1 LECTURE NOTES ON REMOTE SENSING AND GIS (A70140) IV B. Tech I Semester (JNTUH-R15) By Mr. Y. Ravi Kumar Assistant Professor DEPARTMENT OF CIVIL ENGINEERING INSTITUTE OF AERONAUTICAL ENGINEERING (Autonomous) DUNDIGAL, HYDERABAD - 500 043 2 UNIT-1 PHOTOGRAMMETRY Photogrammetry is the science of making measurements from photographs, especially for recovering the exact positions of surface points. Moreover, it may be used to recover the motion pathways of designated reference points located on any moving object, on its components and in the immediately adjacent environment.
4. Passive/ Active Remote Sensing Depending on the source of electromagnetic energy, remote sensing can be classified as passive or active remote sensing. In the case of passive remote sensing, source of energy is that naturally available such as the Sun. Most of the remote sensing systems work in passive mode using solar energy as the source of
