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.

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.
