Compute Position Error

by: Glenn D. MacGougan.

Submit a text file (whitespace or comma delimited) with the following information present (geodetic coordinates, WGS84 assumed):
epoch(s) latitude(decimal degrees) longitude(decimal degrees) height(m)

Position Data File:

e.g. In this 'file', the time field is 1 (0 based index), the latitude field is 3, the longitude field is 4, and the height field is 5
1024 0.0 2222 51.500001 -114.212346 1002.5
1024 1.0 1111 51.500002 -114.213471 1001.8
1024 3.0 1001 51.500004 -114.213473 1001.8
1024 4.0 1011 51.500008 -114.213472 1001.8
...
1024 100.0 8888 51.500009 -114.212348 1000.1
etc

Position Data File Field Index Information

time field (0-N-1)
latitude field (0-N-1)
longitude field (0-N-1)
height field (0-N-1)

Compute the position error and plot the errors to +/- metres with respect to the reference point.
