According to Wikipedia https://en.wikipedia.org/wiki/Earth-centered%2C_Earth-fixed_coordinate_system: in today's modern age of navigation and spatial referencing, there's a key player that often goes unnoticed: the Earth-centered, Earth-fixed coordinate system, more commonly known as ECEF. This sophisticated system, akin to a cosmic GPS, allows us to pinpoint locations with incredible precision. Picture this: a cartesian grid that not only encompasses the Earth's surface but also delves deep into its core, reaches high into the atmosphere, and extends into the surrounding outer space. Through X, Y, and Z measurements from the Earth's center of mass, ECEF opens up a world of possibilities for mapping and exploration.
The WebApp Koordinat2 here on https://dominoc925-pages.appspot.com/webapp/koordinat2/default.html has been enhanced to include conversions between ECEF and various other geo-coordinate systems.
The following shows how to use convert ECEF to/fro longitude, latitude, altitude WGS84.
Define ECEF as the Primary coordinates (input)
- Open a browser to the Koordinat2 web app url https://dominoc925-pages.appspot.com/webapp/koordinat2/default.html.
The Koordinat2 web app home page is displayed.
- In the Primary coordinates input card, click the gear icon.
The Primary coordinates selection dialog box appears with a list of favorite coordinate systems.
- Click the ECEF item from the favorite list, or search for it by clicking the Search icon and typing in ECEF.
Define WGS 84 as the Secondary coordinates (output)
- In the Secondary coordinates card, click the gear icon.
The Secondary coordinates favorites list is displayed.
- Click on the WGS 84 item from the favorites list, or click the Search icon and typing in WGS 84 to search for it.
Enter ECEF coordinates
- In the Primary coordinates card, type in the X, Y, and Z ECEF values.
The ECEF values are converted to the secondary WGS 84 coordinates. A marker appears on the map.
