Internal Reliability¶

Use this dialog to perform an internal reliability analysis for a selection of points.

Where to Find the Dialog¶

On the Survey toolset in terrain model drawing, select the Internal Reliability icon.

Calculation Type¶

You can choose between three calculation types:

Planimetric
Elevation
3D

Planimetric and elevation are calculated together when you select the 3D calculation type.

Analysis Parameters¶

Free network is the default choice in the analysis, but it can be changed under analysis parameters. The purpose of the free network is that the measurements alone determine the network's shape and size.

The program locks the necessary reference points. The following symbols show which points are released:

Arrow up: Released in planimetric

Arrow down: Released in elevation

Arrow up/down: Released in planimetric and elevation
