Geotagged Photograph
A geotagged photograph is a photograph which is associated with a geographic position by geotagging. Usually this is done by assigning at least a latitude and longitude to the image, and optionally elevation, compass bearing and other fields may also be included. In theory, every part of a picture can be tied to a geographic location, but in the most typical application, only the position of the photographer is associated with the entire digital image. This has implications for search and retrieval. For example, photos of a mountain summit can be taken from different positions miles apart. To find all images of a particular summit in an image database, all photos taken within a reasonable distance must be considered. The point position of the photographer can in some cases include the bearing, the direction the camera was pointing, as well as the elevation and the dilution of precision (DOP). Methods There are a few methods of geotagging photographs, either automatic or manual. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canon PowerShot S100
The Canon PowerShot S100 is a high-end 12.1-megapixel compact digital camera announced and released in 2011. It was designed as the successor to the Canon PowerShot S95 in the S series of the Canon PowerShot line of cameras. The S100 is a similar camera to S90 and S95 with several significant improvements. It has improved noise reduction, white balance and shadow correction. This camera is the first camera in the S series line to use the CMOS Sensor which gives the camera a higher performance and better light sensitivity. The S100 is also the first camera in the series to feature 1080p video recording in 24 frames per second. Canon has acknowledged that some PowerShot S100 digital cameras encounter a lens error caused by a disconnected part inside the camera. This makes the camera unusable. Canon offered free repairs well beyond the warranty date, even if the camera has a serial number outside the range mentioned in the product advisory; however, this ended when they stopped ...

Nikon D1
The Nikon D1 is a digital single-lens reflex camera (DSLR) made by Nikon Corporation introduced on June 15, 1999. It featured a 2.7-megapixel image sensor, 4.5-frames-per-second continuous shooting, and accepted the full range of Nikon F-mount lenses. The camera body strongly resembled the F5 and had the same general layout of controls, allowing users of Nikon film SLR cameras to quickly become proficient in using the camera. Autofocus speed on the D1 series bodies is extremely fast, even with "screw-driven" AF lenses. Although Nikon and other manufacturers had produced digital SLR cameras for several years prior, the D1 was the first professional digital SLR that displaced Kodak's then-undisputed reign over the professional market. Unusual for a DSLR, the D1 uses the NTSC color space instead of the conventional sRGB or Adobe RGB color spaces. The resulting color on the D1 can be a bit unorthodox, but methods of correcting and/or compensating for the color problem are readily a ...

Assisted GPS
Assisted GNSS (A-GNSS) is a GNSS augmentation system that often significantly improves the startup performance—i.e., time-to-first-fix (TTFF)—of a global navigation satellite system (GNSS). A-GNSS works by providing the necessary data to the device via a radio network instead of the slow satellite link, essentially "warming up" the receiver for a fix. When applied to GPS, it is known as assisted GPS or augmented GPS (abbreviated generally as A-GPS and less commonly as aGPS). Other local names include A-GANSS for Galileo and A-Beidou for BeiDou. A-GPS is extensively used with GPS-capable cellular phones, as its development was accelerated by the U.S. FCC's 911 requirement to make cell phone location data available to emergency call dispatchers. Background Every GPS device requires orbital data about the satellites to calculate its position. The data rate of the satellite signal is only 50 bit/s, so downloading orbital information like ephemerides and the almanac directl ...

DSLR
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the viewfinder, or the image sensor when the shutter release button is pressed. The viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera's sensor as it presents it as a direct optical view through the main camera lens, rather than showing an image through a separate secondary lens. DSLRs largely replaced film-based SLRs during the 2000s. Major camera manufacturers began to transition their product lines away from DSLR cameras to mirrorless interchangeable-lens cameras (MILC) beginning in the 2010s ...

Sony Alpha 55
The Sony α55 (model variants SLT-A55V with GPS, SLT-A55 without GPS depending on country) is a midrange-level SLT camera, released in August 2010. Its design is novel due to its being the first digital single-lens translucent camera (SLT), along with the Sony α33. As an SLT it employs a semi-transparent mirror instead of an opaque mirror, which enables phase detection autofocus in live view. The design also replaces the optical viewfinder present in conventional DSLR with a high-resolution electronic viewfinder. The translucent mirror is fixed in position so does not have to flip up to take a still image, enabling rapid continuous shots of up to 10 frames per second. The static mirror also eliminates "mirror slap", the noise produced by the movement of the mirror during a shutter actuation, making the A55 quieter than standard DSLRs. The A55 is one of the first four Sony Alpha DSLR / SLT cameras with video mode included, capable of 1080i 1080i (also known as Full HD or ...
