Note: This module is deprecated and is retained only for backward compatibility with existing workflows. It is not recommended for use in new projects.
This module updates the elevation (topography) values assigned to each bin point along a crooked seismic line. It reads surface topography from a bin grid and interpolates the ground elevation at each bin's horizontal position (X, Y). The result is a bin point vector in which every bin carries an updated Z coordinate reflecting the actual surface elevation at that location.
Accurate surface elevations on bin points are required for computing statics corrections and for correctly displaying the geometry of a crooked 2D line relative to the terrain. This module is used in crooked-line geometry workflows where the bin grid already contains a pre-loaded topography map and the bin positions need to inherit those elevation values before downstream processing (such as statics computation).
This module has no user-configurable parameters. It operates fully automatically once the required input data items are connected. Three visualization panels are available to verify the result: a plan-view map of the crooked line, and side-view profiles of the input and output topography along the line.
The set of bin points defining the crooked 2D seismic line geometry. Each bin point carries horizontal coordinates (X, Y) and a Z value. This module reads the X and Y position of every bin point and uses them to look up the corresponding elevation from the topography map. The original Z values in this input are replaced by the interpolated topography values in the output.
The bin grid that contains a topography map layer. The grid must have a topography data map loaded; the module reads surface elevations from this map and bilinearly interpolates the elevation at each bin point's (X, Y) location. If the bin grid does not contain a topography map, the module will report an error and will not produce output.
A copy of the input bin point vector in which the Z coordinate of every bin point has been replaced by the surface elevation interpolated from the topography map. The output retains the same bin positions (X, Y) as the input; only the elevation values are updated. Connect this output to subsequent modules that require topography-stamped bin geometry, such as statics computation or geometry QC modules.
Three built-in visualization views are available after execution:
CrookedLine — a plan-view (X/Y) map showing the horizontal trace of the crooked seismic line. Use this panel to confirm that the bin geometry follows the expected surface path.
Input Topography — a profile view showing the elevation values carried by the input bin points before the update. Use this panel to verify the original elevation data or to compare against the updated result.
Output Topography — a profile view showing the updated elevation values along the line after interpolation from the topography map. Compare this with the Input Topography panel to confirm that the elevations have been updated correctly from the grid.
This module has no configurable parameters. The topography update is performed automatically based on the connected input data. No user interaction is required beyond connecting the InputBinVector and GBinGridItem data items.
