4.2 Mobile based applications
One of the most important components in emergency
management is real-time data collection at the location and
monitoring of the events at regular intervals. Further generation
of spatial databases along with requisite attribute data on certain
features like medical facilities, relief shelters, field observation
stations etc. in this regard, Global Positioning System and other
localization technologies, wireless communication, and mobile
computing play a key role. Advances in the technologies for
data acquisition and data access are enabling more and more
applications of geospatial data and location-based services.
With the advancement of new and emerging technologies and
integrated lightweight device like palmtop or Personal Digital
Assistant (PDA) with full fledged GPS receiver, Photo-camera
and wireless communication, mobile device based solutions
have become very suitable to capture field information along
with photographs and geographic information (Latitude and
Longitude). A prototype mobile application was developed for
flood relief management. The architecture of the application
was shown in figure -6.
4.2.1 Application on flood relief management
When a flood disaster event occurs the first and fore most
activity that will be taken up with high priority is the relief and
rescue which includes evacuation of the people and movable
property, organizing relief camps, air dropping of food and
material, medical facilities etc. This phase is the most critical
and for managing the relief activity actions have to be taken on
the spot for which reliable information is required. Timeliness
in supply of information, organizing resources and manpower
are the essential components. The information required during
this phase is extensive and critical since the actions have to race
against time. The primary information will be on impact of the
event, the extent of the area affected, location specific details,
population affected, availability of resources for evacuation of
the people and means of evacuation, quick assessment of
damages. The process of collection of information by
conventional means is time consuming and not cost effective.
Some of the data has to be updated at frequent interval
depending up on the progression / recession of the flood wave.
The basic data required from the field for relief management
has been identified and the application is being customized. It
can be deployed to the filed for collection of the information
and sending to the central server through wireless connectivity.
The application has a provision for capturing field photographs
with location coordinates which enables the data for plotting on
to map server. The filed data will be ingested into the database
which can be used as a valuable input for geospatial models for
analysis and decision making. Some of the parameters collected
through the application are shown in figure 7(a & b).
