Big Earth Observation Data Analytics

Gilberto Ribeiro de Queiroz, Rolf Simões, Vitor Gomes
Image Processing Division, DPI - National Institute for Space Research, INPE, Brazil

There has been a significant recent effort to develop methods to analyse big Earth observation data and build databases for large image sets. The new big EO data sets allow researchers to analyse dense time series of satellite data and then use the results to describe how changes happen. This tutorial will describe recent results on methods for management and analysis of large EO data sets. We will discuss data store in array databases, web services for big EO data, and machine learning methods for land use and land cover classification of satellite image time series. The course will use a hands-on approach, with examples and applications developed in the R open source environment.

Challenges in Urban Computing

Clodoveu A. Davis Jr
Computer Science Department - Federal University of Minas Gerais, Brazil

In the days of urban GIS projects, in the early nineties, there was much discussion about data conversion and geographic database creation. There was the need to adequately represent components of the many systems that compose a modern city. Actors such as the local government and utility companies were predominant in these efforts, which pioneered the integration of geographic information to corporate systems.
Current discussions on the importance of cities and on the need to improve their internal systems take for granted the wide availability of basic GIS data. There is now the need to explore new (and big) sources of data, such as environmental sensors and mobile devices. Crowdsourcing and crowdsensing are an integral part of this scenario, either using volunteered contributions or passive data extraction from social networks, regardless of bias and coverage deficiencies.
Urban computing connects all types of sensing technologies and methods to advanced data management and analysis, in order to tackle the main issues that cities face, seeking more efficient urban systems, and measuring impact in terms of improved quality of life for citizens. Through urban computing problems, Computer Science achievements and advancements in areas such as data integration, management, and analytics are put to the test, when faced with a continuous set of complex situations and the need for quick responses to problems.
The talk discusses the numerous challenges that present themselves for the advancement of urban computing. A special attention is given to particular problems faced by Brazilian cities, regarding data availability and integration.
