From 1901 to 1911, the USCGS established several triangulation networks across the country which had different origins. In 1911, these different networks on different datums and with different origins were consolidated into one nationwide network and the Luzon Datum was established with triangulation station Balanacan as its datum origin.
A caliber conversion device is a device which can be used to non-permanently alter a firearm to allow it to fire a different cartridge than the one it was originally designed to fire. The different cartridge must be smaller in some dimensions than the original design cartridge, and since smaller cartridges are usually cheaper, the device allows ...
The World Geodetic System (WGS) is a standard used in cartography, geodesy, and satellite navigation including GPS.The current version, WGS 84, defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM).
This template is primarily intended for the mass conversion of coordinate sets in lists. For individual sets of coordinates, the online conversion tool provided by Swisstopo may be preferred. For extended documentation, see de:Vorlage:CH1903-WGS84 , from where this template has been copied.
A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used type of the various spatial reference systems that are in use, and forms the basis for most others.
The dimensions of the three arcsecond tiles are 1201 x 1201. The original SRTM elevations were calculated relative to the WGS84 ellipsoid and then the EGM96 geoid separation values were added to convert to heights relative to the geoid for all the released products. [5]
A transverse Mercator projection. The transverse Mercator map projection (TM, TMP) is an adaptation of the standard Mercator projection.The transverse version is widely used in national and international mapping systems around the world, including the Universal Transverse Mercator.
WGS84 angle to distance conversion: Image title: Length of one degree (black), minute (blue) and second (red) of latitude and longitude in metric (upper half) and imperial (lower half) units at a given latitude in WGS84 by CMG Lee. For comparison, dotted lines denote corresponding lengths assuming a spherical Earth.
