what is geoscience
What is a Geoscientist? What Does a Geoscientist Do? Geoscience is the study of the earth's history and how it functions and interacts with the surrounding biospheres. Geoscientists study the earth's many different facets, including its geological composition, processes, and history.
GIScience is variously defined as the science behind the systems; the set of fundamental questions raised by GIS; the research field that will define the next generation of GIS; the body of knowledge that GIS implements; and the use of GIS as a tool for scientific research.
