Geospatial Data / Remote Sensing Tutorial
Remote Sensing Principles
This section of the tutorial covers basic concepts related
to remote sensing. The information we provide here will help you become
familiar enough with remote sensing concepts to begin to use the Landsat
data and to embark on a more in-depth exploration of the vast field of
remote sensing. The primary topics in this section are listed below and
in the menu on the left.
Although we cannot cover every aspect of remote sensing in these pages,
this information will help you understand just what a remotely sensed
image is and how the data can be useful. Whenever you discover that you
want more information on a particular item, go to any of the resources
we list on various pages of this site, or go to the resources
page of the tutorial. A variety of textbooks, courses, and on-line resources
offer comprehensive coverage of remote sensing.
After reading the "Remote Sensing Principles" pages, you can
find a description of the data products from Landsat 7 that are available
from this web site in the section entitled Landsat
7 Data Products.
