Tetherless World Constellation
Scientists – actually ANYONE - should be able to access and use a global, distributed knowledge base of scientific data that:
But… data and information is obtained by multiple means (instruments, models, analysis) using various (often opaque) protocols, in differing vocabularies, using (sometimes unstated) assumptions, with inconsistent (or non-existent) meta-data. It may be inconsistent, incomplete, evolving, and distributed AND created in a form that facilitates generation, not use (except by accident)
And … significant levels of semantic heterogeneity, large-scale data, complex data types, legacy systems, inflexible and unsustainable implementation technology…

Correlation maps for Jan 1 – 16, 2008
Impact:Throw your hands up in the air and just walk away, silently…
MODIS Aqua vs. MODIS Terra
Known Issues: The difference of EQCT and Day Time Node, modulated by data-day definition, caused the included overpass time difference, which makes the artifact difference. See sample images:
