Create Seam Surface (Reverse Distance)

Create Seam Surface (Inverse Distance) operation is used to create a surface with inverse distance method considering the lithology and seam levels. 

2D Grid

Use The Box Enclosing as Border:It is selected in order to determine the outer border of the surface to be created as a box according to the outermost drill/lithology/seam. 

X Range: Sampling range on X direction. 

Y Range:Sampling range on Y direction.

Drills from the Project 

Open Filter Window: It is activated when the filter window is opened. In filter windows, criteria can be determined according to drill name, depth, feature values, lithology and vein determinations.

Group Filter: Filter can be applied according to drilling groups created in Drills tab under Catalog. Surface is then created taking into account the drills in selected group filter.
Drilling Points 

Coordinate Filter: It is a position filter belonging to drilling/lithology/seam level (top, middle, bottom, lowermost) upon which the surface shall be created. In order for seam levels to be observable on filter, seam descriptions must be made on drills with Specify Vein Points operation.

Lithology/Vein Filter: It is the filter on which the determination of which lithology or seam unit, upon which the intended surface shall be created, is made.
Output Layer Layer: The name of the layer, on which the created surface will be saved, is determined.
Cut Surface 

Within Border: It is used to create the part inside or outside the selected border of the surface to be created chosen from graphic interface. 

If border selection is carried out while the option is active; surface shall be created inside the border. 

If border selection is carried out while the option is not active; surface shall be created outside the border.

Geostatistical Estimation (Reverse Distance)

Distance: means the radius of the sphere from which the samples shall be chosen.  

Is it ellipse/ellipsoid?: 

Maximum Number of Adjacents: 

Alpha: Alpha value can practically be taken as 1 or 2.  The more the value, the closer it gets to nearest adjacent method. 

Max: Maximum sample number to be used in the estimation of the point. 


Side Slope (Degree):
