Vector Grid Wizard

Creates a polyline or polygon vector grid using user defined extents and cell size.

Inputs:

• Initial extent of the grid - the grid will be generated using the coordinate system and units of:
  • the current view
  • a layer from the current view
• Output spatial reference - the grid will be stored in the spatial reference of
  • the current view
  • a layer from the current view
• Grid type
  • Polyline
  • Polygon
• Cell size in  X and Y directions

Outputs:

• New  Polyline or Polygon feature class

Notes:

• The initial extents of the grid are defined by the extents of the selected layer or current extents of the data frame. The extents can be changed manually during the dialog.
• The cell size will be in the units of the input layer or data frame. If the input is Unprojected (Geographic "Projection") there is an oprion to input values in Degrees - Minutes - Seconds
• If the input is Unprojected only values between X = -180 To 180 and Y = -90 To 90 will be accepted
• If the Input is Projected and the Output is in different projection, the user should make sure that the Grid extents are valid
• In order to avoid incorrect inputs, the size of the grid is limited to 4,000,000 cells (2000 by 2000)
• A ET_Index field will be added to the attribute table. The values will indicate:
  • Polygon grid - the index of each Grid cell. The cell in the bottom left corner of the Grid will have an index of "0-0"
  • Polyline grid - the X (Y) for each polyline in the input units.
