Metadata of spectral data collections


Hueni, Andreas; Nieke, Jens; Schopfer, Jürg; Kneubühler, Mathias; Itten, Klaus I (2007). Metadata of spectral data collections. In: 5th Workshop on Imaging Spectroscopy, Bruges (B), 23 April 2007 - 25 April 2007.

Abstract

Metadata is important for the interpretation of scientific data, quality assessment and long term usability of data sets. The sharing of spectral data collections among research groups is uncommon and one of the reasons for this is the missing standardisation of the sampling process. Appropriate metadata serves the purpose of detailing the sampling procedure and the surrounding conditions during data capture, thus providing necessary information for data sharing. Reliable data retrieval requires the organised storage of spectral and metadata. To this means RSL developed the SPECCHIO system which is based on a relational database and provides data input, query and output mechanisms that strive to minimize the manual data capture. SPECCHIO serves as a non-redundant repository and source for spectral signatures which can be retrieved by metadata queries. The system will be used in the level 2/3 processing of the APEX (Airborne Prism Experiment) product generation to support the classification of natural and manmade materials and landcovers.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
