Applications of satellite imagery and remote sensing data are put into practice to support management and monitoring activities in all areas such as security – national defense, environmental resources, agriculture – forestry, management of the forest…
How is remote sensing image approached?
Satellite image data and remote sensing image data provide important information in many surveillance applications such as image capture, transformation detection, and overlay classification. Remote sensing techniques are one of the important techniques used to collect information related to Earth’s environmental resources.
Types of Application of satellite images and remote sensing data
Popular satellite image data is easily accessible and accessible through popular map applications such as Google Earth, Bing Maps, etc. Users can easily find the location where they live, from applications Their great work has helped the GIS community to develop plans to monitor natural disasters and climate change and to provide defensive guidance.
Photos from remote sensing image acquisition stations allow satellite images and remote sensing data to include spectral solutions, space and time. Data relate to components of remote sensing images, the main aspects affecting the accuracy of objects under the ground are spatial resolution. Time resolution will assist in managing the construction of land cover maps, which will help detect land-use changes and transport planning.
Classification of satellite image applications and remote sensing data
From Lansat and SPOT images, countries have used remote sensing data to serve the purpose of monitoring each other through scientific experiments, and it has quickly become a powerful growth industry. Application in all areas of life.
To better understand the applications of satellite imagery and remote sensing data below, let us learn about their five common applications:
Remote sensing image data provides background maps
By using high-resolution satellite images and wide coverage, frames and scenes on the map will be detailed.
Processing and analyzing remote sensing spectral images to search for mineral deposits
In order to achieve high yields in the process of mineral exploration and mining, it is important to first know about the mineral potential of that area. By using remote sensing images in the detection of mineral deposits, remote sensing experts use and analyze the spectral bands of satellite images, thereby building up mineral maps through solid indicators. specialization of the spectrum band obtained.
Remote sensing photo application disaster recovery planning
The consequences of natural or man-made disasters are sometimes difficult to assess the extent of the devastation and its consequences. Assessing the level of disaster impact is essential to provide timely solutions. This job requires accuracy and speedy. By using remote sensing images based on landmarks before and after a disaster to assess the situation and the extent of the disaster, to provide timely rescue and remedial measures.
Application of remote sensing images in agricultural development
With the rapid increase in the global population, the demand for agricultural output has also increased, leading to an increase in the issue of agricultural resource management. To meet these requirements, we need to have reliable data on the quantity, quality, and location of each of these resources. The use of satellite images and GIS systems is an excellent choice in identifying, classifying, determining the location, output, and quality of agricultural products.
3D GIS model
3D city model is a digital model of urban areas that represent the surface, terrain, buildings, vegetation, infrastructure and landscape elements as well as objects related to urban areas. Their components are described and represented by corresponding two-dimensional and three-dimensional spatial data and geographic reference data.
The 3D city model supports the presentation, exploration, analysis, and management of tasks in a large number of different application domains. 3D GIS is an effective solution for larger locations and remote places where manual surveys are used. Many urban/rural planning departments require GIS data such as 3D, drainage, …
