L'analyse fractale, un nouvel outil pour l'analyse spatiale des agglomérations urbaines
1997
The fractal approach. A new tool for the spatial analysis of urban agglomerations. Fractal geometry is a new approach for the study of spatial distributions. The basic model is a law of hierarchical distribution corresponding to Pareto's law which is familiar to urban geographers and demographers. The methods of fractal analysis can be used to study the spatial organization of human activities across scales. The regularities and the discontinuities in the distributions can then be identified. These discontinuities can be spatially situated. Applying this concept to urbanized areas has shown that districts can be defined and classified according to their scaling relations, thereby allowing d…
Telerilevamento e GIS per la valutazione e il monitoraggio delle isole di calore in ambiente urbano
2017
The techniques of spatial analysis and Remote Sensing represent an useful tool for the knowledge and the study of the Urban Heat Island phenomenon (English acronym UHI). In this study, among the different causes that lead to the generation of the event, those regarding physical features of the surface and the presence of different land use/cover such as: the high cover of urban areas and the lack of green areas have been examined. The Remote Sensing techniques allow to create maps of the land use/cover, then, in order to estimate the different in temperature due to the distance to the vegetation, the temperature of the bodies already tested have been compared with a thermal map. In detail t…
Proposition of Convolutional Neural Network Based System for Skin Cancer Detection
2019
Skin cancer automated diagnosis tools play a vital role in timely screening, helping dermatologists focus on melanoma cases. Best arts on automated melanoma screening use deep learning-based approaches, especially deep convolutional neural networks (CNN) to improve performances. Because of the large number of parameters that could be involved during training in CNN many training samples are needed to avoid overfitting problem. Gabor filtering can efficiently extract spatial information including edges and textures, which may reduce the features extraction burden to CNN. In this paper, we proposed a Gabor Convolutional Network (GCN) model to improve the performance of automated diagnosis of …
Monitoring water and carbon fluxes at fine spatial scales using HyspIRI-like measurements
2012
Remotely sensed observations in the visible to the shortwave infrared (VSWIR) and thermal infrared (TIR) regions of the electromagnetic spectrum can be used synergistically to provide valuable products of land surface properties for reliable assessments of carbon and water fluxes. The high spatial, spectral and temporal resolution VSWIR and TIR observations provided by the proposed Hyperspectral - InfraRed (HyspIRI) mission will enable a new era of global agricultural monitoring, critical for addressing growing issues of food insecurity. To enable predictions at fine spatial resolution (<100m), modeling efforts must rely on a combination of high-frequency temporal and highresolution spa…
Exporatory data analysis of environmental governance at local level in the south -west region of Poland
2018
Prowadzenie zintegrowanych działań w ramach zrównoważonego rozwoju wymaga obiektywnego rozpoznania potrzeb ich wdrażania na podstawie wyników kompleksowych analiz wielu złożonych, powiązanych ze sobą czynników odzwierciedlających stan środowiska przyrodniczego i sytuację ekonomiczno-demograficzną. Wzrastająca funkcjonalność Systemów Informacji Geograficznej (GIS) spowodowała, że bazy danych GIS stały się narzędziem wspierającym implementację działań z zakresu zrównoważonego rozwoju. Celem pracy było rozpoznanie zmienności przestrzennej poziomu ładu środowiskowego w południowo-zachodnim regionie Polski. Zastosowano metody badań z zakresu wielowymiarowych technik eksploracji danych i analizy …
Spatial Diversity of Environmental Governance in the Aspect of Sustainable Development of the Polish-Czech Border Area
2018
The current action plan for implementing sustainable development is the “Agenda for Sustainable Development 2030” includes the goals which determine the three dimensions of sustainable development, i.e. economic, social and environmental. Dynamically developing Geographic Information Systems (GIS) and widespread availability of spatial information resources are analytical tools supporting the monitoring and implementation of these objectives and are widely applicable in this research area. The aim of the study was to determine the spatial diversity of the environmental governance level and its components in the following areas: climate change, energy, air protection, land use, biodiversity …

Fuzzy Systems Based on Multispecies PSO Method in Spatial Analysis
2012
We present a method by using the hierarchical cluster-based Multispecies particle swarm optimization to generate a fuzzy system of Takagi-Sugeno-Kang type encapsulated in a geographical information system considered as environmental decision support for spatial analysis. We consider a spatial area partitioned in subzones: the data measured in each subzone are used to extract a fuzzy rule set of above mentioned type. We adopt a similarity index (greater than a specific threshold) for comparing fuzzy systems generated for adjacent subzones.
