The arrival of the 1-m telescope arose much joy and was duly celebrated. Important for our sub-arcsecond resolution ability is the in-house development.

In the image of M-34, what does 1 arcsecond correspond to in light years? Answer: A) For the Moon: L = 1 arcsec/206265 x (384,000 km) = 1.86 or 2.0 kilometers.

Also, can you be more specific about what is unusable about the results you are getting? – matt wilkie Sep 8 '10 at 16:18. i beleive 1arc-second is roughly 30m resolution whereas 3 arc-second 90m. LiDAR-based elevation rasters from the National Map are 1/9 arc-second products (about 3-meter resolution) while elevation based on 10-meter USGS DEMs are 1/3 arc-second products. There may be 1/9 arc-second National Map elevation products that are not based on LiDAR (metadata should described source of particular data). SRTM 1 Arc-Second Global (Digital Object Identifier (DOI) number: /10.5066/F7PR7TFT) elevation data offer worldwide coverage of void filled data at a resolution of 1 arc-second (30 meters) and provide open distribution of this high-resolution global data set.

Fort Bragg, California 1/3 arc-second NAVD 88 Coastal Digital Elevation Model DEMs range from 1/3 arc-second (~10 meters) to 3 arc-seconds (~30 meters).

This allows you to attribute features using the units listed on the chart and then convert them in a batch process. Conversion of arc seconds to inches depends on the distance that is being measured.

Many translated example sentences containing "arc of" – Swedish-English in the vicinity of the sampler (normally some metres away from buildings, balconies, defined in point 2.2.1 of Annex II and on the arc perpendicular to this segment. in a second processing stage by fusion in an electric arc furnace, come under 

If you want an exact answer, you would need to estimate the radius of the A second of arc, one sixtieth of this amount, is roughly 30 metres (98 feet). The exact distance varies along meridian arcs or any other great circle arcs because the figure of the Earth is slightly oblate (bulges a third of a percent at the equator). Said differently, an arc-second represents the distance of latitude or longitude traversed on the earth's surface while traveling one second (1/3600th of a degree). At the equator, an arc-second of longitude approximately equals an arc-second of latitude, which is 1/60th of a nautical mile (or 101.27 feet or 30.87 meters). One second of longitude is one sixtieth of that amount: about 31 meters or 100 feet. However: Arc-seconds of latitude remain nearly constant, while arc-seconds of longitude decrease in a trigonometric cosine-based fashion as one moves toward the earth's poles. As part of its National Map initiative, the USGS has developed a suite of elevation data products derived from traditional DEMs, lidar, and other sources.

At the equator, an arc-second of longitude approximately equals an arc-second of latitude, which is 1/60th of a nautical mile (or 101.27 feet or 30.87 … A second of arc or arcsecond is a unit of angular measurement which comprises one-sixtieth of an arcminute, or 1/3600 of a degree of arc or 1/1296000 (approximately 7.7×10-7) of a circle. It is the angular diameter of an object of 1 unit diameter at a distance of 360×60×60/ (2pi) (approximately 206,265 units), such as (approximately) 1 cm at 2.1 One second of longitude is one sixtieth of that amount: about 31 meters or 100 feet.

For the earth (which other users could note is the planet that most people on earth study), one arc-second is approx 30m. If you want an exact answer, you would need to estimate the radius of the For example, the radius of the Earth is approximately 6,371,000 meters. So, on the Earth, one arc-second is approximately.
