The first images from space were taken on the sub-orbital V-2 rocket flight launched by the US on October 24, 1946. Satellite image of Fortaleza.. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world.
Photo interpretation at the U.S. National Photographic Interpretation Center during the Cuban Missile Crisis. Aerial photographic and satellite image interpretation, or just image interpretation when in context, is the act of examining photographic images, particularly airborne and spaceborne, to identify objects and judging their significance.

In current usage, the term remote sensing generally refers to the use of satellite - or aircraft-based sensor technologies to detect and classify objects on Earth. It includes the surface and the atmosphere and oceans, based on propagated signals (e.g. electromagnetic radiation ).
A reconnaissance satellite or intelligence satellite (commonly, although unofficially, referred to as a spy satellite) is an Earth observation satellite or communications satellite deployed for military or intelligence applications. The first generation type (i.e., Corona [ 1][ 2] and Zenit) took photographs, then ejected canisters of ...
Imagery intelligence ( IMINT ), pronounced as either as Im-Int or I-Mint, is an intelligence gathering discipline wherein imagery is analyzed (or "exploited") to identify information of intelligence value. [ 1] Imagery used for defense intelligence purposes is generally collected via satellite imagery or aerial photography .
A satellite or artificial satellite[ a] is an object, typically a spacecraft, placed into orbit around a celestial body. Satellites have a variety of uses, including communication relay, weather forecasting, navigation ( GPS ), broadcasting, scientific research, and Earth observation. Additional military uses are reconnaissance, early warning ...
A traditional false-color satellite image of Las Vegas. Grass-covered land (e.g. a golf course) appears in red. In contrast to a true-color image, a false-color image sacrifices natural color rendition in order to ease the detection of features that are not readily discernible otherwise – for example the use of near infrared for the detection of vegetation in satellite images.

Remote sensing of mangrove and vegetation as a natural barrier to manage risks therefore becomes a hot topic. The recent advancement and development is highly anticipated in the near future, especially as hyperspectral imaging system and very high resolution (up to sub meter grade) satellite images prevails.
