CLARIS - Coastal LIDAR and Radar Imaging System - LiDAR News

Meanwhile, the LIDAR instrument produces highly accurate maps of beach topography, above the water and beneath it.

Researchers from the US Army Corps of Engineers who study the beaches of the Outer Banks in North Carolina have long noticed that storms cause particularly severe erosion in areas they call hot spots. “There was no way to go out during a storm and measure what the sandbars were doing, what the waves were doing, where the water was rushing up into the dunes,” Dr. McNinch a coastal scientist explained.

The solution – CLARIS, essentially a Sno-Cat fitted with radar and lidar sensors, that travels along the beach as its radar makes precise measurements of the speed, frequency and size of waves. Meanwhile, the LIDAR instrument produces highly accurate maps of beach topography, above the water and beneath it.

UK: Space age agronomy on show at the World Potato Congress

UK: Space age agronomy on show at the World Potato Congress | Remote Sensing News | Scoop.it

Satellite technology developed during the Cold War is set to deliver state-of-the-art crop monitoring systems to help growers improve agronomy and drive up profits. Although the technology dates back several decades, its capabilities for remote sensing of crops are only now being realised thanks to relatively recent developments in information technology, says Stephanie Race, chief executive of San Francisco-based Earth Analytics Group, who will be speaking at the World Potato Congress.

“Satellite remote sensing can inform observations of crop canopy development at scale. When used with meteorology, soils data and crop models, growers can monitor in-season production and reduce water use to achieve more favourable yields at a lower cost,” she explains. “Growers can evaluate many more fields with remotely-sensed data than they could by walking them – we are saving time with technology.”

China entra na era dos satélites de alta resolução | MundoGEO | Remote Sensing News | Scoop.it

Lançado em 22 de dezembro de 2011, o primeiro satélite de alta resolução da China passa agora por testes em órbita. As informações são do Centro de Dados de Satélites do país, que afirmou também que o satélite ZY-1-02C já enviou imagens de vários locais.
Este é o primeiro satélite personalizado para estudos de recursos terrestres, que irá servir à clientes Chineses. Com duas câmeras coloridas de alta resolução e uma câmera multi-espectral, o satélite irá fornecer aos clientes imagens para auxiliar serviços de resgate em desastres, desenvolvimento da agricultura, monitoramento ambiental e outras aplicações.

Satellite Image in 3D View of “Mountains of Ararat” in Turkey

Satellite Image in 3D View of “Mountains of Ararat” in Turkey | Remote Sensing News | Scoop.it

ASTER (15m) Satellite Image of Mountains of Ararat, Turkey in 3D View

Mount Ararat (16,940 feet, 5165 m) the largest volcano in Turkey. Ararat consists of two volcanic peaks: Big Ararat (5137 m) and Little Ararat (3,914m). The top of Big Ararat is covered with snow all year long. The Old Testament story of Noah says that Noah’ ark came to rest on Ararat following the Great Flood. This image is a 3-D perspective view looking from the southwest, created by draping a simulated natural color image over an ASTER-derived digital topography model. Although not currently active, its most recent eruption has probably been within the last 10,000 years. It is located in extreme northeastern Turkey, near the borders with Iran and Armenia. A number of claims by different explorers said to have found remnants of Noah’s Ark on Mt. Ararat have led to continuing expeditions to the mountain, many of which have focused their searches on the gorge area. More information on Mt. Ararat, visit here.

dominoc925: Simple canopy height derivation using Global Mapper

dominoc925: Simple canopy height derivation using Global Mapper | Remote Sensing News | Scoop.it

he forest canopy height is the height of the highest vegetation above the ground level. It is possible to calculate the canopy height from LiDAR derived digital terrain models (DTM) and digital surface models (DSM) gridded datasets by doing a simple subtraction in Global Mapper. The example below shows how to use the Combine Terrain Layers function in Global Mapper to calculate the canopy height.

Colour infrared aerial imagery | From High Above | Remote Sensing News | Scoop.it
All medium and large-format digital aerial camera systems can acquire information in the visible part of the electromagnetic to produce natural colour images using their Red, Green and Blue channels. These camera systems are also able to acquire data from an invisible part of the electromagnetic spectrum called near-infrared (NIR).

The light emitted from the sun and reflected by vegetation possesses a very distinctive response in the near-infrared wavelength which can be used in combination with visible wavelengths. Particularly useful to extract qualitative and quantitative information about the health of plants, NIR can also be used to extract water quality information...

"I don’t often post such things but this time-lapse video taken from the ISS as it orbits the globe at night is astonishing. What a stunning view – the cities illuminated the auroras as a glowing shell flaring at the poles- the bright flashes of electrical storms. Best 3 mins you’ll spend to day"

Institute for Science and International Security › ISIS Reports › Korean Peninsula › Light Water Reactor Construction Progressing at Yongbyon Nuclear Site

Institute for Science and International Security › ISIS Reports › Korean Peninsula › Light Water Reactor Construction Progressing at Yongbyon Nuclear Site | Remote Sensing News | Scoop.it

ISIS has acquired a new satellite image taken on February 3, 2012 of the Yongbyon nuclear site in North Korea which shows that construction of the light water reactor is progressing. In the new image, the reactor’s turbine building appears externally complete (see figure 1). The dome for the reactor building, however, remains on the ground next to the building. An earlier satellite image from September 20, 2011 shows the turbine building still under construction (see figure 2). Figure 3 shows the fuel fabrication facility at the Yongbyon nuclear site which includes the gas centrifuge uranium enrichment plant. Figure 4 shows the reprocessing facility at the Yongbyon nuclear site.

GeoEye › Gallery Featured Satellite Images › Harrisburg Tornado Damage Harrisburg, IL | Remote Sensing News | Scoop.it
GeoEye: The premier provider of satellite and aerial imagery and geospatial information.

This one-meter resolution satellite image of Harrisburg, Illinois, was collected March 1, 2012, just one day after a Level 4 tornado touched down on February 29, 2012. The image clearly shows the tornado’s path from west to east, and the major damage to buildings, structures and other facilities, including the Harrisburg Medical Center, one of the largest health care facilities in southeastern Illinois. The image was collected by GeoEye’s IKONOS satellite while flying 423 miles above the Earth at an average speed of 17,000 mph. The imagery could be used to provide insight on relief efforts and emergency response and aid in rebuilding efforts.
