4.3.3.1.
Points
With the menu Calculate > Setting Out >
Points a setting out of points with known coordinates can be performed.
To
define the setting out and the orientation point, both, entering the point
number and clicking on the point in the graphic screen are possible.
The
functionalities of this menu correspond to those of the menu Input > Measurements.
By
pressing the <OK> button the
difference of the current position related to the setting out / orientation
point is calculated and shown numerically and in the graphic screen.
The
following data are shown:
|
LE |
Difference in the direction to the setting out / orientation point [m] |
|
QE |
Difference perpendicular to the setting out / orientation point [m] |
|
Ds |
Linear distance difference from current position to setting out point [m] |
|
DZ |
Height difference in the user system. |
|
TH |
True Heading: user's current direction of movement, determined by the receiver |
|
Az |
Azimuth from current position to setting out point [gon] |
The difference of the current position to the setting out / orientation point is
shown with a triangle. For TPS receivers the compass in the upper left corner
shows the true heading and the azimuth. If both arrows point in the same
direction the user is moving towards the setting out point. This feature works
only with movement.
To
save the coordinates of the current position click on the <Save>
button.
If
no orientation point is entered the differences shown relate to the position
where the last click on the <OK>
button occurred. With a new click on the <OK>
button the reference position can be updated at any time.
The
radio button Auto-Zoom can be set to <No>
in the Initial > Constants > GPS
menu. In this case the graphic screen of GART-2000®
CE shows always the user
defined zoom area, whereas the zoom area is always updated if Auto-Zoom
is activated.
On
pressing the button <Plot>, a polar representation of the setting-out situation is
presented. In this way, the point to be staked out can be located within the
vicinity.
Information
on left side on screen mean:
|
dE |
difference Easting |
|
dN |
difference Northing |
|
dZ |
difference of the Heights |
|
dS |
linear deviation |
The further buttons of the Setting Out dialog correspond to those of the
Measurement menu Setting out Point
with the total station.
When
the polar setting-out of points is performed with the aid of a total station,
the point to be set out must be entered in the dialog window under PntNo.
If the point exists in the point database, the setting-out elements are
calculated immediately and output under Set.
During calculation of the stake-out elements, reductions, instrument errors and
any residual estimations are taken into account. This calculation takes place
iteratively. If the set (standard) values cannot be calculated exactly, an error
message occurs specifying the attained accuracy in East, North and Height.
When
points without heights are set out, the height difference is assumed to be 0 and
thus the preset elevation to be 100 gon.
The
measurement can be triggered by various buttons. <All> triggers an
overall measurement, <BuildRef.> and <Ex-c> trigger a
measurement to a reflector. When using the <Ex-centers> button, the
amount of horizontal eccentricity is queried, and the amount of spatial
eccentricity is queried when <Ex-c> is used.
The
button "<>" switches
into the control mode in the case of automatic tachymeters.
On
pressing the button <Save Meas.>, the Measurement Registration
dialog appears automatically.
The
dialog can be quitted with <X>.
