Resumo: Técnicas que buscam atender às necessidades do usuário no desenvolvimento de um produto, como a Engenharia de Requisitos (RE) e o User Centred Design (UCD), vem sendo cada vez mais utilizadas em diferentes áreas. A RE é uma área de informática que busca o desenvolvimento de métodos e técnicas para elaboração de software, enquanto o UCD é um processo de design iterativo, onde os designers focam nos usuários e os colocam no centro do processo de desenvolvimento. Este estudo abordou a aplicação dessas técnicas no desenvolvimento de um WebGIS direcionado para aplicações universitárias. Nesta pesquisa foi proposta uma interface para este WebGIS, com uma aplicação para auxiliar a navegação em ambientes internos e externos. O estudo de caso foi aplicado no campus do Centro Politécnico da Universidade Federal do Paraná (UFPR). A interface foi avaliada por meio de testes com usuários, utilizando tarefas que permitiam explorar a funcionalidade da ferramenta. A metodologia utilizada para medir a usabilidade foi elaborada por Brooke (1996) por meio da Escala de Usabilidade do Sistema (SUS), sendo a classificação desta escala adotada por Bangor, Kortum e Miller (2009) e Sauro (2011). Os resultados mostraram índices de pontuação baseados no SUS, que indicaram que o uso de técnicas de UCD permite melhorar o desenvolvimento de interface em um WebGIS.

Abstract: The techniques that seek to attend the user’s needs in a product’s development, like the Requirements Engineering (RE) and the User-Centred Design (UCD) have been increasingly used in different areas. The RE is a computer science area that seeks the development of methods and techniques to software elaboration, while the UCD is an iterative design process, where designers focus on users and place them at the center of the development process. This study approached the application of these techniques to developing a WebGIS oriented to university applications. In this research an interface to the WebGIS was proposed, with an application to assist the navigation in indoor and outdoor environments. The study case was applied in Polytechnic Center campus of Federal University of Paraná (UFPR). The interface was evaluated through tests with users, using tasks that allowed to explore its functionality. The methodology used was elaborated by Brooke (1996) to measure the usability through the System Usability Scale (SUS), and the classification of this scale adopted by Bangor, Kortum and Miller (2009) and Sauro (2011). The results show punctuation indices based on the SUS, what indicated that the use of UCD techniques allow to improve the interface development in a WebGIS.

Abstract This work presents a geological-geotechnical risk map of gravitational mass movements and a susceptibility map to shallow translational slides to Vila Nova community, located in the municipality of Colombo, Brazil. The first map was created through a qualitative mapping methodology and the second one was elaborated using a deterministic method of slope stability. An aerial photogrammetric survey with UAV technology was performed, as well as field reconnaissance, laboratory testing, and geoprocessing techniques. Seven slope failures were identified as well as a range of other evidences of instability associated with the predisposition of the terrain to erosive and gravitational movements linked to human intervention without urban planning and engineering techniques. Moreover, the qualitative and quantitative analyses pointed out that 13% to 9% of the study area, respectively, are in a very high-risk condition for landslides. Thus, the resulting cartographic products are presented as an important technical contribution for landslide risk management as well as land use planning for reducing the geotechnical problems faced on site.
