Slice Viewer

Slice Viewer Canvas

The Slice Viewer canvas displays a 2D cross-section of LiDAR point data at a specific location along the rail corridor. It renders slice points in relation to the structure gauge and rollingstock profile, and supports zooming, panning, and point selection. The toolbar provides tools to view and configure the display of the data shown on the canvas.

Co-ordinates

Both the SC0 co-ordinates and viewer co-ordinates are given.

The SC0 co-ordinates are the co-ordinates gathered from the measured points .SC0 files, and are calculated based on their position in relation to the left rail.

The Slice Viewer co-ordinates are the co-ordinates of the point on the canvas, plotted on cartesian plane.
