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.
