Resumo
Web mapping systems, or Web GIS, are important tools for geographic orientation and
spatial data analysis. In recent years, the use of these systems has increased, as well as the
challenge to ensure performance while the number of users and the data volume continue
to grow. The performance evaluation is an important activity to investigate and mitigate
systems performance issues. The workload is the starting point of the performance
evaluation and is responsible for sending resquests to the system under evaluation. The
reliability of the evaluation results is related to an appropriate load. Despite the importance
of web map systems, the literature as presented little efforts to model the workload of these
systems. In this dissertation, we present a methodology to collect and analyze data in order
to create a model of Web GIS users’ behavior and to instantiate the model in a workload
generator. We also propose a generic model, named MUSe-GM (Maps User Session
Generative Model), and present a characterization of the users’ behavior using data of
the access to a popular mapping application, collected by an extension developed for the
Google Chrome browser. The characterization results were used to develop an instance of
the behavior model and to implement a workload generator. The instance was evaluated by
testing in a realWeb map system, using the workload generator, and through simulations.
The results were compared with two other models from literature. The proposed model
in this dissertation was significantly different in several aspects compared to the other,
presenting a behavior closer to the real users’ behavior.
