Grid Geometry for PICScript

Usually you will want to use the geometry of an existing grid for the geometry of your output grid. You can use an available geometry as a starting point and modify it to meet your requirements. See PICScript - Running a Grid Script.

To specify an unique geometry for your grid script output, describe the geometry on the Geometry/Reference tab of the dialog box.

• Your ProductName map is active while you work with PICScript. This means that you can use your cursor to get coordinates from your map or the Distance Ruler to find distances as you lay out the geometry for the new grid.

To define a new geometry your will provide the coordinate location for the origin of the grid (X-Origin, Y-Origin), an angle for the grid (In-line Orientation), the number of grid lines (X-lines and In-lines) and the distance between grid lines (Spacing).

Grid X-lines and In-lines are constructed beginning at the origin.

By default the Grid X direction is East/West and Grid Y direction is North/South with the grid origin in the Southwest. The location of the origin of your output grid will dependent on the in-line orientation you set. View image

The in-line orientation angle is specified in degrees of departure from East/West. The first grid In-line is drawn at the angle you specify and will be long enough to accommodate the required X-lines at the Spacing distance you have chosen. The rest of the grid will be laid out based on this first grid In-line. View images
