From the panel on the left, select the array channels to stack on a section map. The order in which the channels appear in the selection box will be honoured on the map.

The selected array channels may have the depth information on-board, in which case the depth information of the first selected channel will be honoured for all. If the selected array channels do not have depth information on-board, you will be prompted for a depth channel.

If the data array has a base property of type other than depth or elevation, the property is entirely ignored. You must then supply a depth array defining the array vertical point locations.

Script Parameter: SECTION.SELECTED_CHANNELS

You have the option to plot sections from the current line, selected lines or all lines. The section data is gridded for plotting.

If the grids exist, you will be asked to overwrite them. If the survey line is folded upon itself, the section is generated as a pixel plot, rather than a grid; this is purely for display purposes.

Script Parameter: SECTION.LINES [D – Displayed, S- Selected, A- All]

If the above data channel(s) have depth information on-board, this entry is unnecessary and so will remain disabled.

If active, the list to select from is populated with array channels, of the same dimension as the selected data arrays. This channel specifies the vertical location of each of the data items to plot. The channel may contain values increasing up (elevations), or increasing down (depths). The onus is on you to properly pair the data array with a depth channel.

Script Parameter: SECTION.DEPTH

Select this box if the values in the depth array are in a right-handed coordinate system (positive Z up, such as elevation).

Script Parameter: CDI.NEGATIVE_DEPTHS_DOWN (default: 0)

Use this channel to define topography or a reference elevation. If defined, the depth or relative elevation values are added to the elevation values here to give the true elevation ("Z") of each data value.

Script Parameter: CDI.TOP_ELEVATION_CHAN

Specify a prefix for the output map(s). Map names are formed by concatenating this prefix with the line number, separated by an underscore.

Script Parameter: SECTION.PREFIX

The horizontal scale of all sections. The scale is calculated so that the length of the line is equal to the View width found under the Map Layout tab when you expand the More button.

Click the calculate button to recalculate the scale, based on the currently defined view width and line length.

If you make the scale smaller than the default setting scale, the default width of the map will not be wide enough. In this instance, the physical length of the section map will be adjusted to honour the user defined scale and the default indicated in the Map layout tab is overridden.

Script Parameter: SECTION.SCALE

A vertical exaggeration of 1 generates a section map with an aspect ratio of 1.

If you would like to stretch the vertical scale, click the calculate button; this parameter will be set to a ratio that will produce a section map where the depth is half the size of the horizontal extent.

Script Parameter: SECTION.VERTICAL EXAG

The surrounds can be generated with default settings. If you do not desire surrounds on the section maps, select None. To further customize the section surround, select Custom and the Draw Section Surround dialog will appear.

Script Parameter: SECTION.SURROUNDS [0 – None, 1 – Default (default), 2 – Custom]

By default, the entire horizontal extent is plotted. Click the calculate button to populate this entry with the minimum horizontal extent to show on the map. You can then proceed to modify it.

Script Parameter: SECTION.START

By default, the entire horizontal extent is plotted. Click the calculate button to populate this entry with the maximum horizontal extent to show on the map. You can then proceed to modify it.

Script Parameter: SECTION.END

By default, the entire vertical extent is plotted. Click the calculate button to populate this entry with the highest value of the vertical extent.

Script Parameter: SECTION.TOP_ELEVATION

By default, the entire vertical extent is plotted. Click the calculate button to populate this entry with the lowest value of the vertical extent.

Script Parameter: SECTION.BOTTOM_ELEVATION

This entry is populated with a list of the selected channels and is not editable. The next two parameters pertain to the channel on display in the box and have this channel name as part of the script parameter name. This entry consists of a list of the selected channels separated by semicolons.

Script Parameter: SECTION.SELECTED_CHANNELS

For colour tables that do not include their own colour transform mapping ranges to specific colours, select the colour method to produce the section of the channel displayed in this tab.

Script Parameter: SECTION.METHOD_ChannelName [0: Default, 1: Linear, 2: Normal distribution, 3: Histogram equalization, 5: Log-Linear]

Select the colour scheme for rendering the grid or pixel plot of the channel displayed in this tab. If you mouse over the colour scheme entry, a tooltip will display the name of the colour table in its folder. To modify the selection, click on the colour entry and then navigate through the scheme categories.

