Purpose
Platform
The software has been tested on Android 2 (Froyo/GingerBread ) and Android 4(IceCreamSandwich)
The software can be installed on jellyBeans
The application has been developed on the Open Source Android mobile platform, allowing it to run on a wide range of devices including modern, high performance smartphones
Major Module of the application are:

6
Customizing the Software using 1)Load project manager2)Config manager3)Preference manager
7
Select the state and download the project list from the server.
Saves all the detail information about the User and the project in which he is working in the field.
8
Setting the camera parameters in Preference manager
Getting location via GPS by triangulation. Parameters are Latitude , Longitude and Altitude with best possible accuracy.
Satellite parameters acquired via GPS
9
Acquiring the field Information
10
The photo is acquired along with the direction of the photo
11
Choosing Assets – asset category, Asset TypeChoosing Descriptions
12
photo is then watermarked and photo data encrypted and ready to be sent to server
Textual data is encrypted and stored in mobile device
Header and footer watermarked providing details of Project Assets/Activities Information
13
14
The Field data is ready to be sent to server and/or email
The software will check the connectivity and prompt user to send immediately or send later via Send manager
15
The field data - photo and related textual information is stored in server.
The textual information is decrypted, parsed and stored in relational database
The server software fetches this data and analyze it according to the project name and generates kml file
The kml file is ready to be downloaded by the user while visualizing in mobile device
Relational database stores field data
Kml file downloaded via Project View Manager
The data is decrypted at server
View Project menu contains following sub-menu
16
User can view sent data spatially through IWMP site ,in Bhuvan,Google Earth or on mobile.
Downloading kml file

Integration Of GeoStamped Location with :-Integration Of GeoStamped Location with :-Mobile GOOGLE EARTHMobile GOOGLE EARTH
InstallationThe minimum requirement for running the application are:-
Android version 2.2 OS and above
GPS (Global Positioning System)
Orientation sensor
Camera 2Mp
SD Card
Minimum screen resolution of 480X320
Network Connectivity (2G/3G)
18
The software accomplishes field data collection in tamper-proof manner
The data transaction between software on the mobile device and remote server is online while acquiring field data and sending to server, thereby eliminating the need of any paper work
19
Future Scope :
Conclusion:
Sending of Multiple photos of the same position on the field at the same time
This Mobile applications allows for speedy, accurate and transparent decision making for district/block level planning It is near-real time experience of data collection
multi-temporal data collection of the almost same position on the field
Deploying strong security measures while encrypting/decrypting
Facilitating the sending of data via SMS with encryption/decryption using public/private key cryptosystem
