool that will aid the CGB to monitor the site and the seedlings planted in it. With the use of Android Technology and GPS enabled handset, seedlings may be located anywhere in the field. Once the location is acquired, the information obtained can then be attached to various media in the form of meta-data. Geotagging is the process of adding geographical information to photographs. Information such as species name, cost, date planted and planters are stored in the SQLite. SQLite database is an integral part of the application program, due to the server-less design of SQLite applications, and this database require less configuration than client server databases. Aside from Geotagging, Android Technology is also capable of defining a virtual boundary around a real world geographical area. Geofencing allows automatic alerts to be generated based on the defined coordinates gathered during surveys. If the surveyor have really entered the area then the administrator will be notified otherwise the area to be surveyed will be marked as undone.
