ASTER Global Digital Elevation Map ASTER Global Digital Elevation Map ASTER Global Digital Elevation Map Announcement The Ministry of Economy, Trade, and Industry (METI) of Japan and the United States National Aeronautics and Space Administration (NASA) jointly announced the release of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model Version 2 (GDEM V2) on October 17, 2011. The first version of the ASTER GDEM, released in June 2009, was generated using stereo-pair images collected by the ASTER instrument onboard Terra.
ASTER GDEM coverage spans from 83 degrees north latitude to 83 degrees south, encompassing 99 percent of Earth's landmass. The improved GDEM V2 adds 260,000 additional stereo-pairs, improving coverage and reducing the occurrence of artifacts. The refined production algorithm provides improved spatial resolution, increased horizontal and vertical accuracy, and superior water body coverage and detection. The ASTER GDEM V2 maintains the GeoTIFF format and the same gridding and tile structure as V1, with 30-meter postings and 1 x 1 degree tiles. Version 2 shows significant improvements over the previous release. However, users are advised that the data contains anomalies and artifacts that will impede effectiveness for use in certain applications. The data are provided 'as is,' and neither NASA nor METI/Japan Space Systems (J-spacesystems) will be responsible for any damages resulting from use of the data.
As a contribution from METI and NASA to the Global Earth Observation System of Systems (GEOSS), ASTER GDEM V2 data are available free of charge to users worldwide from the Land Processes Distributed Active Archive Center (LP DAAC). The GDEM is available for download from. This ASTER product is available at no charge for any user pursuant to an agreement between METI and NASA. For more information about the GDEM, see the Validation Report:. Cfx manager software free download. Below are a couple of browse images derived from ASTER GDEM V1 globe map data sets.
The full data set can be downloaded from the links above. GDEM V1 Colorized Map (4,320 x 2,160) GDEM V1 Black & White Map (4,320 x 2,160) CL 97-1376 1,190,466 hits, since 3/1/2012. Updated: 12:00 PM Questions?
2015-10-13 Updated to include full range of resolutions up to 8K UHDTV. In an effort to enhance the knowledge of the video-making community, I have compiled a list of all true 16:9 video resolutions, including their associated standard when applicable, as well as when the resolution is divisible by 8, which is useful for limited video encoders. The table goes up to 1080p and includes common resolutions like that of a typical 27 inch 16:9 computer monitor and Super Hi-Vision. Note: If you’ve ever worked with SD content, you’ll notice that no resolution here fits the DVD standard.
That’s because DVDs were originally made to comply with the NTSC broadcasting resolution, which is a non-square pixel standard using the resolution of 720 by 480 pixels, stretched to accommodate either 4:3 or 16:9 content, never producing a true 16:9 resolution. (where ~ = repeat last three numbers to infinite) The conflict comes from the very fact that it is based on 720 by 480. You can’t get a ratio of 16:9 by keeping 480 lines of pixels. The closest you’ll get is 853.333~ by 480, which is not feasible. You could opt for either 853 or 854 by 480, but these aren’t true 16:9 resolutions, which is why they aren’t featured here.
16:9 = 1.77777777~ 853:480 = 1.77708333~ 854:480 = 1.77916666~ 1280:720 = 1.77777777~ Historically speaking, 720 by 480 is based on the digital conversion of the NTSC broadcast standard by Sony with the D-1 standard. Your conventional 4:3 CRT TV could be said to display non-square pixels in interlaced at a resolution of 720 by 480.
There’s two things you have to understand about this format: 1. It never displayed square pixels, so there was never a need to translated 4:3 content to, say, 640 by 480. It was never meant to display widescreen content, hence the aberration that is the DVD’s letter-boxing of 16:9 content, and the apparition of many approximations such as 854 by 480, or Apple’s all too wrong 848 by 480, none of which, by the way, have ever been standard. If you really want to stick to 480p, you could encode all your videos in 720 by 480 and let the software scale it to 16:9, which would at least allow a full-screen view to emulate true 16:9 with the higher pixel count, such as an upscaled 1080p on an HDTV. I have a question about the numeric ‘p’ labels. For instance, when one sees “480p”, why is the vertical resoltuion 400 (720/704×400) on 16:9? Yet, “352p” is 624×352 and “576p” is ~854×480?
