Slopes

Both man-made and natural slopes are commonly monitored for signs of instability using a combination of instrument types. These are handled in both manual and real time by the MissionOS platform with the flexibility to show a variety of calculated results in addition to the basic readings all of which can be shown in map and in section view as well as in 3 dimensions using the export to Sketchup capability. Other remote sensed data such as satellite interferometry, drone photogrammetric surveys and multispectral imaging can also be loaded, overlain and queried.
Commonly applied slope features include: Vectors the display of vectors and magnitudes on plan to show subtle changes which may indicate underlying slope movements. AGS borehole the inclusion of AGS boreholes and cross section views assists in the understanding of slope movements observed INSAR Raw satellite Interferometry and (PS) Particular Scatterer interferometry data can be uploaded and overlain on the mapping system Rate of change Instability is most often not indicated by pure displacement but by the rate of change and acceleration in displacement, orientation or tilt. These second order derived instruments can be setup and configured by the user and reported in a variety of ways. External data External data streams such as rainfall gauges, tide gauges or other environmental sources can be configured to be loaded Combinations Sometimes a single instrument alone does not tell the whole story and there is a need to combine instruments of different types either as plots or as ratios. Piezometer levels, vibration and slope movement/tilt are commonly connected. Construction For man-made slopes it is important to record the progress of construction and relate this to observations of movement in near real time.
