3D Building Change Detection on the basis of Airborne Laser Scanning Data
AGILE Digital Editions (2014-06)The paper presents the possibility to use airborne laser scanning (ALS) for building change detection. For the analysis data was gathered during two campaigns: 2003 and 2011. As research area we chose a test site covering ... -
A comparative study on VGI and professional noise data
AGILE Digital Editions (2014-06)The ubiquitous nature of mobile devices and its growing presence in urban areas, turn them up into low cost environmental monitoring platforms. In this field, several authors made different efforts to provide alternatives ... -
A conceptual representation for modelling the synchronization process of complex road networks
AGILE Digital Editions (2014-06) -
A flexible framework for assessing the quality of crowdsourced data
AGILE Digital Editions (2014-06)Crowdsourcing as a means of data collection has produced previously unavailable data assets and enriched existing ones, but its quality can be highly variable. This presents several challenges to potential end users that ... -
A geometric configuration ontology to support spatial querying
AGILE Digital Editions (2014-06)A number of ontologies of spatial relations have been defined in the literature, but most of these are either confined to a small subset of relations, or focussed on language expressions, and not specified geometrically. ... -
A Heuristic Based on the Intrinsic Dimensionality for Reducing the Number of Cyclic DTW Comparisons in Shape Classification and Retrieval Using AESA
Springer Berlin Heidelberg (2012)Cyclic Dynamic Time Warping (CDTW) is a good dissimilarity of shape descriptors of high dimensionality based on contours, but it is computationally expensive. For this reason, to perform recognition tasks, a method to ... -
A Spatial Approach to Surveying Crime‐problematic Areas at the Street Level
AGILE Digital Editions (2014-06)Reaching far beyond the realm of geography and its related disciplines, spatial analysis and visualization tools now actively support the decision-making processes of law enforcement agencies. Interactive mapping of crime ... -
Agile access to sensor network
AGILE Digital Editions (2014-06)The work in this paper aims at increasing the interoperability and improving accessibility of data provided by sensor networks. This way, this data can be employed by different devices and with diverse context requirements, ... -
An algorithm for segmenting a feature set into equitable regions
AGILE Digital Editions (2014-06)A set of geographic features of the same class representing a geographic area is often required to be divided in to several subsets/regions so that the sum of a numeric attribute of the features in each subset/region ... -
Analysing spatiotemporal patterns of antibiotics prescriptions
AGILE Digital Editions (2014-06)The emergence of antibiotic resistances due to antibiotic residues in urban sewage systems is becoming an increasingly important issue. This paper presents a model for the spatiotemporal analysis of antibiotic inputs to ... -
Applying a CA-based model to explore land-use policy scenarios to contain sprawl in Thessaloniki, Greece
AGILE Digital Editions (2014-06)This study addresses the issue of urban sprawl through the application of a Cellular Automata (CA) based model in the area of Thessaloniki, Greece. To link macro-scale to micro-dynamic processes the model integrates a ... -
Assessment of Financial Risk Prediction Models with Multi-criteria Decision Making Methods
Springer Berlin Heidelberg (2012)A wide range of classification models have been explored for financial risk prediction, but conclusions on which technique behaves better may vary when different performance evaluation measures are employed. Accordingly, ... -
Assessment of the integration of geographic information in e-government policy in Europe
AGILE Digital Editions (2014-06)The integration of geographic information and services in a broader e-government context can be considered as a necessary condition for realising the full potential of Spatial Data Infrastructures (SDIs). In recent years, ... -
Augmented reality and GIS: On the possibilities and limits of markerless AR
AGILE Digital Editions (2014-06)The application of Augmented Reality (AR) in the geo-spatial domain offers huge potentials: AR can visualize invisible properties of spatial entities, can display historic data for them, or can help in finding places. ... -
Cadastral data integration through Linked Data
AGILE Digital Editions (2014-06)Cadastral data is one of the more important types of geospatial data. Taking into account the importance of these data, several international bodies have worked for creating a standardised model for land administration. ... -
Capability of movementfeatures extracted fromGPS trajectoriesforthe classification of fine‐grained behaviors
AGILE Digital Editions (2014-06)Recent advances in tracking technologies provide an unprecedented opportunity for a better understanding of animal movement. Data from multiple sensors can be used to capture crucial factors deriving the behaviors of the ... -
Characteristics of Citizen-contributed Geographic Information
AGILE Digital Editions (2014-06)Current Internet applications have been increasingly incorporating citizen-contributed geographic information (CCGI) with much heterogeneous characteristics. Nevertheless, despite their differences, several terms are often ... -
Combining Probabilistic Language Models for Aspect-Based Sentiment Retrieval
Springer Berlin Heidelberg (2012)In this paper, we present a new methodology aimed at retrieving relevant product aspects from a collection of customer reviews, as well as the most salient sentiments expressed about them. Our proposal is both unsupervised ... -
