2. 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

3. 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

4. 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

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

6. 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

7. 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

8. 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

9. 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

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

11. 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

12. 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

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

14. Results
Database
Server backend
Web application
Android Application

15. RESULTS
DATABASE
FIVE TABLES:
user_auth: to store user information (username, contact, 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)

16. SERVER BACKEND Scripts written in PHP
RESULTS
Scripts written in PHP
Help in extracting required data from the database according to the client request

17. 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.

18. 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

19. 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

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

21. 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

22. 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

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”}] }
