Formalizing Spatiotemporal Knowledge In Remote Sensing Applications To Improve Image Interpretation, Christelle Pierkot, Samuel Andrés, Jean François Faure, Frédérique Seyler Dec 2013

Formalizing Spatiotemporal Knowledge In Remote Sensing Applications To Improve Image Interpretation, Christelle Pierkot, Samuel Andrés, Jean François Faure, Frédérique Seyler

Journal of Spatial Information Science

Technological tools allow the generation of large volumes of data. For example satellite images aid in the study of spatiotemporal phenomena in a range of disciplines such as urban planning environmental sciences and health care. Thus remote-sensing experts must handle various and complex image sets for their interpretations. The GIS community has undertaken significant work in describing spatiotemporal features and standard specifications nowadays provide design foundations for GIS software and spatial databases. We argue that this spatiotemporal knowledge and expertise would provide invaluable support for the field of image interpretation. As a result we propose a high level conceptual framework …

Multi-Scale Window Specification Over Streaming Trajectories, Kostas Patroumpas Dec 2013

Multi-Scale Window Specification Over Streaming Trajectories, Kostas Patroumpas

Journal of Spatial Information Science

Enormous amounts of positional information are collected by monitoring applications in domains such as fleet management cargo transport wildlife protection etc. With the advent of modern location-based services processing such data mostly focuses on providing real-time response to a variety of user requests in continuous and scalable fashion. An important class of such queries concerns evolving trajectories that continuously trace the streaming locations of moving objects like GPS-equipped vehicles commodities with RFID's people with smartphones etc. In this work we propose an advanced windowing operator that enables online incremental examination of recent motion paths at multiple resolutions for numerous point …

The Semantic Similarity Ensemble, Andrea Ballatore, Michela Bertolotto, David C. Wilson Dec 2013

The Semantic Similarity Ensemble, Andrea Ballatore, Michela Bertolotto, David C. Wilson

Journal of Spatial Information Science

Computational measures of semantic similarity between geographic terms provide valuable support across geographic information retrieval data mining and information integration. To date a wide variety of approaches to geo-semantic similarity have been devised. A judgment of similarity is not intrinsically right or wrong but obtains a certain degree of cognitive plausibility depending on how closely it mimics human behavior. Thus selecting the most appropriate measure for a specific task is a significant challenge. To address this issue we make an analogy between computational similarity measures and soliciting domain expert opinions which incorporate a subjective set of beliefs perceptions hypotheses and …

Testing Ogc Web Feature And Coverage Service Performance: Towards Efficient Delivery Of Geospatial Data, Gregory Giuliani, Alain Dubois, Pierre Lacroix Dec 2013

Testing Ogc Web Feature And Coverage Service Performance: Towards Efficient Delivery Of Geospatial Data, Gregory Giuliani, Alain Dubois, Pierre Lacroix

Journal of Spatial Information Science

OGC Web Feature Service (WFS) and Web Coverage Service (WCS) specifications allow interoperable access to distributed geospatial data made available through spatial data infrastructures (SDIs). To ensure that a service is sufficiently responsive to fulfill users’ expectations and requirements performance of services must be measured and monitored to track latencies bottlenecks and errors that may negatively influence its over- all quality. Despite the importance of data retrieval and access little research has been published on this topic and mostly concentrates on the usability of services when integrating distributed data sources. Considering these issues this paper extends and validates the FOSS4G …

Using Trend Clusters For Spatiotemporal Interpolation Of Missing Data In A Sensor Network, Annalisa Appice, Anna Ciampi, Donato Malerba, Pietro Guccione Jun 2013

Using Trend Clusters For Spatiotemporal Interpolation Of Missing Data In A Sensor Network, Annalisa Appice, Anna Ciampi, Donato Malerba, Pietro Guccione

