Leica GeoMoS Combined Total Stations and GNSS

Total stations and control points often must be placed in an area that may be subject to movements

With the combination of TPS and GPS the stability of the total stations and reference points can be effectively managed

GPS co-located to the total station and on one or more reference points can be used to update the position and orientation of the total station

GNSS receivers can also be used for direct monitoring of points of interest

Leica GeoMoS Web 1. Typical use case analyzing monitoring data

GeoMoS Analyzer

It can be time critical to get a clear overview about the actual deformation situation in the mine

Define the correct time period

Navigate to the critical points

A lot of different Plots must be produced (e.g. Longitudinal Displacement, Height Displacement)

Visualize real time monitoring data in GeoMoS Analyzer

Thousands of result records are produced in a large prism monitoring installation

It can be time consuming to analyze the data

25

Leica GeoMoS Web 1. Typical use case analyzing monitoring data

GeoMoS Analyzer

Results are transmitted to more powerful software packages to get better overview

In a daily interval the complete report must be produced

Sometimes there is high time pressure to prepare the complete information

The report can only be produced in the mine and access from outside is difficult Visualize real time monitoring data in

GeoMoS Analyzer

A package of time line plots, vector plots and reports must be produced with different software packages
