Abstract: A slope stability monitoring apparatus which produces slope deformation maps that preserve measurements from fast moving small areas, slow moving small areas, slow moving large areas and fast moving large areas while minimising the effect of non-wall movement contamination, such as atmosphere and artefacts. Also a method of producing slope deformation maps by deriving a correction factor and applying the correction factor to correct for non-wall movement contamination.

Abstract: A Slope Stability Lidar that directs a beam of optical radiation into an area on a point by point basis, each point having an elevation and azimuth and a processor that acquires data and processes the data to compile direction data, range data and amplitude data for each point, segments the acquired data into blocks of data defining a voxel, averaging the acquired range data within the voxel to produce a precise voxel range value for each voxel, comparing voxel range values over time to identify movement and generating an alert if movement exceeds a threshold.

Abstract: A method for displaying an area on a display device, such as a graphical user interface (GUI), by displaying a front view of the area generated from front view data and a top view of the area generated from top view data according to a first line-of-sight; processing an interaction between an operator and one of the front view and the top view of the GUI; and displaying on the same display device an updated front view of the area and an updated top view of the area, wherein the updated front view and the updated top view are generated from the front view data and top view data according to a second line-of-sight, and wherein the first line-of-sight and the second line-of-sight have a common origin. The method is particularly useful for visualising, for example, an open cut mine. An apparatus for working the method is also described.

Abstract: The invention is a method of geo-positioning geographic data for visualization of a geographic area, particularly a mine site, and a device to work the method.

Abstract: A Work Area Monitor comprising a radar module mounted on a motorised vehicle. The Work Area Monitor provides early warning of slope failure in a work area by generating an alarm if movement detected in movement data derived from interferometrically processed radar images exceeds a threshold.
