Light Detection And Ranging ( Lidar )

Trp. Burrell was participating in a Lidar project on I-85 north near Popular Creek Road in Vance County. Trp. Burrell was notified of a black SUV traveling north at a high rate of speed. Trp. Burrell activated his blue lights and siren and attempted to make an enforcement stop, but was impeded by a silver Mitsubishi SUV in the passing lane. Trp. Burrell followed behind this vehicle a short distance with his blue lights and siren activated, and the vehicle yielded to the left toward the median. Trp. Burrell proceeded north on I-85 and stopped the black SUV that originally was the target of the Lidar project. This complaint is unfounded based on Trp. Burrell was not traveling at a high rate, and the vehicle in front of him yielded to the

With the increase in computer processing power, this LiDAR data should be should be consider in developing the overland flow path understanding in City Basement Flooding Program. Access to this additional data source will increase the accuracy of model development and validation.

Light Detection and Ranging (LiDAR) is considered an old technology, but also a new technology at the same time. LiDAR has existed for close to 20 years. However the system has only been available in industry for the past 10 years. This is due to the costs associated with having a functioning system. There is many applications used by this technology. Some examples of this are survey data, structural information, speed traps, and mainly survey and topographic data. LiDAR has been around since the early 1950’s. Once the development of accurate positioning systems took place LiDAR became a viable option for mapping technology. This system measures distance by targeting an area with a laser and analyzing the reflected light. This is precision mounted on the underside of an aircraft, the sensor emits rapid pulses of ultraviolet or infrared light which in turn measures said distances. In turn this system can target a wide range of materials. From terrain to clouds and gasses. (Ranges are determined by computing the amount of time it takes the light to leave the airplane, travel to the ground and return to the sensor. A sensing unit’s precise position and attitude, instantaneous mirror angle and the collected ranges are used to calculate 3-D positions of terrain points. As many as 100,000 positions or “mass points” can be captured every second.)

Dronetech is a new company in the drone navigation industry and since it was founded, it has been able to develop a standard operating procedure that has been largely responsible for the identification, acquisition, and transfer of knowledge between the different sections of the company’s network. Because of the skill displayed by its management when handling diverse issues the company has been able to develop a clientele which in such diverse institutions in such a short time, where other companies take years to achieve the same. The vision of Dronetech is to generate an

This technology is called Drone Technology. This drone is an unmanned vehicle which was designed to provide support the real time analysis of the flexibility of the network. These drones are designed to monitor the condition of bridges and electrical systems which helps in capturing infra-red pictures as well as the HD images to classify the linkages. Usage of drones has been growing rapidly which allows to improve work culture. They moreover reduce the requirement for the employees who are exposed to altitudes and electrification hazards that accompany the asset assessment (Aurizon Beyond 2020: Sustainability Report

“The Association for Unmanned Vehicle Systems International is a trade group for drone manufacturers and users. It says agriculture could account for 80 percent of all commercial drone use” “With advancements in technology, 3-D images and temperature readings from drones could be tied with other data. The information could give farmers even more information about growing conditions.”

In my opinion the LIDAR (light detection and ranging) and the GPR (ground penetrating radar) from the article "search for ancient civilizations" are the best inventions compared to the rest because they (together) use a chunk of land and research it with out digging it up which would take forever so they study the chunk of land by using satellite imagery and the GPR again to study the chunk to see if there is any buried treasure making great use of time and less injured people too!, Although I tip my hat for the dropsonde hurricane sensor and the planes (WC-130J)from the article "weather reconnaissance" but i find it "low tech" and "most likely replacable in the near future" because mankind is always coming up with new things everyday (although

In the short story “A Clean, Well-Lighted Place” Ernest Hemingway writes about a deaf man who sits alone and drowns his sorrows in brandy at a local café. Two waiters work their regular shifts and view the usual client very differently. Throughout the short story, Hemingway uses symbols to hint at “nada” or nothingness. This symbolic concept of nothingness is developed through the setting, characters and writing style.

Using remote sensing to monitor United Nations World Historic Sites is key in regions where physical monitoring is not practical, the site is too fragile to endure repeated monitoring events, or extremely dangerous to people. Some sites are located in regions that are remote, in conflict areas, densely covered by tree canopies, or too large to practically cover by other means. Methods being developed or used today are using RADAR to monitor geoglyphs in Peru, LIDAR to map medieval wall city gates in Spain, satellite imagery identifying sites in war-torn Syria, and very-high-resolution aerial imagery to map the canopy tree species in Cambodia. These methods will allow organizations to better monitor the sites without causing undo stress

Imaging radar is used to create a two-dimensional image typically of landscapes. An imaging radar create a picture of the observed object or area. Imaging radars have been used for mapping of the earth and other celestial objects and to categorize targets for military systems.

These maps are available through US Geological Survey, but in case of a precise assessment, a licensed surveyor in accordance with specifications tailored to the construction could be required. The topography influences aspects of the site, such as the microclimate, distribution of plant and animal species, water movement, and storm water management practices. The goal of this section of the LEED rating system is to promote options for minimizing disturbance and skillfully incorporating the existing topography into the design.

As LED technology increases everyday it presents an opportunity to significantly reduce energy consumption, but also change the way users deploy, monitor and control these lighting systems. Today there are various solutions allowing cities to control light fixtures through a cloud based systems connecting to a computer, a tablet or other devices. These solutions smarten up a road’s or park’s lighting system by enabling independent handling of each fixture. Integrating a cloud based system will also lower maintenance cost as it provides a real-time control and monitoring of individual fixtures allowing instant notifications of malfunction and pin points the exact location of the fixture needing maintenance.

The height of the lower laser is deliberately chosen such that fallen weights are not identified, as the current collection method is not designed to acquire them. Case 1 of Figure 10 displays a successfully identified weight, one hotspot is identified by the IR camera corresponding to the lower laser, as directly above no other hotspot is detected, it is determined a package viable for collection has been detected. Case 2 and 3 display occurrences that are entirely ignored by the camera configuration, as no hotspots are present. Case 4 can be deemed as a non-package object, due to the presence of two hotspots stacked vertically.

Prior to atmospheric correction and radiometric calibration, both sentinel and Landsat 8 images were geo referenced to UTM 37N coordinate system (WGS 84 datum and Spheroid) and subset image was created. Landsat 8 image acquired in the form of digital number (DN) were converted to radiance and TOA reflectance values using ENVI 5.3 software. Atmospheric correction was also employed using dark object subtraction module of ENVI 5.3 (ExelisVisual Information Solutions, 2010). The DN of Sentinel-2A LIC productwere divided by 10000 to obtain TOA reflectance. The false color composite of Sentinel 2 and Landsat 8 image of the study site after preprocessing is shown in fig 3.

Remote sensing is a key technology for quantifying landscape pattern and processes, without being in physical contact of that landscape using electromagnetic radiation either from an aircraft or satellite (active) or passive from sunlight (Newton et al., 2009; Tuner, 2005; Frohn, 1998). When more African countries acquire the ability of launching their own satellites they will be able to customize maps to the unique needs of the countries phenomena like wetlands, land use, deforestation and climate change over time. In so doing, scientists in these countries will be able to advise policy makers more accurately in better land use and how to combat the adverse effects of climate change. Moreover, Geospatial Information System usage allows the data obtained from the satellite maps to be analyzed and easily interpreted using computer software. For instance, data from remote sensing is used to predict habitat types for Wetlands biodiversity assessment and necessary action plans can be put in place to mitigate any adverse effects that have occurred over time (see figure 3 below).
