The Polar Geospatial Center (PGC) was founded in 2007 and was originally called the Antarctic Geospatial Information Center (AGIC). In its early days, the AGIC's goal was to provide basic mapping and GIS services for the United States Antarctic Program (USAP), and was only a two-man project.
The Principal Galaxies Catalogue (PGC) is an astronomical catalog published in 1989 that lists B1950 and J2000 equatorial coordinates and cross-identifications for 73,197 galaxies. It is based on the Lyon-Meudon Extragalactic Database (LEDA), which was originally started in 1983. [2] 40,932 coordinates (56%) have standard deviations smaller ...
Grid-based transformations directly convert map coordinates from one (map-projection, geodetic datum) pair to map coordinates of another (map-projection, geodetic datum) pair. An example is the NADCON method for transforming from the North American Datum (NAD) 1927 to the NAD 1983 datum. [ 26 ]
Has geographic coordinates for airports, heliports, and other facilities which have an IATA or ICAO code. You can also search by location name. Plexscape WS: Google Maps tool – Coordinate converter: Online application to acquire coordinates for any place on Earth. Supports more than 3,000 coordinate systems and 400 datums worldwide.
Blue Marble's first software product, the Geographic Calculator, [2] was developed in 1992 and released in 1993. The Geographic Calculator is a coordinate conversion library with a database of coordinate mathematical objects including projections, coordinate systems, datums, ellipsoids, linear and angular units.
A WKT format is defined to describe the operation methods and parameters used to convert or transform coordinates between two different coordinate reference systems. The WKT 1 and WKT 2 formats are incompatible regarding coordinate operations, because of differences in the modelling. [13]
This template is designed to convert a set of Swiss coordinates into either the corresponding WGS84 decimal latitude or longitude.It is intended to facilitate the usage of geodata (see {{}}) in articles about subjects for which only Swiss coordinates are readily available.
NGC 1356 is a barred spiral galaxy located in the southern constellation of Horologium. [2] It was discovered by English astronomer John Herschel on Dec 23, 1837. [3]At a distance of 550 million light-years (170 Mpc) away from the Sun, [1] NGC 1356 is superimposed over an much more distant galaxy (also a barred spiral), PGC 95415, which is approximately 300 million light-years (93 Mpc) more ...
