Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation, especially the Earth. Remote sensing is the evaluation of information on an object or phenomenon without any physical contact with the particular object and therefore unlike in situ observation. Remote sensing generally refers to the use of aerial sensor technologies to detect and classify objects on Earth using propagated signals. There are two types of remote sensing: active and passive. Active remote sensing means when a signal is first transmitted from an airplane or satellites and passive means when information is recorded. The scientific journal is a periodical publication intended to advance science, generally by reporting new research. There are thousands of scientific journals being published, and many more have been published at different times in the past. Most journals are highly specialized, although some of the older journals publish articles and scientific articles in a wide range of scientific fields. Scientific journals contain peer-reviewed articles to ensure that the articles meet the quality and scientific validity standards of the journal. The publication of research results is an essential part of the scientific method. If they describe experiments or calculations, they must provide enough detail for an independent researcher to repeat the experiment or calculation to verify the results. Each of these review articles is part of the permanent scientific dossier.
