Segy Profile Object

The Seismic SEGY profile import is very simple. There is no time to depth conversion and it is up to the user to specify the top and bottom elevation of the seismic profile, which is then “streached” accordingly. This corresponds to a time to depth conversion with a constant velocity.

The positions of the seismic SEGY profile is read from the SEGY trace headers, and a profile is constructed with the seismic draped on it. The user may after import change the default vertical positioning in the Object inspector of the profile, where it is also possible to change colorscales etc.

Note – when you open the profile in a profile view, you have the option in the right click mouse menu to enable dynamic bitmap zoom. This will load the SEGY data into memory, and give you high resolution when you zoom in the seismic SEGY profile. This performs slower but you gain full resolution of the seismic.

To import the Seismic SEGY profile, simply use the “Add Data Wizard” and select the SEGY file.

A Seismic SEGY Profile is basically a fence object with Blanking capabilities. A Seismic SEGY profile can also be shown in a Profile Window. See the description of Blanking. In a profile the center plane fence may or may not be visible. When the profile blanking is active solid layers may be shown at the same position as the profile fence. In that case the profile fence should be turned off.

Multiple profile objects below a common group object is defined as a profile group. Properties for a profile group can be modified using the Multiple Profiles Properties dialog. Profiles below the root “Objects” node are added to maps as single profiles. Profiles below group objects are added to maps in groups. A group of profiles may be generated with the Profile Generator.

A profile may also shown in a traditional 2D fashion where data are projected onto a vertical plane, see the description for Profile Window.

Name: Object name as seen in the Object Manager
Visible: Show/Hide the object
Outline: Shows a dashed outline of the fence
Blanking Active: The Profile blanking is active.
Hide Crossing: If this option is selected in a specific profile, the profile crossing for this specific profile will not show on other profiles.
Rounded Buffer Ends: When the Profile blanks surfaces and other data the two ends of the profile are round if this option is selected.
Solid Layer At Polyline: Solid layers will be rendered along the 3D Profile fence. When this option is checked the fence in the 3D Profile should not be visible.
Solid Layer At Buffer: Solid layers will be rendered along the default buffer outline of the 3D profile object.

Fence
Manual: Set the top and bottom elevation manually
Automatic: Set the top and bottom elevation automatically (read from Segy file)
Top Elevation: Elevation of the top edge
Bottom Elevation: Elevation of the bottom edge

Remark
General purpose remark

Segy Dataset: Selects the Segy dataset .

The list shows the XY nodes used to define the path of the fence.
Fence Node Simplification: Simplifies the amount of nodes in the original Segy profile.
Precision: Precision factor which is inspected visually
Calculate Nodes: Calculates the nodes given by the precision factor
Export: Save nodes in CSV files

Properties
Opacity: Degree of opacity. 1=fully opaque, 0=fully transparent (enabled when Blending Mode = Transparency)
Advanced: Shows the advanced Material Editor
Horizontal Bitmap Resolution (pixels): Bitmap resolution in pixels. Large bitmaps consumes large amounts of system resources. Therefore, in general bitmaps should not be larger than strictly necessary.
Color Plot: Makes a color plot of the bitmap.
Active: A color scale active on the bitmap, activates the Color Scale Editor

Visibility
Visible: Show/Hide the labels
Visible Distance: Labels are shown within this distance from the camera. Keep low to improve performance.
End Nodes Only: Labels are only shown for first and last node.

Scale
Horizontal: Horizontal text scale factor
Vertical: Vertical text scale factor
Depth: Text depth scale factor. Effective only when extrusion is greater than zero.

Position And Angle
Rotate Towards Camera: Labels are rotated towards the active camera. Rotating a lot of labels will have a negative impact on performance.
Rotation Angle: When the labels are not rotated towards the camera the label will have this rotation angle.
Vertical Offset: Distance from the labeled object to the bottom of the label.
Vertical Angle: Label rotation from horizontal (counter clockwise).

Font
Font: Text font
Color: Text color
Text Height: Height of text (font size)
Extrusion: 3D text depth.

Text Alignment
Horizontal: Horizontal text alignment
Vertical: vertical text alignment

Each blankable object in the scene is shown in the list. A buffer radius can be specified for each object.

Certain points based data may be blanked using data IDs instead of a radius. This is what the IDs column is for. This feature is currently only used in conjunction with the GeoScene3D GeoModel ArcGIS extension.

Window
