  3. Quiz Is it a kind of Remote Sensing?

  4. 1 Definition • Remote Sensing is : • - “The art and science of obtaining information about an object without being in direct contact with the object” (Jensen 2000). • - There is a medium of transmission involved.

  5. 2-1 Advantages Improved vertical vantage point of view Historical record Comparability of data Rapid data collection Cost savings Possibility of obtaining data from inaccessible regions Bird’s eye view

  6. 2-2 Disadvantages • Expensive to build and operate • Resolution is often coarse. • Data interpretation can be difficult. • Human phenomena can’t be extracted.

  7. Which is nottrue about advantage of Remote Sensing? Q. ① vertical vantage point of view ② obtaining data from inaccessible regions ③ extracting Human phenomena ④ cheap method of acquiring information ⑤ historical record ? ③ extracting Human phenomena
