Remote Sensing Environmental Applications and Uses

At first glance, it might seem that technology and the environment are at opposite ends of the spectrum. However, people find different ways to protect the environment by applying technologies. Innovation enables us to build a more sustainable future, produce green and renewable energy, monitor endangered species, use natural resources more efficiently, and more. All this would be impossible without technologies, among which remote sensing takes a key position.

Remote sensing is scanning the Earth to obtain data using satellites or high-flying aircraft. Satellite data can be used for many purposes in various fields of human activity, including natural resource mapping, modeling of ecological processes, hydrological modeling, assessment of vegetation cover, and other studies. In combination with other technologies, remote sensing enables obtaining valuable data and analyzing it. You can find out more about sensing applications and their use with other technologies here.

Remote Sensing Advantages

One of the main advantages of using remote sensing data for monitoring the environment today is the availability of data and images with various characteristics, including various spatial, spectral, and temporal resolutions. Sensors with different features also contribute significantly to expanding the capabilities of environmental monitoring applications. Remote sensing technologies also provide several other valuable advantages and abilities, including

  • data collection over large areas
  • identification of physical objects and natural features on the surface of the Earth
  • systematic observation and tracking of changes
  • exploration of hard-to-reach places

In addition, RS data can be integrated with other information. It makes it possible to obtain a reliable basis for making effective decisions to save the environment.

5 examples of RS application

Remote sensing has many applications in different sectors, including ocean and coastal applications, natural resource management, hazard assessments, etc. In addition, various analyzes are carried out through remote sensing technologies to facilitate effective planning and management.

Agriculture

Remote sensing is widely used in agriculture and offers farmers valuable observation and analysis opportunities. Experts can predict the amount of harvest that will be produced on a particular farm over a certain period analyzing satellite data. Also, with the help of this technology, farmers can assess crop damage and analyze various crop planting systems.

Remote sensing also plays a critical role in detecting stress, drought, and land degradation, identifying pests and diseases, as well as a mechanism to combat them. The discussed technology is crucial for assessing soil moisture and managing irrigation. Farmers have an opportunity to identify nutrient deficiencies in the soil using this technology.

Mining

Remote sensing images are also widely used in the mining industry. They are used at all stages of work. With the help of satellite images, specialists search for and explore mineral deposits. Also, this technology is used during the extraction of resources, the closure and reclamation of mines. Compared to ground-based imagery, images from space satellites and onboard UAV platforms provide more information. Images obtained from space allow you to cover large areas. Computer processing technologies allow analyzing the processes in these areas but are not visible to the naked eye.

Forestry

With the help of remote sensing technology, the coverage, moisture, and chemical soil composition and vegetation structure are measured. Monitoring biodiversity would also not have been possible without remote sensing. These data make a significant contribution to understanding the functions and processes of forest ecosystems. In addition, they enable specialists to classify forests by ecosystem, biome, and community.

The applications of RS in forestry are a crucial example of how technology can help save the planet. The data allows identifying potential fires and other risks. Furthermore, RS technologies play a vital role in the policies of reducing deforestation, greenhouse gas emissions, and forest degradation.

Oceanography

Satellite technologies have a wide range of applications in oceanology, the most crucial of which is assessing the sea surface. Satellite data also makes it possible to determine temperature, wave characteristics, chlorophyll content, the concentration of yellow matter and suspended sediment, potential fishing zone, etc. RS is also beneficial for coastal resources and aquatic biodiversity. monitoring

Hydrology

With the development of RS and GIS tools for processing, managing, storing, and retrieving various types of data and efficient computing systems, RS has become more widespread in hydrology. The use of this technology makes significant contributions to water research and management, including mapping of watersheds, assessing changes, and measuring various hydrological variables.

Conclusion

Remote sensing provides ample opportunities for observing and analyzing processes in the environment. It is one of the greenest technologies used in various industries to help you use resources more efficiently. Remote sensing continues to evolve and brings even more benefits in combination with other innovative technologies.
