The Land Cover Map 2015 (LCM2015) is a map of land cover classes across the UK produced every 5-10 years. It is based on classification of Landsat satellite imagery from the summer and winter and additional data layers. The LCM2015 contains over 7.5 million land parcels classified into 21 land cover classes. It is an important resource used widely in research, commercial, government and nonprofit applications related to agriculture, ecology, climate, planning and more.

What is LiDAR_ A Guide to its Technical Aspects.pdf

Anil

LiDAR, which stands for Light Detection and Ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects in its field of view. LiDAR systems are widely used in various applications, including topographic mapping, forestry, autonomous vehicles, archaeology, and urban planning. Here's a guide to the technical aspects of LiDAR

Lidar : light detection and rangeing

Rahul Bhagore

Rahul Bhagore presented on LIDAR (Light Detection and Ranging) technology. LIDAR uses laser pulses to measure distance by illuminating a target and analyzing the reflected light. It has applications in fields like agriculture, conservation, and law enforcement. LIDAR systems can be airborne, terrestrial, mobile, or static. Key components include lasers, scanners, detectors, and navigation systems. LIDAR provides highly accurate 3D data at large scales and through foliage, with advantages over other remote sensing methods.

Tejistha Pradhan

LiDAR is an active remote sensing technique that uses laser light to image objects. It was invented in the 1960s and became popular after being used on the Apollo 15 mission to map the moon's surface. LiDAR works by measuring the time it takes for a laser pulse to be reflected off an object and return, allowing it to create precise 3D models of surfaces and objects. It has numerous applications like terrain mapping, forestry, archaeology and more due to its speed, accuracy and ability to capture dense point cloud data without human involvement. While powerful lasers pose safety risks, LiDAR provides significant advantages over passive imaging and is an important remote sensing tool.

LiDAR uses laser light to rapidly create high-resolution 3D models of objects and terrain. It has largely replaced photogrammetry for topographic mapping due to its ability to collect data day or night and its direct measurement of ground surfaces. While public LiDAR datasets are useful for planning, private firms can benefit more from terrestrial and aerial LiDAR for detailed civil engineering and surveying projects. LiDAR allows rapid mapping of complex sites and piping networks to support master planning, grading, utilities, and other design work.

Introduction to lidar and its application

Vedant Srivastava

LiDAR acronym as Light Detection and Ranging is remote sensing technology having several technical and socialite advantages. This technology is basically used to make high resolution digital map to provide the real time data. This data can be processed and used to extract the useful information. A typical LIDAR system consists of three main components, a GPS system to provide position information, an INS unit for attitude determination, and a LASER system to provide range (distance) information between the LASER firing point and the ground point. In addition to range data, modern LIDAR systems can capture intensity images over the mapped area. Therefore, LIDAR is being more extensively used in mapping and GIS applications.

Lidar

aksh rana

Lidar is an optical remote sensing technology that uses light (often from a pulsed laser) to measure distance. It works by illuminating a target with a laser and analyzing the reflected light. Common components of a lidar system include a laser, scanner/optics, photodetector, and receiver electronics. Lidar has advantages over radar like faster lock-on time and narrower beam spread. Applications include agriculture, mapping, oil/gas exploration, engineering, autonomous vehicles, and atmospheric sensing from aircraft or satellites. Recent advances include lidar speed guns, Google's driverless car which uses lidar for navigation, and autonomous cruise control systems using lidar.

Mobile devices broadcast information passively through protocols like mDNS and NetBios that can be used to profile and fingerprint individuals. This metadata includes a person's name, device details, social media profiles, locations visited and more. While concerning for privacy, there are some mitigation tips like disabling WiFi when not in use. In the future, passive profiling may become more advanced through integration with other tools and online databases to create detailed profiles of individuals based solely on information broadcast from their mobile devices.
