Figure 5-27. Radarsat image, pixel resolution equals 10 m. Image is centered over
the Illinois River (upper left), Mississippi River (large channel in center), and the
Missouri River (smaller channel in center. Chapter 6 case study 3 details the
analysis of this scene. Taken from Tracy (2003).
g. Customized Spectral Library. Many software programs allow users to build
and maintain a customized spectral library. This is done by importing spectra sig-
natures from objects of interest and can be applied to identify unknown objects in
an image.
h. Internal Programming.
(1) Image processing software allows users to develop computing tech-
niques and unique image displays by programming from within the software
package. Programming gives the user flexibility in image manipulation and in-
formation extraction. The users' manual and online help menus are the best re-
sources for information on how to program within particular software.
(2) New applications in image processing and analysis are rapidly being
developed and incorporated into the field of remote sensing. Other advanced uses
in image processing include the modification of standard methods to meet indi-
vidual project needs and improving calibration methods. Go to
