Remote Sensing, Uncertainty Quantification and a Theory of Data Systems Workshop: February 12-14, 2018

**Attendance by invitation only**

Location

This workshop will be held at the California Institute of Technology (Caltech)

Description

This Workshop invites statisticians, applied mathematicians, computer scientists, experts in remote sensing technology, and Climate and Earth System scientists to convene to review, discuss, and plan research on issues related to large-scale, efficient analysis of distributed data using spatial statistical methods. Remote sensing data are natural inputs to spatial statistical algorithms, but in many cases data are massive, and are stored in different physical locations. These data must be brought together in some way in order to estimate spatial covariance functions, but moving data to a central location for analysis is tedious at best and impossible at worst. Some remote data reduction is almost certainly necessary, but how much? What are the consequences for inference? The fundamental issue underlying these questions is how to navigate the trade-space between computational and transmission costs versus uncertainty in the estimates or inferences that are ultimately produced. The Workshop will be organized around the following themes:

  • Data systems and their architectures especially at NASA and NOAA
  • Multi-layer network models for data systems
  • The computational–statistical trade-off: theory and application
  • Spatial statistics with distributed data
  • Case study problems with uncertainty requirements and cost limitations
