Google Earth is a web and computer program that renders a 3D representation of Earth based primarily on satellite imagery.The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles.
GeoEye's GeoEye-1 satellite was launched on September 6, 2008. [9] The GeoEye-1 satellite has high resolution imaging system and is able to collect images with a ground resolution of 0.41 meters (16 inches) in panchromatic or black and white mode. It collects multispectral or color imagery at 1.65-meter resolution or about 64 inches.
The first was a commandable coronagraphic mask that included two occulting spots, one of diameter 1.8" at the center of the field and the other of diameter 3.0" nearer to a corner. The first spot was the most popular of the two, for example, for imaging circumstellar disks around nearby bright stars or the host galaxies of luminous quasars.
There were two precursors to the introduction of SA-mount cameras, the manual-focus Sigma Mark-I in 1976, which still featured a M42 screw lens mount, and the SA-1 of 1983 with Pentax K-mount. Mechanically, the (inner) SA-mount is similar to the Pentax K-mount as well, [ 2 ] but with a flange focal distance of 44.00 mm, identical to that of the ...
Coolpix compact digital cameras, Nikon 1 series MILCs, and D-series DSLRs: OM System: Japan: C-, D-, FE-series, Tough and Stylus compact digital cameras; E-series DSLRs based on the Four Thirds System; and two series of mirrorless interchangeable-lens cameras based on the Micro Four Thirds System, the PEN digital series and OM-D series(Former ...
The United Nations also used DubaiSat-1 images to monitor relief efforts following the 2011 Tōhoku earthquake and tsunami in Japan. [11] [12] The satellite accommodates two main payloads. The primary payload is the Dubai Medium Aperture Camera (DMAC), and the secondary and experimental payload, the Space Radiation Monitor (SRM). [3]
Example video in 16K (16000 × 9000 pixels) A VR video in 16K (16000 × 8000 pixels) 16K resolution is a display resolution with approximately 16,000 pixels horizontally. The most commonly discussed 16K resolution is 15360 × 8640, which doubles the pixel count of 8K UHD in each dimension, for a total of four times as many pixels. [1]
One algorithm (used in GMR-1 phones) is a variant of the A5/2 algorithm used in GSM (used in common mobile phones), and both are vulnerable to cipher-text only attacks. The GMR-2 standard introduced a new encryption algorithm which the same research team also cryptanalysed successfully. Thus satellite phones need additional encrypting if used ...
