We present a new approach for linking heterogeneous data of the same objective nature, such as 2D maps, 3D virtual environments and videos with GPS data. We have identified three key challenges (georeferencing, content creation for geospatial videos and bidirectional linking) that should be addressed to link among geographic hypermedia. We propose an easily implementable data model that serves ...

We propose a data driven approach to detect zebra crossings in aerial imagery. The system automatically learns an appearance model from available geospatial data for an examined region. HOG as well as LBPH features, in combination with a SVM, yield state of the art detection results on different datasets. We also use this classifier across datasets obtained from different countries, to facilita...

A geospatial catalogue service provides a network-based meta-information repository and interface for advertising and discovering shared geospatial data and services. Descriptive information (i.e., metadata) for geospatial data and services is structured and organized in catalogue services. The approaches currently available for searching and using that information are often inadequate. Semanti...

An Integrated Earth Sensing demands seamless access to large-scale geospatial data gathered by remote sensing and in-situ sensor network deployments. To that end, the Global Earth Observation (GEO) Grid provides a framework for sharing a wide array of scientific information such as satellite data, geologic maps, and insitu sensing data in a standards-compliant manner. In this paper, we describe...

Huge volumes of geospatial data have been collected by both public and private sectors. In order for the geospatial data to be useful, information has to be extracted from the data and converted to knowledge. However, currently it is very difficult for most of users to obtain the geospatial data and to turn them into useful information and knowledge. In order for geospatial information and know...

It is often desirable to consider an object’s movement over space and time from the perspective of different levels of detail or granularity. Changing to a more detailed view uncovers information that otherwise is unknown. Conversely, moving to a simpler view can improve our understanding of the movement patterns of an object. This paper considers shifts in granularity over geospatial lifelines...

Technically the spatial non-interoperability problem associated with current geospatial processing systems can be categorized as data and access non-interoperability. In GIS community, Open GIS Consortium (OGC) geospatial Web services have been introduced to overcome spatial noninteroperability problem associated with most geospatial processing systems. At the same time, in Information Technolo...
