Note: The two corner points in the Angle Grid method must

encompass the area to be scanned – they do not have to be on the

surface itself since no distances are measure to these points.

The Horizontal Angle Interval and Vertical Angle Interval fields are used

to configure the spacing between each shot taken within the

boundaries of the predefined surface. The smaller the angles entered

here, the more shots will be taken, resulting in a more detailed

surface, but while taking more time to complete.

c. Enter the desired horizontal angle to turn between

each shot of the surface being scanned in the

Horizontal Angle Interval field.

d. Enter the desired vertical angle to turn between each

shot of the surface being scanned in the Vertical Angle

Interval field.

Angle Grid Advantage and Disadvantages

The advantage of using the Angle Grid method is the corner points

that define the perimeter of the surface must only encompass the

surface and do not have to be on the surface itself.

The disadvantage of the Angle Grid method is the spacing between

each shot is based on the angles provided. The spacing is therefore

affected by the distance between the total station and the surface

being scanned. Finding a suitable angle interval may require some

trial and error.

4. The HR should almost always be left at the default value of

zero since all shots taken are reflectorless (no rod).

5. The Show Outline button is useful when the laser pointer is

activated on the total station. Tapping this button will

instruct the total station to "draw" a box around the

perimeter.

6. The Show Unit button is similar to the Show Outline button,

except it will draw a box around a single horizontal/vertical

interval. This is useful to verify your interval results in

satisfactory spacing.
