Introduction
This is the User Guide for the mobile application EDCA (the Emergency Data Collector for
Android™)*, developed for Google's well-known open source operating system for mobile devices:
Android (Android Developers 2013a).
The purpose of the application (the App) is to facilitate simultaneous data collection by many users
in an emergency setting. The main features included to achieve this is the utilization of the built-in
GPS sensors present in many modern mobile devices running the Android operating system (OS),
the use of the Google Maps Android API v2 (Application Programming Interface; Google
Developers 2013) for displaying maps and the possibility to store geographic objects with attributes
on the device in case internet connectivity is lost. Google Maps also provide the App's base maps.
