Approaches to establishing a metadata standard for field spectroscopy datasets

Abstract

There is an urgent need within the international remote sensing community to establish a metadata standard for field spectroscopy that ensures high quality, interoperable metadata sets that can be archived and shared efficiently within Earth observation data sharing systems. Careful examination of all stages of metadata collection and analysis can inform a robust standard that is applicable to a range of field campaigns. This paper presents approaches towards a standard that encompasses in situ metadata collection and initiatives towards sharing metadata within intelligent archiving systems.

Assessing Field Spectroscopy Metadata Quality

“…There is no standardized methodology for documentation of field spectroscopy data or metadata [1][2][3][4][5]. The need for a standardized methodology for collecting-and assuring the quality of-field spectroscopy metadata has increased with the emergence of data sharing initiatives such as NASA's EOSDIS (Earth Science Data and Information System), the LTER (Long Term Ecological Research) network, the Australian Terrestrial Ecosystem Research Network (TERN), SpecNet [6] and some of the smaller ad hoc spectral libraries and databases created by remote sensing communities internationally.…”
