The Brazilian urbanization process produced a complex urban space, with variety of land use and cover as result. study these forms through classification system is essential, but most current systems don’t capture this complexity, condensing it. Urban are difficult to distinguish classify, resulting in the need for high degree detail, more accurate planning. objective work propose cover, which ...

Whilst large scale noise-mapping techniques have been applied extensively in practice, as required by the EU Directive on environmental noise, they are often not applicable for microscale urban areas such as a street or a square. This talk will discuss a series of simulation techniques as well as related acoustic theories for accurately calculating the sound field for micro-scale urban areas. T...

Urban remote sensor geocomputation is at a crossroads. In one direction lie opportunities for developing models for detailed mapping of urban morphology from very high spatial resolution imagery; and in the other the possibility of creating broader integrative models that link spectra with functional variables for measuring urban growth and sustainability. The former overlaps with traditional p...

Urban green spaces provide important recreational services for urban residents. In general, when park visitors enjoy "the green," they are in actuality appreciating a mix of biotic, abiotic, and man-made park infrastructure elements and qualities. We argue that these three dimensions of structural diversity have an influence on how people use and value urban parks. We present a straightforward ...

Cities are highly dynamic entities, with urban elements such as businesses, cultural and social Points-ofInterests (POIs), housing, transportation and the like, continuously changing. In order to maintain accurate spatial information in these settings, crowd-sourcing models of data collection, such as in OpenStreetMap (OSM), have come under investigation. Like many crowd-sourcing platforms (e.g...

In this paper we present the design process and some interesting field t r ial r e sults o f t w o d i fferent game applications, designed and developed in order to extend and motivate the community of mPASS. mPASS is an urban accessibility mapping system that allows citizens to collect reliable data about barriers and facilities via crowdsourcing and crowdsensing and it uses these data to calc...

Terrestrial laser scanning is meanwhile frequently used to capture high quality 3D models of cultural heritage sites and historical buildings. However, the collection of dense point clouds can become very labor expensive, especially if larger areas like complete historic sections of a town have to be captured from multiple viewpoints. Such scenarios opt for vehicle based mobile mapping systems ...

This paper describes work-in-progress aimed at generating dense 3D maps of urban environments using laser range data acquired from a moving platform. These maps display both fine-scale detail (resolving features only a few centimeters across) and large-scale consistency (typical maps are approximately 0.5 km on a side). In this paper, we sketch a basic 3D mapping algorithm (paying particular at...

Noise mapping is an effective method of visualizing and accessing noise pollution. In this paper, a noise-mapping method based on smartphones to effectively and easily measure environmental noise is proposed. By using this method, a noise map of an entire area can be created using limited measurement data. To achieve the measurement with certain precision, a set of methods was designed to calib...
