DEFINITIONS

Situational Awareness

Situation awareness (SAW) is the perception of environmental

elements within a volume of time and space, the comprehension of

their meaning, and the projection of their status in the near future.

Introduction

In the SAW acquisition process, the majority of failures happen

on perception stage.

SAW oriented systems on decision-making support depends on

quality data and information to provide humans the better

comprehension that whats are happening on the environment.

GoalArchitectureConclusion

Introduction

To support SAW, the information visualization is used as a

manner to present products and by-products of processing

steps of the emergency intelligence, called situation

assessment. In each set of information produced, the expert

observes and takes guidance in the light of visualizations, and

then makes the decision and acts according to the level of

SAW.

Problem

The research problem is the lack of a data visualization framework

model to help in the uncertainty data analysis for improving SAW in

emergency management systems.

Goal

The present study aims to describe the creation of a framework

that integrates and disseminates issues related to quality of

information and quality of representation, involving the application

of graphical representation techniques of uncertainties generated by

the dimensions of completeness, consistency and dimensions related

to time, such as timelines.

GoalArchitectureConclusion

The Process

The majority of existing solutions found, aims salve SAW

problems in the decision-making process, helping the operator

to achieve the SAW about some scenario.

The visualizations found use some representations techniques,

to help the operator to understand the situations like the use

of colors. To show some speci�c information, in our case, we

merge all the better techniques founded, and created the �nal

visualization.

The Framework

It was structured a framework that speci�es the steps for the

construction of visualizations aware of uncertainty which meet

situation awareness requirements in management systems of

emergency situations.

The solution aims to solve quality problems in emergency call

decision-making, besides contributing to the acquisition,

maintenance and recovering SAW state.

GoalArchitectureConclusion

The Process

At �rst, it is necessary to relate speci�c sub-processes of

information visualization with the acquisition phase.This

approach is relevant for two reasons:

visually encode the raw data obtained from heterogeneous datasources, orgraphically represent objects and attributes identi�ed.

GoalArchitectureConclusion

The Process

This abstraction is achieved by using graphics variables such as

color, shape, size, animation, among others.

When combined, these techniques allow the experts to easily

be aware of the situation due to the possibility to draw

attention to the information that they consider important.

Results

With result of acquisition and fusion steps, it was possible to

develop the framework in order to de�ne uncertain information

considering the phases of situation assessment.

With this framework, it is expected that views dedicated to

emergency rule can be created in synergy with the other steps

of situation assessment.
