About Project

Modeling, querying and interactive visualization of spatiotemporal data

The general scope of the MOST Project (INESCTEC and University of Aveiro): Recent technological advances have allowed the collection of data volumes on the evolution of spatio-temporal phenomena much higher than the existing capacity to analyze them and extract relevant information in various scientific areas. Therefore, tools capable of automating processes of quantitative analysis of spatio-temporal data are increasingly necessary, ensuring levels of objectivity, precision, and reproducibility compatible with the performance of scientific work. Currently, there are well-known tools for processing static spatial data (e.g., Geographic Information Systems), but support for modeling dynamic phenomena is limited, often requiring a great effort in programming complex algorithms that are specific to a particular problem. This project focuses on the development of advanced tools for modeling and analyzing spatio-temporal data, using continuous representation models in space and time. The key element will be a data management system capable of modeling generic spatial transformations (e.g., shape change, size change, translation, rotation, aggregation or fractionation of entities or objects) representing the phenomena of interest over time. This system will be accessible through a query language providing functions for the management, query, and processing of large volumes of data. Methods will also be developed to create spatio-temporal representations from sequences of images or videos, and data visualization tools and user interaction. An integrated set of tools will be provided to simplify the conduct of studies on spatio-temporal phenomena. The goal is to reduce the time and effort that today is necessary to dedicate to the development of complex data management and processing procedures, thus freeing resources for the performance of the studies themselves. The proof of concept is based on two case studies involving the modeling of spatio-temporal phenomena with distinct characteristics. The first consists of modeling the propagation of forest fires from aerial images, with a view to conducting studies on carbon emissions to the atmosphere. The second consists of creating a database characterizing the morphological changes that cells undergo when they move in their own environment. The quantification of these characteristics is important in biological processes such as embryonic development or tumor formation. The origins of the data are microscopic videos. In the future, it is also intended that the results of this project can be applied in other areas, for example, in studies on coastal erosion, river silting, or others.

Alexandre Carvalho

Alexandre Valle de Carvalho has been a University Professor since 2001, and Assistant Professor in the Department of Computer Engineering (DEI) at the Faculty of Engineering of the University of Porto (FEUP) since 2009. He is a researcher at the Center for Information Systems and Computer Graphics (CSIG) at INESCTEC, since 2001 and senior researcher since 2009. The scientific area of Computer Graphics has been present throughout its academic path, starting with Raytracing and Radiosity Hybrid for the Calculation of Photorealistic Images, of 1994, in the Graphical Interface of the Input Module of Data from the VALORAGUA Model, from 1997, in the Image Synthesis for Virtual Environments Experiences with the RENDERCACHE technique, from 2001., culminating with his PhD entitled “Spatio-temporal Information Management and Visualization” in 2009. Furthermore, other professional activity in Geographic Information Systems, as a scholarship, technical staff and then as a researcher at INESC Porto, motivated the scientific study in this area and in the application domain of urban information management, eDemocracy and eGovernment. The joining of both areas - computer graphics and information systems - as well as the background in urban data management resulted in the theme and PhD work, in management and visualization of space-time information, completed in 2009, where he defended two hypothesis: one in information systems and another in information visualization. Alexandre performs research in these two areas until the present time. Furthermore, he has participated in a considerable number of research and development projects, framed by European projects, R&D national projects and specialized consultancy, having publications indexed in scientific conferences and journals. Regarding economic and direct knowledge extension to society, Alexandre founded SIAGHOS in 2012, towards systems and technology to support observational clinical studies. In this context, it conceived, produced and innovated in information systems to support the registration and analysis processes of observational clinical studies for hematology-oncology diseases. These systems were used by a considerable number of Portuguese hematologists, between 2012 and 2018. Furthermore, in 2015 Alexandre co-founded MITMYNID, an INESC TEC spinoff towards innovative solutions for the Transport and Logistics Sector. At MITMYNID, Alexandre participated in the coordination BIZCARGO and of projects with a high degree of innovation and in the elaboration and execution of proposals and provision of services where innovation is also evident. Examples of this are two P2020 demonstration projects and collaboration on two European projects. In the context of university management, Alexandre performed scientific and pedagogical coordination of curricular units, course groups and degree and master courses.
