h2. Name

*gsu* — Grid surface points

h2. Syntax
{panel:|borderStyle=solid|borderWidth=1|bgColor=#FFFFAA}

*gsu* \[*inc*] | \[_nx ny_] \[*trend* _trendgrid_] \[*ref* _referencegrid_] 

{panel}

h2. Description

General gridding command from input points using a minimum curvature algorithm into a grid surface. The gridding can also try to follow a trend grid that is placed in workspace. The algorithm has good extrapolation qualities as shown in the example. 

h2. Arguments

No arguments. 
{indent}The grid will have the same number of rows and columns as the last grid that set the @nrow @ncol variables.{indent} 
*inc* _xinc yinc_ 
{indent}Create grid model grid with increments _xinc_ and _yinc_ .{indent} 
_nx ny_ 
{indent}Create a grid with nx times ny grid cells.{indent} 
*trend* _trendgrid_ 
{indent}Apply a trend grid in workspace _trendgrid_ for the gridding process.{indent} 
*ref* _referencegrid_ 
{indent}Apply a reference grid in workspace _referencegrid_ for grid layout. Dimension of the grid is taken from the _referencegrid_.{indent}
