Use the TBC Monitoring module commands to supplement manual/campaign-based monitoring projects by comparing coordinates for points that have been measured in the field on multiple occasions over a period of time and imported into TBC (where they are processed and adjusted as necessary) so the cumulative data can be used to track point movement. This workflow provides an excellent method for monitoring earth or structure movement. 

Following are the basic steps for this workflow. For more detailed instructions, see Monitor Point Movement.

Steps:

Commands:

1.

Create a project for the first (reference) epoch.

The reference epoch is required to establish a baseline of point coordinates to which coordinates computed in subsequent epochs are compared to show point displacement.

Note: If you have not already done so, you must be logged in to Trimble Identity so that TBC has access to the Trimble Connect cloud, where monitor point data will be stored and synchronized.

2.

Create a project for each subsequent epoch.

Each subsequent epoch in your Trimble Connect monitoring project will compare that epoch's point coordinates with coordinates in the reference epoch and other previous epochs in the monitoring project to show point displacement over time.

3.

Set Warning and Alarm thresholds for monitored points.

Specify displacement threshold values that, if exceeded, will result in displacement vector arrows displayed in graphic views to display in yellow (point displacement exceeds one or more Warning thresholds) or red (point displacement exceeds one or more Alarm thresholds). These colors are also used in Monitoring Point Charts when either the △2D, △3D , or △Elevation option is selected exclusively.

4.

View monitored point displacement.

View monitored point displacement information in any of the following views:
- Properties pane
- Plan View and 3D View
- Monitoring Point Chart
- Monitoring Points Spreadsheet
- Monitoring Report

Optionally, use the Monitoring Epochs Manager to manage monitoring data by performing any of the following tasks in a single, easy-to-use dialog:
- Change the reference epoch.
- Change the timestamp of an existing epoch.
- Delete an epoch.
- Delete a point from an epoch.
