Survey Corner & 2 Lines .
The Corner and 2 Lines screen is used to store
a point at the corner of a structure using a
reflectorless total station where a direct
measurement to the point is not possible, but
two points on two intersecting lines can be
shot.
Foresight: is the name of the point that will be
stored.
Description: is the description for the point
that will be stored.
HR: 0.000: shows that no rod height will be
used with this routine since all shots are direct
reflectorless.
Shoot Line 1 : will prompt you to take two shots on Line
1, which intersects with Line 2 at the point you want to
store.
Note: Each shot for a line can be in any location on the
same line. (Shot 1 can be to the left or the right of Shot 2.)
Shoot Line 2 : will prompt you to take two shots on Line
2, which intersects with Line 1 at the point you want to
store.
Note: After all shots are done, the computed elevation is displayed
for the new point. You can either enter a different elevation or tap
to accept the computed elevation.
Backsight : opens the Backsight Setup screen (Page R-118) where the
current backsight can be modified.
