Tutorial: Introduction to Remote Sensing of Environment

You can print or read this booklet in color from MicroImages' Web site. The Web site is also your source for the newest tutorial booklets on other topics. You can download an installation guide, sample data, and the latest version of TNTmips. Imagery acquired by airborne or satellite sensors provides an important source of information for mapping and monitoring the natural and manmade features on the land surface. Interpretation and analysis of remotely sensed imagery requires an understanding of the processes that determine the relationships between the property the sensor actually measures and the surface properties we are interested in identifying and studying. Knowledge of these relationships is a prerequisite for appropriate processing and interpretation. This booklet presents a brief overview of the major fundamental concepts related to remote sensing of environmental features on the land surface. Sample Data The illustrations in this booklet show many examples of remote sensing imagery. You can find many additional examples of imagery in the sample data that is distributed with the TNT products. If you do not have access to a TNT products CD, you can download the data from MicroImages' Web site. In particular , the CB_DATA, SF_DATA, BEREA, and COMBRAST data collections include sample files with remote sensing imagery that you can view and study. More Documentation This booklet is intended only as an introduction to basic concepts governing the acquisition, processing, and interpretation of remote sensing imagery. You can view all types of imagery in TNTmips using the standard Display process, which is introduced in the tutorial booklet entitled Displaying Geospatial Data. Many other processes in TNTmips can be used to process, enhance, or analyze imagery. Some of the most important ones are mentioned on the appropriate pages in this booklet, along with a reference to an accompanying tutorial booklet. TNTmips ® Pro and TNTmips Free TNTmips (the Map and Image Processing System) comes in three versions: the professional version of TNTmips (TNTmips Pro), the low-cost TNTmips Basic version, and the TNTmips Free version. All versions run exactly the same code from the TNT products DVD and have nearly the same features. If you did not purchase the professional version (which requires a software license key) or TNTmips Basic, then TNTmips operates in TNTmips Free mode. Remote sensing is the science of obtaining and interpreting information from a distance, using sensors that are not in physical contact with the object …
