The oceans take up over 70 percent of the planet's surface, and they have a significant role to play in climate regulation, marine ecosystems, transportation, fisheries, and coastal economies. The monitoring of such a large dynamic environment cannot rely on ground surveying alone. Using satellite imagery to monitor oceans is a solution for efficiently observing the state of oceans. State-of-the-art Earth observation satellites use optical, multispectral, hyperspectral, and SAR imagery, which...

There are two technologies that are used for the collection, management, analysis, and understanding of geographical data: Geographic Information System (GIS) and Global Positioning System (GPS). Even though GIS and GPS are employed in conjunction, their functions are not similar. While GPS works primarily to determine the location of a receiver, GIS is used for the purposes of storing, analyzing, visualizing, and managing spatial data. It is important for specialists in surveying, mapping,...

Remote sensing is a key technology that allows the gathering of information from the Earth's surface without being in physical contact with the studied areas or objects. This technology is an integral part of Geographic Information Systems (GIS), environmental monitoring, agriculture, forestry, urban planning, disaster management, military operations, and observations related to the planet. Any remote sensing device consists of a remote sensing sensor. The sensor's purpose is to catch and...
