- Data Collection Methodology to Assess Road Pavement Condition Using GNSS, Video Image and GISPublication . Santos, Bertha; Almeida, Pedro Gabriel De; Maganinho, Leonor Graciete de OliveiraTraffic loads, along with the environment, damage pavement over time. The degradation of pavement quality is reflected in the development of a diversity of pavement distresses, such as cracking, deformation or deterioration. These distresses may occur on the surface and/or in the pavement structure, having a determinant role in pavement’s quality. Aiming to increase the degree of reliability of the pavement distress data and reduce pavement observation time and visual inspection operations cost, this work presents the main steps proposed for a methodology to observe, record and evaluate flexible road pavement distresses to assess the quality of road pavements. This methodology is based on an in-vehicle inspection using GNSS and video image capture devices and in the use of Geographic Information System (GIS). Validation of the proposed methodology was made through a case study by comparing the results obtained on the in-vehicle inspection to those from a traditional visual inspection performed on foot. The similarity of results obtained by the two approaches allowed to conclude about the feasibility of the proposed methodology. Among the main advantages of the proposed methodology a highlight is on the possibility to identify, quantify and locate the most severe pavement distresses through the use of spatial tools available on GIS, producing information maps and reports that can be used in the decision-making process about road pavements rehabilitation and conservation.
- When past and future meet in architecture teaching: heritage and GISPublication . Santos, Bertha; Martins, Ana Maria Tavares; Campos, Inês; Gonçalves, Jorge H.G.; Almeida, Pedro Gabriel deThis article aims to present some of the teaching methodologies applied in the Integrated Master degree in Architecture at the University of Beira Interior, Covilhã (Portugal). The discussion focuses on the collaborative and interdisciplinary approach adopted for the teaching/learning process, particularly the courses of History of Portuguese Architecture, Project III and Geographical Information Systems (GIS), all belonging to the 3rd year. The aim of this approach is to encourage project-based learning through the use of spatial tools and new technologies to analyse and manage architectural spatially referenced data. As students present a heterogeneous level of general History knowledge and of History of Portuguese Architecture in particular, it was necessary to introduce the acquisition of knowledge to achieve the required competence on scientific work, research, adequate scientific terminology and architectural dating to finally achieve the expected results. Interdisciplinary state of the art and knowledge gathering performed by the students concerned Architecture, GIS, Civil Engineering, Heritage, and History. Consequently, an interdisciplinary connection was achieved during student research of religious Portuguese heritage in Covilhã by implementing a GIS based inventory and analysis. Concerning the curricular unit of Project III, design studies aiming to evaluate the potentialities of a site are developed based on requests from external institutions. These requests are incorporated in the course program on an annual basis, adapted accordingly to the defined skills to be achieved. For students this is an important experience as they must respond to a real design problem. The conjugation with the GIS curriculum complements all the necessary study for a better understanding of the site and its surroundings, thus developing a useful spatial database for future reference. This collaboration with the GIS curricular unit began in 2016/2017 with Project III and evolved in 2017/2018 to History of Portuguese Architecture through practical works gathering knowledge from multiple subjects. Regarding the experience of teachers and students, the use of GIS in Architecture has proven to be a success, given students’ skills on the use of new technologies. This also allows them to contact with other scientific, technical and technological realities, preparing students for a demanding international work context.
