SMS:Grid Frame Properties

The Grid Frame Properties dialog is accessed when the Create 1D Grid Frame tool or the Create 2D Grid Frame tool is used. It can also be accessed after a grid frame has been created by using Select 1D Grid Frame tool or the Select 2D Grid Frame tool then right-clicking on the grid and selecting the Properties command from the right-click menu.

The Grid Frame Properties dialog allows the user to specify the attributes applied to the grid frame when performing a Map → 2D Grid operation. These properties are as follows:

• Origin
• Orientation
• Directional properties (u and v direction)
  • Define cell sizes – specified uniform cell sizes
    • Cell size – the cell size in the specified direction
    • Number of cells – number of cells in the specified direction
  • Use refine points – refine points will be used to generate the grid
    • Maximum cell size – the max size the should exists when growing
    • Maximum bias – the max growth ratio to be used when growing
    • Use inner growth – specifies whether the cell sizes should grow between two refine points
  • Grid size – the grid dimension in the specified direction

When the user specifies "Define cell sizes", there are a few options available. These options are:

1. Specify cell size – specify the cell size and the number of cells will be computed.
2. Specify number of cells – specify the number of cells and the cell size will be computed.

If the grid is to have square cells, the v direction cell size will always be linked to the u direction cell size.

The Grid Frame Properties dialog varies depending on the active coverage.
