GIS Remote Sensing
The Expansive World Of Remote Sensing
Remote sensing is the practice of gathering information about Earth and its various elements—without touching them. While the method is indispensable across Earth science disciplines like geology, oceanography, and ecology, it also has vast applications in military, commercial, and humanitarian sectors.
Active Vs Passive: The Two Sides Of The Coin
Remote sensing techniques are generally classified into two categories: active and passive. In active remote sensing, signals are emitted to the object under study and the reflections are captured. Passive remote sensing, on the other hand, relies on natural light reflections to gather data.
Diverse Applications: More Than Just Geography
While geography and geophysics often take center stage, remote sensing has a broader scope. It plays a critical role in hydrology, exploration geophysics, and even in economic planning. In military applications, remote sensing is vital for intelligence gathering and strategic planning.
The Future Is Now: Advances In Technology
The introduction of advanced sensor technologies has expanded the possibilities of remote sensing. From high-resolution satellite imaging to airborne LiDAR, the field is continuously evolving, offering more precise and comprehensive data than ever before.
