Remote sensing is the assessment of information about an object or phenomenon without any physical contact with the particular object and thus in contrast to in situ observation. Remote sensing generally refers to the use of aerial sensor technologies to detect and classify objects on Earth by means of propagated signals. Remote sensing is of two types they are active and passive. Active remote sensing means when a signal is first emitted from aircraft or satellites and passive means when information is recorded.
Journal Article is sometimes called a Scientific Article, a Peer-Reviewed Article, or a Scholarly Research Article. Together, journal articles in a particular field are often referred to as The Literature.
Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method.
Because articles in scientific journals are specific, meticulously cited and peer-reviewed, journal databases are the best place to look for information on previous research on your species. Without a background in the field, journal articles may be hard to understand - however, you do not need to understand an entire article to be able to get valuable information from it.
