Project Members: Arun Bhandari Nishanta Khanal DEVELOPMENT OF ANDROID AND WEB APPLICATION FOR DISASTER RISK MANAGEMENT THROUGH CROWDSOURCING SUPERVISORS: MR. SHASHISH MAHARJAN MR. UMA SHANKAR PANDAY Project Members: Arun Bhandari Nishanta Khanal JULY 28 , 2014

introduction Disasters: Location Based Services (LBS): Natural or human induced Mostly inevitable Risk reduction, safety and better rescue is what is necessary Location Based Services (LBS): Services that extract the location information of the people from GPS enabled devices Popular, effective and easy to use Provide the information on where a person is

background Kathmandu valley faces the risk towards severe earthquake damage Other disasters/ accidents also occur every once in a while Rapid urban growth with unplanned settlements Lack of efficient and sufficient emergency service providers But, The challenge of finding where a victim is trapped or where the rescue service is needed still prevails

objectives To develop a system for communication between victims and rescue service operators/ non-victims in a post disaster scenario Sub-objectives To design and develop a database To enable a system of communication with server containing database To build a system enabling users to report, view map and call for emergency help To design user interfaces (android and web) To design and implement a proper administrative component

Methodology PLANNING RESEARCH SYSTEM DEVELOPMENT Testing and debugging Database creation Server backend development Web application development Android Application development Testing and debugging

Database creation PostgreSQL was used as DBMS METHODOLOGY -> SYSTEM DEVELOPMENT PostgreSQL was used as DBMS PGADMIN III was used as frontend Tables were created using PGADMIN III UI and writing SQL

Server backend development METHODOLOGY -> SYSTEM DEVELOPMENT Server backend development was done by writing PHP scripts Apache server was used to run the scripts The scripts are designed to be supplied with data using post method Scripts were written such that they returned data in JSON or GEOJSON format

Server backend development ( Contd…) METHODOLOGY -> SYSTEM DEVELOPMENT Following tools were used XAMPP to run/emulate and configure APACHE server on our pc Notepad++ to write PHP scripts Google chrome to test and debug scripts Mozilla Firefox to test and debug scripts

Web application development METHODOLOGY -> SYSTEM DEVELOPMENT Web application was developed using multiple languages PHP JS Html5 CSS 3 Multiple files were created for different components to make it easy to add and edit components of the web site CSS and JS were saved in separate files as well External libraries were downloaded and used as well as referenced as required Graphics and icons that were to be used were created Testing and debugging

Web application development (Contd…) METHODOLOGY -> SYSTEM DEVELOPMENT Following external libraries were used Bootstrap 3 jQuery AJAX Leaflet Charts.js Mapbox API Google geocoding

Web application development ( Contd…) METHODOLOGY -> SYSTEM DEVELOPMENT Following software and tools were used XAMPP to run/emulate and configure APACHE server on our pc Notepad++ to write scripts Google chrome to test and debug web application Mozilla Firefox to test and debug web application Photoshop CS6 to create graphics and icons

Android application development METHODOLOGY -> SYSTEM DEVELOPMENT Android application was developed using multiple languages Java XML External libraries were downloaded and added to the build path Multiple activities were created for the android application Graphics and icons that were to be used were designed Offline data to be used was acquired Testing and debugging was done

Android application development(Contd…) METHODOLOGY -> SYSTEM DEVELOPMENT Following external libraries were used Mapsforge Graphhopper Following software were used Eclipse Java SDK Android SDK

Results Database Server backend Web application Android Application

RESULTS DATABASE FIVE TABLES: user_auth: to store user information (username, contact, email address, type) reports: to store information each report contains (type, level, description, location, date, etc. ) likes: to store the report id, username and vote (yes or no) report_types: to store the type of report emergency: to store information about emergency request (username, location, date, time) Fig: Flow Database Schema Design

SERVER BACKEND Scripts written in PHP RESULTS Scripts written in PHP Help in extracting required data from the database according to the client request Fig: Flow Diagram of Server Processing

WEB APPLICATION Clean and easy to use User Interface Functionalities: RESULTS WEB APPLICATION Clean and easy to use User Interface Functionalities: Map-view News Feed Submit new report Search for nearest Hospital Find shortest route Admin components with privileges like manage users and reports, view statistics, etc. Fig: Website Homepage UI

ANDROID APPLICATION RESULTS Application along with a widget for emergency service request Six activities/ screens: Login Page Registration Page News Feed Map Screen Disaster Report Page Disaster Details Screen Facility of routing and finding nearest hospital Emergency service request possible through widget Fig: Android Application Splash Screen Fig: Android Application Map-view

discussion Choice of OpenStreetMaps as the base map justifies data acquisition through crowd sourcing One click for emergency reporting is helpful to victims Users are responsible of validating the reports

Limitations Android application is platform dependent Error in GPS coordinates We do not guarantee rescue services, a third party involvement is required

conclusion The initial objectives have been achieved The application can be of use to overall disaster resilience in Nepal Addition of features such as alerting respondents in the vicinity

Recommendations Proper marketing is required as crowd sourcing means nothing if crowd don’t use it Working on how to mitigate the damages caused due to hazards Involving responsible parties to manage the system and relay information to mass Addition of features such as alerting respondents in the vicinity, broadcasting safety tips

Server backend development (Contd…) METHODOLOGY -> SYSTEM DEVELOPMENT An example GEOJSON String { "type": "featurecollection", "features": [{ "type": "feature", "geometry": {"type": "point", "coordinates": [0.0, 0.0]}, "properties": {"name": "point1"} }, { "type": "feature", "geometry": {"type": "point", "coordinates": [10.0, 10.0]}, "properties": {"name": "point2”}] }