Journal of Spatial Information Science

Ubiquitous sensor stations continuously measure several geophysical fields over large zones and long (potentially unbounded) periods of time. However observations can never cover every location nor every time. In addition due to its huge volume the data produced cannot be entirely recorded for future analysis. In this scenario interpolation i.e. the estimation of unknown data in each location or time of interest can be used to supplement station records. Although in GIScience there has been a tendency to treat space and time separately integrating space and time could yield better results than treating them separately when interpolating geophysical fields. According …

A Dynamic And Context-Aware Semantic Mediation Service For Discovering And Fusion Of Heterogeneous Sensor Data, Mohamed Bakillah, Steve H. L. Liang, Alexander Zipf, Mir Abolfazl Mostafavi Jun 2013

A Dynamic And Context-Aware Semantic Mediation Service For Discovering And Fusion Of Heterogeneous Sensor Data, Mohamed Bakillah, Steve H. L. Liang, Alexander Zipf, Mir Abolfazl Mostafavi

Journal of Spatial Information Science

Sensors play an increasingly critical role in capturing and distributing observations of phenomena in our environment. The vision of the semantic sensor web is to enable the interoperability of various applications that use sensor data provided by semantically heterogeneous sensor services. However, several challenges still need to be addressed to achieve this vision. More particularly, mechanisms that can support context-aware semantic mapping and that can adapt to the dynamic metadata of sensors are required. Semantic mapping for the sensor web is required to support sensor data fusion, sensor data discovery and retrieval, and automatic semantic annotation, to name only a …

Interactive Maps: What We Know And What We Need To Know, Robert E. Roth Jun 2013

Interactive Maps: What We Know And What We Need To Know, Robert E. Roth

Journal of Spatial Information Science

This article provides a review of the current state of science regarding cartographic interaction a complement to the traditional focus within cartography on cartographic representation. Cartographic interaction is defined as the dialog between a human and map mediated through a computing device and is essential to the research into interactive cartography geovisualization and geovisual analytics. The review is structured around six fundamental questions facing a science of cartographic interaction: (1) what is cartographic interaction (e.g. digital versus analog interactions interaction versus interfaces stages of interaction interactive maps versus mapping systems versus map mash-ups); (2) why provide cartographic interaction (e.g. visual …

Automatic Integration Of Spatial Data In Viewing Services, Ara Tooamnian, Lars Harrie, Ali Mansourian, Petter Pilesjö Jun 2013

Automatic Integration Of Spatial Data In Viewing Services, Ara Tooamnian, Lars Harrie, Ali Mansourian, Petter Pilesjö

Journal of Spatial Information Science

Geoportals are increasingly used for searching viewing and downloading spatial data. This study concerns methods to improve the visual presentation in viewing services. When spatial data in a viewing service are taken from more than one source there are often syntactic semantic topological and geometrical conflicts that prevent maps being fully consistent. In this study we extend a standard view service with methods to solve these conflicts. The methods are based on: (1) semantic labels of data in basic services (2) a rule-base in the portal layer and (3) integration methods in the portal layer. To evaluate the methodology we …

Mining Sensor Datasets With Spatiotemporal Neighborhoods, Michael Patrick Mcguire, Vandana Janeja, Aryya Gangopadhyay Jun 2013

Mining Sensor Datasets With Spatiotemporal Neighborhoods, Michael Patrick Mcguire, Vandana Janeja, Aryya Gangopadhyay

Journal of Spatial Information Science

Many spatiotemporal data mining methods are dependent on how relationships between a spatiotemporal unit and its neighbors are defined. These relationships are often termed the neighborhood of a spatiotemporal object. The focus of this paper is the discovery of spatiotemporal neighborhoods to find automatically spatiotemporal sub-regions in a sensor dataset. This research is motivated by the need to characterize large sensor datasets like those found in oceanographic and meteorological research. The approach presented in this paper finds spatiotemporal neighborhoods in sensor datasets by combining an agglomerative method to create temporal intervals and a graph-based method to find spatial neighborhoods within …
