GPS Vectors and Total Station report
Following is a report generated
from a project that combined GPS vectors and total station data.
Notice that the report is very similar to the GPS vector only
project report. Explanations of the report are included in
the report and are in bold, normal text.

Notice that in this example geoid
modeling was used. Notice that the ellipsoid elevation is displayed
with the latitudes and longitudes. Orthometric elevations are
displayed with the SPC83 grid coordinates.

Notice that in the 3-D model
distances are not reduced to horizontal or grid. Slope distances
are reduced to mark to mark distances. A Mark to mark
distance is the computed slope distance from the monument to
monument.
