Interactive Application

If you are using peak-finder through the interactive application you will see a window with visualizations and ui controls. The visualization contains both a section of data along a single line and a plan view to locate the chosen and adjacent lines and anomaly picks in cartesian space.

The ui controls section is divided into three subsections:

Detection Parameters

The detection parameters are those that the peak-finder application uses to tune the characterization and detection of anomalies within the data. Most of these are already described in the Methodology section. Follow the links for detailed descriptions of each parameter.

Visual Parameters

This section controls the appearance of the plotting area.

N Outward Lines

Number of lines to display on either side of the selected line in the plan view. The Survey figure option must be selected to see the effect of this parameter.

X-axis Label

Updates the label on the data section view x-axis.

Fig. 4 The x-axis label is updated to reflect the selection.

Y-axis Scaling

Updates the scaling of the y-axis of the data section view

Linear threshold

When Symlog is chosen for Y-axis scaling, this parameter will set the region in which linear scaling is used.

Plot residuals

Switches on and off the residual visualization that shows the difference between the raw and smoothed data. See the Smoothing section for more details.

Plot markers

Switches on and off the markers outlining the character of each anomaly

Fig. 7 Markers are used to indicate the left and right edges, the center, and the inflection point in curvature of each anomaly.

Output Parameters

Create trend line

Run a trend line detection algorithm on the result of the Peak Finder algorithm. Results are stored as a curve object in the geoh5 file with the same group ID as the Peak Finder result.

Save as

property PeakFinderParams.ga_group_name: str | None

Name of group to save results to.

Name of the group in the geoh5 file where the results will be saved. The default is peak_finder.

Export

Run the algorithm with the parameters selected and save the result to geoh5.
