چکیده
TELEIOS is a recent European project that addresses the need for scalable access to petabytes of Earth Observation data and the discovery of knowledge that can be used in applications. To achieve this, TELEIOS builds on scientific databases, linked geospatial data, ontologies, and techniques for discovering knowledge from satellite images and auxiliary data sets. In this paper we outline the knowledge discovery framework of TELEIOS and discuss how it can be used together with ontologies and linked geospatial data for the development of a Virtual Earth Observatory for TerraSAR-X data.

متن کاملBuilding Virtual Earth Observatories Using Ontologies and Linked Geospatial Data
Advances in remote sensing technologies have enabled public and commercial organizations to send an ever-increasing number of satellites in orbit around Earth. As a result, Earth Observation (EO) data has been constantly increasing in volume in the last few years, and is currently reaching petabytes in many satellite archives. For example, the multi-mission data archive of the TELEIOS partner G...

Advances in remote sensing technologies have allowed us to send an ever-increasing number of satellites in orbit around Earth. As a result, Earth Observation data archives have been constantly increasing in size in the last few years, and have become a valuable source of data for many scientific and application domains. When EO data is coupled with other data sources many pionner applications c...
متن کاملOntology-driven Automatic Geospatial-Processing Modeling based on Web-service Chaining
Earth System Science (ESS) research and applications often involve in collecting, analyzing and modeling with distributed heterogeneous geospatial data. Those data are processed step-by-step in geospatial analysis systems to extract information and knowledge products for applications and decision makings. Conceptually, such a step-by-step process forms a geospatial processing model that represe...
