your survey without solving a localization. You then submit
the post processing data file to the NGS’ OPUS service and
get back the calculated local coordinate. You then wish to
adjust the survey to match the calculated coordinate for your
base.
• You start a survey with your base on a new autonomous
position. You occupy one or more NGS control monuments
during the survey, but you do not have the data sheet with
the published north, east, elevation coordinate in the field.
You get back to the office and download these data sheets
from the NGS web site, and you wish to solve a localization
using these points as control.
• You start a survey with your base on
an autonomous position. You occupy
one or more control points during the
survey, but you do not have the
proper north, east, elevation
coordinate in the field. You get back
to the office and you calculate the
proper coordinate for these points by
some method such as an adjustment
of post processed baselines, or from
another crew’s job file measurement
to the same point. You then wish to
solve a localization using these points as control.
1. Open the Survey > Import GPS Control screen.
2. Select the points you wish to make into GPS control points. You
must select points that have geodetic (LLH) coordinates.
3. Select a method to input the source for the accurate location of the
control point
