Remote sensing image analysis has evolved significantly with the advent of deep learning, offering advanced techniques to process and interpret complex geospatial data. Traditional remote sensing image analysis methods relied heavily on manual feature extraction and statistical approaches. However, these methods often struggled with high-dimensional data and diverse environmental conditions. The integration of deep learning […]
Synthetic Aperture Radar (SAR) is an advanced remote sensing technology that uses radar waves to generate high-resolution images of the Earth’s surface. Unlike optical sensors, SAR operates in the microwave spectrum, allowing it to penetrate clouds, fog, and even some vegetation, making it highly effective for all-weather and day-and-night observations (Henderson & Lewis, 1998). SAR […]
Light Detection and Ranging (LiDAR) is a powerful remote sensing technology that uses laser pulses to measure distances and generate high-resolution 3D representations of terrain and vegetation. LiDAR has become an essential tool in topographic mapping, forestry analysis, and environmental monitoring due to its ability to penetrate vegetation canopies and produce detailed surface and elevation […]
Hyperspectral imaging is an advanced remote sensing technology that captures a wide range of spectral bands across the electromagnetic spectrum. Unlike traditional multispectral imaging, which collects data in a limited number of bands, hyperspectral imaging provides continuous spectral information, allowing for detailed material identification and classification (Goetz, 2009). This technology is widely applied in agriculture, […]
Remote sensing platforms have evolved significantly, offering diverse options for collecting geospatial data across different scales and applications. Among the most commonly used platforms are satellites, drones, and airborne sensors, each with unique advantages and limitations (Jensen, 2007). These technologies support critical applications in environmental monitoring, agriculture, disaster management, and urban planning (Lillesand et al., […]
The electromagnetic spectrum is a fundamental concept in remote sensing, defining the different wavelengths of energy used to observe and analyze the Earth’s surface. Various remote sensing technologies utilize different portions of this spectrum, from visible light to microwave radiation, to capture and interpret geospatial data (Jensen, 2007). Understanding how different wavelengths interact with Earth’s […]
Remote sensing is a fundamental technique in geospatial science that enables the observation and analysis of the Earth’s surface without direct contact. It is widely used in environmental monitoring, agriculture, disaster management, and urban planning (Jensen, 2007). One of the most important distinctions in remote sensing is between passive and active sensors. These two categories […]
Remote sensing has revolutionized the way we observe and analyze the Earth’s surface, enabling scientists, engineers, and decision-makers to access critical geospatial data. Among the most widely used remote sensing methods are satellite-based and aerial-based sensing, each offering distinct advantages and limitations (Tucker & Sellers, 1986). These methods play a significant role in monitoring environmental […]
Remote sensing is a powerful technology that enables the acquisition of information about objects or areas from a distance, typically using satellites, drones, or aircraft-mounted sensors. This method has become an essential tool in various fields, including environmental monitoring, agriculture, disaster management, and urban planning (Lillesand et al., 2015). By capturing and analyzing electromagnetic radiation […]
