Setting the GRID FACTOR
GRID FACTOR can reset in this menu mode.
For more information, refer to Section 8.1.1 “Setting the GRID FACTOR”.
Grid Factor can be applied to the following application programs.
It is also possible to cancel the Grid factor function by selecting "DON'T USE" in “SELECTING MODE” .
At this time the setting and selecting screens for Grid Factor will be omitted.
●
Data collection mode
When the NEZ automatic calculation (NEZ AUTO. CALC) is ON, Grid factor will be applied to the
coordinate data (Including PTL data) recorded into a coordinate data file when the RAW data is
measured and recorded. (In this case, Grid Factor is not applied to the RAW data recorded into the
measured data file.)
PTL (Point To Line measurement)
When executing PTL measurement mode, the NEZ Auto Calculation wil be turned on compulsorily and
Grid factor will be applied to the coordinate data.
●
Layout
Execution Layout (Including PTL measurement mode)
1. When displaying the difference (dHD) between grid horizontal distance to a layout point (HDg) on the
projection plane and measured ground horizontal distance to a prism point (HD) , Grid factor will be
applied to grid distance (HDg) in order to reverse-convert grid distance to ground distance.
2. After completion of a layout point, the displayed coordinate data will be applied to grid factor in order
to compare with surveying data and calculated data on the projection plane.
(NEW POINT-Side Shot)
In side shot method, a new point coordinate data will be applied to grid factor and the new point
coordinate data will be recorded into a coordinate data file.
(NEW POINT - Resection)
In resection method, when a new point calculated coordinate data is displayed or recorded, the new
point coordinate data will be applied to grid factor and the coordinate data will be recorded into a
coordinate data file.
●
MLM (Missing Line Measurement)
When selecting grid factor "USE G.F.", measured data will be applied to grid factor. At this time,
horizontal distance (dHD) and slope distance (dSD) will be on the projection plane.
●
AREA (Area calculation / Measured method)
When selecting grid factor "USE G.F.", measured data will be applied to grid factor. At this time, the
calculated area will be on the projection plane.
