DBCELLS - An open and Global Multi-Scale Linked Cells

Published in Brazilian Journal of Cartography, 2017

Land change models require large amounts of data, and are diffi cult to be reproduced, as well as to be reused. Some initiatives to open and link data increase the reproducibility of scientifi c experiments and data reuse. One pillar of the linked data concept is the use of Uniform Resource Identifi er (URI). In this paper, we propose DBCells – an architecture for publication of a global cellular space where each cell has a URI. This new approach will allow comparison, reproduction and the reuse of models and data. However, in order to succeed, this proposal requires participation, partnerships and investments. The main purpose of this paper is to present the architecture, benefi ts and challenges for debating with the scientific community

Um estudo exploratório dos games para introdução ao pensamento computacional

Published in Hipermídia e interdisciplinaridade na geração de conhecimento. 1ed., 2015

Nos últimos anos, tem crescido o interesse na utilização de games e seus mecanismos para o ensino e aprendizado, principalmente do pensamento computacional. Entretanto, apesar da existência de um volume expressivo de games constata-se uma lacuna quanto as pesquisas que os analisem sistematicamente. Esse tipo de pesquisa é relevante, pois pode apoiar a escolha de um determinado game por educadores e alunos, além de identificar possíveis limitações nos trabalhos recentes da literatura. Assim, o presente artigo objetiva identificar e analisar os games empregados para o ensino e aprendizado do pensamento computacional. O estudo levará em consideração algumas dimensões, como o gênero, habilidades computacionais exploradas e a linguagem utilizada.

Regional Scale Agent Based Modelling Of Land Change: Evolving Institutional Arrangements In Frontier Areas

Published in Thesis - Instituto Nacional de Pesquisas Espaciais, 2012

This thesis discusses the use of agent-based models for capturing land change in large frontier areas. Applying agent models in such areas is not straightforward, given the lack of data. To date, most agent based models of land frontiers study local areas using in-situ information. At regional scales, agent-based modellers need additional ways to describe collective decision-making. The work presents two ideas to deal with the complexities of agent-based models at such scales: institutional arrangements and states. Institutional arrangements help to model multi-agent interaction by explaining why, although there are rules and norms for land use, these rules are not always followed. This formalism captures states and transitions of agents in a simulation and helps to build expressive models, where the agent strategies evolve depending of local and external factors. We validate our ideas by building a deforestation model in an area of 60,000 km2 in Amazonia. Results show that we need to set different arrangements to capture changes in agents’ behaviour, as they react to external conditions. Thus, combining the ideas of institutional arrangements and states improves the explanatory power of agent models for regional scales.

Extracting the evolution of land cover objects from remote sensing image series

Published in Geoinformatik 2011. Munster, Germany, 2011

We live in a changing world and this acceleration of changes provides a strong motivation for research in GeoInformatics. Our tools and methods for representing and handling land cover data should be capable of dealing with change. Int this work we developed a land cover model to handle the evolution of land cover objects. This consist of an abstract data type and uses a limited number of spatial operations such as create and split to elict the changes is suffers in time. We present an application of the model to the data provide by Brazilian Amazon Deforestation Monitoring Program.

Dynamical coupling of multiscale land change models

Published in Landscape Ecology, 2009

No single model or scale can fully capture the causes of land change. For a given region, land changes may have different impacts at different places. Limits and opportunities imposed by biophysical and socio-economic conditions, such as local policies and accessibility, may induce distinct land change trajectories. These local land change trajecto- ries may, in turn, indirectly affect other places, as local actions interact with higher-level driving forces. Such intraregional interdependencies cannot be captured by studies at a single scale, calling for multiscale

Spatial relations across scales in land change models

Published in , 2007

Land changes are the result of a complex web of interaction between human and biophysical factors, which act over a wide range of temporal and spatial scales. In this paper we conceptualize spatial relations among geographic objects at different scales. We analyze two types of spatial relations: hierarchical, which handles the interaction of nested objects at different scales (countries, states and municipalities, for example); and a network-based relation, which handles action-at-a-distance types of interaction (market chains, for instance) of objects at different scales (such as farms in Central Amazonia to soybean market consumers at the global scale). We implemented such relations in the Terralib environment, in which they can be constructed using selected strategies, and then used in dynamic models. We exemplify the use of such concepts in a real-world case study in the Brazilian Amazonia. We conclude that combining hierarchical and network-based spatial relations provide a comprehensive conceptual framework to include top-down and bottom-up interactions and feedbacks in multi-scale land- change models.

Migrating geoprocessing routines to web services for water resource management applications

Published in 10th AGILE International Conference on Geographic Information Science, 2007, Aalborg, Dinamarca., 2007

Spatial data infrastructures are beginning to support the most common requirements of spatial information users—discovery, access, and visual overlay of datasets– however specialized users such as hydrological scientists require more advanced services for capturing, analyzing and processing huge volumes of data. To help migrate these scientists from desktop GIS to on-line service-data offers, we describe an approach to model and develop distributed geoprocessing services for water resource management applications built on top of basic SDI functionality.. We illustrate a GMES- funded scenario for predicting runoff in Alpine basins employing a framework which may serve to easily extrapolate our experiences to other specialized application fields like environmental and climate change applications.

TerraHS: Integration of Functional Programming and Spatial Databases for GIS Application Development

Published in Advances in Geoinformatics. 1ed. , 2007

Recently, researchers in GIScience argued about the benefits on using functional programming for geospatial application development and prototyping of novel ideas. This paper presents an application that interfaces a functional language with a spatial database. It enables developing GIS applications development in a functional language, while handling data are in a spatial database. We used this application develop a Map Algebra, that shows the benefits on using this paradigm in GIScience. Our work shows there are many gains in using a functional language, especially Haskell, to write concise and expressive GIS applications. The TerraHS application allows a good compromise between the expressive power of a functional language, and the data handling facilities of an imperative language.
