New generation remote sensing technologies open today new application areas and demonstrate their effectiveness providing geo-information in support to disaster management. In the same time, new challenges can be identified and among them has a crucial role the validation of geo-information under the new specific constraints dictated by the disaster management application area. In the frame of ...

In this paper we present the research objectives and methodology for a running project of distributed web processing geo-services for spatio-temporal analysis of geo-data, the case of Lloyd’s lists. We introduce the current problems and discuss the solutions in means of theoretical and practical perspectives. Initial results from geo-data modeling using Unified Modeling Language (UML) is presen...

This paper describes our participation at GeoCLEF 2005. We detail the main software components of our Geo-IR system, its adaptation for GeoCLEF and the obtained results. The software architecture includes a geographic knowledge base, a text mining tool for geo-referencing documents, and a georanking component. Results show that geo-ranking is heavily dependent on the information in the knowledg...

Geospatial Information Technology (GIT) is being used in an increasing number of application fields and is relevant for more users than ever before. This diversity of applications and users raise questions about the relevance of different types of geo-representation (such as, maps, aerial photos, satellite imagery, 3D models) and their congruency with different user profiles. Studies have shown...

While inferring the geo-locations of web images has been widely studied, there is limited work engaging in geo-location inference of web videos due to inadequate labeled samples available for training. However, such a geographical localization functionality is of great importance to help existing video sharing websites provide location-aware services, such as location-based video browsing, vide...

The Gene Expression Omnibus (GEO) at the National Center for Biotechnology Information (NCBI) is the largest public repository for high-throughput gene expression data. Additionally, GEO hosts other categories of high-throughput functional genomic data, including those that examine genome copy number variations, chromatin structure, methylation status and transcription factor binding. These dat...

The ubiquity of low-cost GPS-enabled mobile devices and the proliferation of online social networks have enabled the collection of rich geo-social information that includes the whereabouts of the users and their social connections. This information can be used to provide a rich set of access control policies that ensure that resources are utilized uniquely and securely. Existing literature focu...

Combined processing using different sensor types, i.e. for applications like change detection, requires a good geo-referencing. Furthermore the individual sensor properties have to be taken into account. SAR systems are side-looking and run-time systems. They suffer from occlusions and ambiguities especially in urban areas. Additionally layover and shadow effects disturb the geo-referencing of ...
