GeoStamping - A field Information collection mobile application 1 By: Subrata N. Das, Saurabh Gangwar, Ashok K. Joshi RRSC –Central, Nagpur Conference on Geospatial Information technology and Applications 24 January, 2013 THEME: Mobile Mapping

2 Version 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: GeoStamp Manager About Exit The icon which appears on mobile for GeoStamping is: 3

4 Start Manager Getting latitude, longitude,Accuracy, Altitude Geostamp Configure the project Load project Customizing the software Stop Acquiring the field data Start Stop Turn on GPS Flowchart Acquiring photo and direction of photo Asset description Encrypting and watermarking Sending Field Data Is Internet connectivity available Data send later Data sent to server N Y Preference manager

Manager menu contains following sub-menu 6 Customizing the Software using 1)Load project manager 2)Config manager 3)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 Type Choosing 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 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

17 Integration Of GeoStamped Location with :- Mobile GOOGLE EARTH

Installation The 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
