Inline IP Stacked Section

Use the Inline IP Stacked Section menu option (IPPSSTAK GX) to plot a stacked pseudo-section map, including sections from the selected lines, plotted on a plan map.

Inline IP Stacked Section dialog options

Channel to plot

Select a channel from the list. Although some pre-selection is done when creating the channel list (removing X, Y, Z, etc.) it is up to the discretion of the user to select a "reasonable" pseudo-section channel.

Script Parameter: IP.STAKCHAN

Section spacing

Select the format for creating the stacked section plot. Select either Map base spacing, or Equal spacing (see Application Notes below).

Script Parameter: IP.STAKTYPE (0:Map Based, 1: Equal)

IP Plot Control file

Specify the name of the control file for plotting the pseudo-sections. The default file type is ".ipi". The same control file may be used for both the Inline IP Pseudo-Section and Inline IP Stacked Section, as they share a large number of parameters.

Script Parameter: IP.STAKCON

Output map name

Specify the name of the created map file. If the map does not exist, the New Map from X, Y is run to set up the map scaling, using the database extents as defaults.

Script Parameter: IP.STAKMAP

[Modify]

Select the Modify button to edit the selected control file, or create a new one, using the IPSTAKCON GX wizard.

Application Notes

Stacked Section Plot Types

There are two types of stacked section plots to choose from.

If you select Map base spacing, the sections always plot horizontally or vertically on the map, with the position scale along the original locations. The spacing between the sections corresponds to the spacing between the lines in the survey, based on the scale used along the line for plotting stations. For instance, if your lines were L0, L100 and L600, you would get two lines plotting close to each other, and one separated by some distance from the other two. The advantage of this setup is that the sections are displayed in a manner which corresponds to their geographical positions. The disadvantage of this is that the sections may obscure or overlap each other if the line to line spacing is small in comparison to the maximum N-separation plotted, or if there is a mix of N-S and E-W lines. This problem can be partially alleviated by setting a vertical exaggeration to the sections with a value less than 1.0.

If you select Equal spacing, the spacing between the sections is held constant, and made large enough so that the full sections are guaranteed to be visible, without the need to resort to a vertical exaggeration of the sections. Sections are aligned horizontally based on the along-section locations. If there is a mix of N-S and E-W lines, then they will still line up using the station locations along line.

  • Because of the various modifications in the output grids necessary to display map-based N-S sections in a rotated format, it is not possible to create a 3D view from a map-based stacked section map.
