Validation practices for satellite-based Earth observation data across communities

Modeling Earth Observation Satellite Data Semantically

This paper presents preliminary research results on using semantic technologies to model Earth observation satellite data. The research goal is to enhance the data search functionalities that satellite data catalogues provide to researchers and practitioners. An ontology that captures characteristics of satellite data is introduced. How to utilize this ontology in assisting data search and how ...

Satellite earth observation in operational oceanography

The role and contribution of satellite data in operational oceanography is reviewed, with emphasis on northern European seas. The possibility to observe various ocean parameters and processes by existing satellite sensors, such as optical instruments, infrared radiometers, passive Ž . microwave radiometers, and active microwave systems altimeter, scatterometer, SAR is discussed. The basic param...

Monte Carlo Based Non-Linear Mixture Model of Earth Observation Satellite Imagery Pixel Data

Monte Carlo based non-linear mixel (mixed pixel) model of visible to near infrared radiometer of earth observation satellite imagery is proposed. Through comparative studies with actual real earth observation satellite imagery data between conventional linear mixel model and the proposed non-linear mixel model, it is found that the proposed mixel model represents the pixels in concern much prec...

Facilitating Health Data Sharing Across Diverse Practices and Communities

Health data sharing with and among practices is a method for engaging rural and underserved populations, often with strong histories of marginalization, in health research. The Institute of Translational Health Sciences, funded by a National Institutes of Health Clinical and Translational Science Award, is engaged in the LC Data QUEST project to build practice and community based research netwo...
