Is remote sensing limited to images collected by satellites?

No, remote sensing is not limited to images collected by satellites. It encompasses a variety of methods and technologies, including aerial photography from drones and aircraft, ground-based sensors, and even data collected through terrestrial and marine systems. These diverse platforms allow for the collection of various types of data, such as multispectral and hyperspectral imagery, LiDAR, and radar, enhancing the understanding of the Earth's surface and environment.


What is the role of remote sensing in mineral exploration?

Remote sensing plays a crucial role in mineral exploration by providing valuable data on the Earth's surface without physical contact. It helps in identifying potential areas for mineral exploration by detecting geological features, alterations, and anomalies that indicate the presence of minerals. Remote sensing techniques like satellite imagery and hyperspectral imaging aid in reducing exploration costs and time by narrowing down areas for further detailed exploration.


How can you recognize gold by remote sensing?

Gold can be recognized by remote sensing through the analysis of geological features associated with gold mineralization, such as alteration patterns, mineral associations, and structural controls. Remote sensing techniques like hyperspectral imaging can detect unique spectral signatures of minerals associated with gold deposits, aiding in the identification of potential gold-rich areas. Additionally, satellite imagery can be used to map out geological structures and anomalies that may indicate the presence of gold mineralization.


What is band ratio in remote sensing?

Band ratio in remote sensing is a technique that involves dividing the pixel values of one band of an image by the pixel values of another band. This can enhance certain features or properties in the image, such as vegetation health or mineral composition, by highlighting the differences in spectral responses between the two bands. It is a common method used for image interpretation and analysis in various remote sensing applications.


What is multi channel images in image processing?

Multi-channel images in image processing refer to images that contain multiple layers of data, each representing different information about the image. Common examples include RGB images, which have three channels corresponding to red, green, and blue, and multispectral or hyperspectral images, which can have many more channels capturing various wavelengths of light. Each channel can provide unique insights, enabling more advanced analysis and processing techniques, such as improved object recognition and image classification.
