Topic:
How to interpolate a horizon posted in Basemap?

Description:

Solution:
In Basemap:
1.) Mode > Horizon Interpolation

2.) Set the desired 'Interpolation parameters' by clicking on the 'Interpolation
parameters' button; set the search direction, search tolerance and interpolation
options.

3.) Select the mode of operation:
	a. if using 'Line' mode, click MB1 at the beginning point and the ending 
	   point you want interpolated (3D data will follow the section of the
	   inline or crossline defined by the two MB1 clicks)
	b. if using 'Polygon' mode, define the polygon points on the basemap 
	   with MB1 and stop the polygon with MB3/Break; horizon interpolation 	
	   will automatically begin within the defined polygon
	c. if using 'Paintbrush' mode (3D surveys only), define the size of the
	   paintbrush by clicking the 'Define paintbrush' button, then click 
	   MB1 on the basemap for one corner of the paintbrush, and MB1 for the
	   opposite corner; after the paintbrush is defined, click MB1 on the
	   map to start the interpolation, and drag the paintbrush over the 
	   area you want interpolated
	d. Note: 'Fault trace polygon' mode is used for Mode > Horizon erase,
	   and not Horizon interpolation

3.) The interpolated horizon will not be snapped, so you may want to snap the
horizon.  You can do this in Seis3DV/2DV under Areal > Snap.
