Cornell's
Digital Earth
The Digital Earth Project, part of the Cornell Geoscience Information
System (GIS), is a global database created by the Institute for
the Study of the Continents (INSTOC) at Cornell to make accessible
geological information accumulated by Cornell researchers over the
last eight years. The GIS includes over 100 different data sets
on the structure of the Earth's crust, location of earthquake faults,
a record of earthquake and volcanic events, magnetic and gravity
measurements and descriptions of aquifers, along with details of
surface topography. Interactive tools allow users -- from advanced
researchers to elementary schoolchildren -- to create maps with
almost any selection and combination of the data.
Mineralogy database
This mineral database contains 4,442 individual
mineral species descriptions with links and a comprehensive image
library.