Script Parameter: SECTION.ZONEFILE_ChannelName

Set the brightness for rendering the grid or pixel plot of the channel displayed in this tab. The normal brightness is defined at 0. You can change the brightness from -100 (black) to 100 (white) using either the slider bar or by entering an exact value.

Script Parameter: SECTION.BRIGHTNESS_ChannelName

The colour scheme can be used in reverse order. Check this box to reverse the order for the channel on display above.

Script Parameter: SECTION.REVERSE_ChannelName [0-No | 1 - Yes]

For display purposes, by default, the grid is first interpolated to a smooth image at the screen resolution. If you prefer to honour the grid resolution, the image will appear pixelated and the colour will change at the actual grid interval rather than the screen resolution. Formerly, this functionality was found under the image filters as " No smoothing (GRD)". Check this box to forgo the smoothing.

Script Parameter: SECTION.PIXEL_ChannelName [0-No | 1 - Yes]

A number of methods are offered to display the colour section image. The pixel plot is applicable only when the trace of the section is folded and a Geosoft grid cannot be generated from it. The same gridding method will be used for all the selected channels.

Script Parameter: SECTION.DISPLAY_METHOD [MINCURV_GRIDDING, INVERSE_DISTANCE_GRIDDING, NONE, PIXEL_PLOT, DIRECT_GRIDDING]

Depending on the display method, it is possible to set both the vertical and horizontal cell size (e.g. for Inverse Distance Weighted Gridding and Direct Gridding), or just the Horizontal cell size (minimum curvature gridding uses square grid cells), or neither (pixel plot cell sizes vary in both dimensions depending on the data separations).

Script Parameter: SECTION.CELLSIZE_X

Script Parameter: SECTION.CELLSIZE_Z

This box appears if you have chosen one of the following gridding methods: inverse distance weighting or minimum curvature gridding. These are the gridding methods for which you can supply gridding parameters.

If you have chosen one of the methods stated above, you could either supply the same gridding parameters for all channels or supply separate gridding parameters for each selected channel.

In the case of the above gridding methods, if you would like to override any of the default gridding parameters, first you must decide if you will be supplying the same gridding parameters for all selected channels or if you will individually customize them.

To supply the same gridding parameters for all channels, select Default Channel Settings and proceed to supply the parameters. In this case, the parameters you define will be saved in the selected gridding parameter space.

Otherwise, from the drop-down list select the channel for which you will proceed to supply parameters. In this case, the parameters you define will be saved in a parameter space with the following syntax:

Script Parameter: SECTION.ChannelName_GriddingMethod_ParameterName

Where:

• ChannelName is the name of the channel the parameter belongs to

• GriddingMethod is contextually set. It is either MINIMUM_CURVATURE or IDW

• Parameter Name is the contextual gridding parameter

Clicking this button will open a contextual dialog to supply the parameters for the above selection. To supply the parameters of the next selected channel, simply select it from the above drop-down list.

Set the width and height, in cm, of the section view. These values are initialized to the values contained in the selected page layout.

Script Parameter: SECTION.WIDTH

Script Parameter: SECTION.HEIGHT

Set the 4 margins in cm, of the section view. These values are initialized to the values contained in the selected page layout.

Script Parameter: SECTION.TOP_MARGIN_CM

SECTION.BOTTOM_MARGIN_CM

SECTION.LEFT_MARGIN_CM

SECTION.RIGHT_MARGIN_CM

Only active for stacked sections; indicates the distance between adjacent section in cm.

Script Parameter: SECTION.MARGIN

Select the ground elevation channel, on the same axis as the elevation data. This can be, but does not have to be the same as the Elevation channel.

Script Parameter: SECTION.TOPOGRAPHY

Select to draw the trace of the topography along the top of the section(s).

The Line thickness and Line colour for the topography trace will be enabled below.

Script Parameter: SECTION.TOP_ELEVATION
