Grids menu contents
The Load/Calculate Grid option is an equation (strictly speaking an 'expression') that defines a new grid to be calculated from a set of existing grids. The grid is loaded and becomes the "buffered" grid.
Select the Triangulate Grid option to use the grid nodes to form a triangulation.
Select the Save Grid option to save the grid to a file. The grid limits and grid size may be modified as part of the saving process.
Select the Define Level Grid option to define a new grid.
Select the Transform Grid option to redefine a grid origin and grid size.
Select the Re-interpolate Grid option to refine a grid by adding more grid nodes.
Select the Import ASCII Grid option to import an ASCII grid file that has been created through another application.
The Close All Grids option closes the open ("buffered") grid.
