APPLICATION of GOOGLE API and KML to DRAW PATH from SOURCE to DESTINATION on ANDROID PHONE Dr International Journal of Advanced Engineering Technology E-ISSN 0976-3945 Research Paper APPLICATION OF GOOGLE API AND KML TO DRAW PATH FROM SOURCE TO DESTINATION ON ANDROID PHONE Dr. Khanna SamratVivekanand Omprakash, Mr Pritesh Patel Address for Correspondence Information Technology Dept, ISTAR, Sardar Patel University, VVNagar, India ABSTRACT Today google is constantly trying to implement innovative ideas in science and engineering. This paper presents the implementation of KML to find path from source to the destination on google android phone. Google provides many APIs to implement its services. Here we present methods to draw path from given source to the destination. Drawing path can be useful in many applications like travelling application, driving direction and projecting the path where our child moves using mobile implementation. KEY WORDS Google API, KML, Google Earth, Graphics, Keyhole, KMZ, Android INTRODUCTION Table 1 Now a day’s android phone market is popular among File Extension .kml, .kmz the people for many useful applications. This paper application/vnd.google-earth.kml+xml, MIME Type for kml application/vnd.google-earth.kmz represents the use of KML and google API to draw for kml path from specific source to the destination. Drawing Developed By Keyhole, Inc. 2001, Google path from one place to another is used to know the Uses in Graphical Information System way in which we can reach to the destination. By Parent Language XML knowing the co-ordinates i.e. longitude and latitude We can use KML to: of the specific location we can draw the path to that • Specify icons and labels to identify locations on location. This can be useful to the person to know the the planet surface path or can locate the position where he is located. • Create different camera positions to define With the help of these KML we can locate the place unique views for each of your features or path to the unknown location from our current • Use image overlays attached to the ground or location. screen OVERVIEW OF GOOGLE API • Define styles to specify feature appearance Google provide many services to the developers to • Write HTML descriptions of features, including design various useful applications. Among all hyperlinks and embedded images services Google API is an interface for accessing • Use folders for hierarchical grouping of features various services provided by google. Google offers • Dynamically fetch and update KML files from variety of API for developers. The API may be used remote or local network locations for Google Apps, Google Analytics, Blogger, Google • Fetch KML data based on changes in the 3D Base, Google Book Search, Google Calendar, Google viewer Code Search, Google Earth, Google Spreadsheets, • Display COLLADA textured 3D objects Google Notebook and Picasa Web Albums.

Path can also be drawn on map using kml. Many applications display KML, including Google Earth, Google Maps, Google Maps for mobile, NASA WorldWind, ESRI ArcGIS Explorer, Adobe PhotoShop, AutoCAD, and Yahoo! Pipes [3]. Figure 1 shows all the elements used in KML file along with abstract elements. Figure. 1 Android Architecture (developer.android.com, 2011) Android is a privilege-separated operating system, in which each application runs with a distinct system identity (Linux user ID and group ID) and parts of the system are also separated into distinct identities (developer.android.com, 2011). Implementation To implement the google API on android phone we have to add Google API library and set built target as Google API. We also need to set the permission in AndroidManifest.xml file like below: <manifest Figure 1 [7] xmlns:android="http://schemas.android.com/apk/res/ About Android android" Android is an operating system (OS) developed by package="com.example.package.name"> Open Handset Alliance (OHA).

The stated goal of the OHA is to “accelerate innovation in mobile and offer consumer </manifest> a richer, less expensive, and better mobile experience”. By providing an open development To add MapView control we need to code the platform, Android offers developers the ability to following in layout file like: build extremely rich and innovative applications. <?xml version="1.0" encoding="utf-8"?> Developers are free to take advantage of the device <com.google.android.maps.MapView hardware, access location information, run background services, set alarms, add notifications to xmlns:android="http://schemas.android.com/apk/res/ the status bar, etc.( developer.android.com, 2011). android" Basic architecture of android is shown in fig. 1. android:id="@+id/mapview" Android OS is built on the Linux 2.6 kernel.

Google Earth is a free, downloadable application that works as a browser for all sorts of information on Earth. It uses satellite imagery to grab, spin, pan, tilt and zoom down to any place on Earth. Students can explore every corner of the globe, measure distances, create their own virtual tours, and share their tours with others. You can also create and download layers of information and view them in geographic context. Why use it? Students can use Google Earth to: • study natural and political maps • learn map reading and navigation • visually explore historical, news, and census data • annotate locations and share with others • create their own 3D models to overlay on maps • download geographically-referenced information created by others Instructional Ideas Expert Tip Elementary.

    Google Earth 101 A lesson about the basics of the Google Earth program, and how to use it with the REAL storm surge visualization tool. How does Google Earth Display Maps? • Using sets of information called LAYERS http://www.townofbernalillo.org/img/gislayers.jpg Earth view with NO LAYERS selected. (This is a bare map) Earth view with ‘Borders and Labels’ LAYER selected. (This is a map with one layer) In Google Earth, LAYERS are sets of information that you can stack onto your map. Google Earth Basics This is a map of the northern Gulf of Mexico without any layers. Selecting LAYERS by clicking the boxes can let you see sets of information at the same time. They ‘stack’ on top of each other like a set of transparencies. Select the ‘Places’ ‘Roads’ and ‘Weather’ LAYERS and you can read a current weather map using major roads for reference. BUT BE CAREFUL!....... Too many layers = TOO MUCH INFORMATION If too many map layers are turned on, it can make the map unreadable! Be sure to turn on only the layers that you need! Google Earth Basics Turn layers off by clicking the checked boxes. To remove all layers, click the ‘Primary Database’ box. To turn off “Tour Guide” across the bottom of you map, click on the double down arrow just to the left of the title. All ‘Borders and Labels’ layers on All of the sub- layers in the SOME ‘Ocean’ ‘Ocean’ layer are layers on, but turned on and not all visible If a LAYER is marked with a [+] or a ∆, you can expand the selection to see a subset of layers by clicking on the symbol.
