BUILT-IN MATHEMATICA SYMBOL
GeoPosition
- GeoPosition[pos, datum] converts from any type of geographic position. The following coordinate types can be given: GeoPosition, GeoPositionXYZ, GeoPositionENU, GeoGridPosition.
- GeoPosition[GeoPosition[...], datum] converts between datums.
- Standard datums can be specified by name.
- Typical named datums include:
-
| "ITRF00" | international Terrestrial Reference Frame 2000 |
| "NAD27" | North American Datum of 1927 |
| "NAD83CORS96" | North American Datum of 1983 (CORS96) |
- The complete list of named datums and reference ellipsoids is given by GeodesyData[].
- GeoPosition coordinates are assumed to have a time coordinate equal to the reference epoch date of the datum.
- GeoPosition[{
, 
, h, t}] includes a time, given as a date t in decimal years.
Geodetic position in the default reference frame:
| Out[1]= |  |
A position that explicitly refers to the ITRF00 reference frame:
| Out[1]= |  |
Convert this position to NAD 83 (CORS96) coordinates:
| Out[2]= |  |
Convert to Cartesian geocentric coordinates:
| Out[3]= |  |
Convert back to geodetic coordinates:
| Out[4]= |  |
Convert back to ITRF00:
| Out[5]= |  |
