Tool

Tool set

Graticule

GIS

Use the Graticule tool to place a reference grid of real world parallels, meridians, and labels, showing the Earth’s orientation in a given area of the drawing. Unlike a grid that is based on X and Y coordinates, the graticule lines are based on longitude and latitude lines that are inferred from the georeferenced coordinate system.

The Document Georeferencing dialog box opens if the document is not yet georeferenced, to select a coordinate system. See Specifying document georeferencing.

To create a graticule:

Click the tool and insertion mode. Draw Rectangular Area places the graticule grid in a rectangular area, while Draw Polylinear Area draws a polyline for the graticule area. (see Creating polylines).

Click Preferences to open the Graticule Preferences dialog box and specify the tool’s default parameters. The parameters can be edited later from the Object Info palette.

Click to show/hide the parameters.Click to show/hide the parameters.

Parameter

Description

Grid starts at

Specifies the starting location for the grid spacing; the grid lines will intersect at this point

Geodesic coordinates

Specifies the starting location in longitude and latitude coordinates (decimal degree units)

Cartesian coordinates

Specifies the starting location in X and Y distances from the drawing’s internal origin

Grid spacing

 

Geodesic coordinates

Specifies the grid spacing in longitude and latitude coordinates

Cartesian coordinates

Specifies the grid spacing in drawing distances

Major lines at count

Determines the spacing of major lines. For instance, if the value is 10, every tenth line will be major, with nine minor lines between them.

Label

 

Label major lines

Places a label on each major latitude and longitude line

Label grid lines

Places a label on each minor latitude and longitude line

Label style

Specifies whether the degrees on the labels are in decimal or degrees/minutes format

Label precision

Sets the precision for the label display

Attributes

Specifies the pen color and line style for the major lines and grid lines

Click and drag in the drawing to create the rectangular or polyline boundary in the approximate location of the latitude and longitude lines you specified. Make the area larger than the graticule will be, so the graticule will not be cut by the rectangle or polyline. When you complete the shape, a graticule object is created over the specified location.
