Scan P3 (ScaP3)

Type: Interactive Application

 

Drives the Zeiss P Series stereoplotters along user-defined scan lines for XYZ profiling. During scanning, the operator keeps the floating mark on the ground and points are stored by distance and/or elevation change. The speed the instrument travels is determined by the speed knob.

ScanP3 Parameters

ScanP3_image002

Layer for scan lines

Specifies the layer in which to store scan lines as VrOne lines.

Scan line shift width

Once the first scan line has been defined, multiple scan lines may be read based on its start point and azimuth. The shift width defines the distance between scan lines. The Move+ and Move- buttons in the Begin Scan menu move the scan start point by this distance.

Minimum recording distance

Defines the distance along the scan line to store points during scanning. The resulting distance may not be exact depending on the speed of the stereoplotter. This parameter should be slightly smaller than the stereoplotter's specification to ensure a sufficient number of points. The batch routine Grid Lines (GriLin) may be used to place precisely spaced points on existing lines.

Delta Z recording distance

Specifies delta elevation at which to store points during scanning. Depending on the speed of the stereoplotter, the distance may not be precise. This parameter should be slightly smaller than stereoplotter specification to ensure a sufficient number of points. Setting this parameter to zero will turn off Delta Z point collection.

Z control

Defines the location of Z motion during scanning. Options are Footdisk, Handwheel and P3 Y Tablet motion. If the P3 Y Tablet motion is selected, a positive y P-Cursor movement will lower the elevation and a negative y P-Cursor movement will raise the elevation.

Beep when a point is stored?

Specifies whether to emit the Vr Normal Beep wave sound each time a point is stored during scanning. The Normal Beep sound may be configured in the Vr Configuration program (VrCfig).
