2D Grids may be converted to other types of data used in GMS, such as a TIN, 2D mesh, or 2D scatter points. 2D Grids can be converted by using the following commands in the Grid menu:

Grid → 2D Scatter Points

The Grid → 2D Scatter Points command in the Grid menu is used to create a new scatter point set using the nodes or cells of a 2D grid. A copy is made of each of the datasets associated with the grid and the datasets are associated with the new scatter point set.

Grid → TIN

A new TIN can be created from a 2D grid by selecting the Grid → TIN command from the Grid menu. Two triangles are created from each cell in the grid.

Grid → 2D Mesh

A new 2D finite element mesh can be created from a 2D grid by selecting the Grid → 2D Mesh command from the Grid menu. A four node quadrilateral element is created from each cell in the grid.

Grid → Ugrid

A new Ugrid can be created from a 2D grid by selecting the Grid → UGrid command from the Grid menu. The new Ugrid will use the dimension of the 2D Grid.

Contours → Arcs

Creates a new feature coverage containing arcs derived from the linear contours on the 2D grid. The command only works if linear contours are being displayed.
