Semantic search for earth observartion products using ontology services

Access to Earth Observation products remains difficult for end users in most domains. Although various search engines have been developed, they neither satisfy the needs of scientific communities for advanced search of EO products, nor do they use standardized vocabularies reusable from other organizations. To address this, we present the Prod-Trees platform, a semantically-enabled search engine for EO products enhanced with EO-netCDF, a new standard for accessing Earth Observation products.
