Offsets in Topo Survey (Optical)
Offsets in topographic survey (optical) provide extended possibilities for determining the coordinates of points that are not available for direct measurement, hidden, or even physically non-existent. This is realized through measurements to accessible locations, special surveying techniques and background calculations. MAGNET Field offers multiple offset modes that combine advanced interface tools for easy and fast collection of ancillary data and calculation routines for offset measurements.
To enable the desired offset mode, click
in the top left corner of the Topo Survey (Optical) dialog and click Measure to expand the menu with available offsets:
Note: Offset modes are available only for the Direct measurement method. Prior to enable one of the offset modes, ensure this method is currently used. If necessary, select it in the Survey Setting dialog (by clicking
in the title bar of any optical topo survey dialog).
- Horizontal Angle Offset - to determine a point using the horizontal angle from one point and the distance to another.
- Horz / Vert Angle Offset - to determine a point using the horizontal and vertical angles.
- Distance Offset - to determine a point by adding or subtracting distances, horizontally and vertically.
- Hidden Point - to determine a point with a slanted rod touching this point.
- Two Line Intersection - to determine a point by the intersection of two lines, which are specified by measuring two points on each of the two lines.
- Line and Corner - to determine a point on the corner by the line defined by two points and a horizontal angle measurement.
- Line and Offset to determine a point in a distance from the line defined by two points.
- Plane and Corner - to determine a point on the plane, measured from the three available points, and horizontal and vertical angle measurement to an inaccessible point.
- Column Offset - to determine a center point (inaccessible point) inside the column or tree using the distance and angle measurements.
- Vertical Search Offset - to determine a point using the horizontal angle of the ferrule of the pin-pole and the vertical angle and slope distance of the prism (available for Robotic TS).
