Graticules can be used to show location in geographic coordinates (degrees of latitude and longitude). Graticules from existing ArcMap documents (.mxd) can be imported into ArcGIS Pro and then further modified. The display of the graticule gridlines, ticks, and labels can be rearranged and their appearance altered.
Graticules can be added to map frames and optionally modified to suit your needs.
- On a layout view, select a map frame that references a 2D map.
- On the Insert tab, in the Map Frames group, click Grid and choose a graticule from the gallery.
- To further modify the graticule, in the Contents pane, under the map frame, right-click the grid and click Properties.
Graticules from existing ArcMap documents (.mxd) can be imported to ArcGIS Pro.
- On the Insert tab, in the Project group, click Import Map.
- On the Import dialog, navigate to your ArcMap document (.mxd) and click OK.
The lines, ticks, hatches, and coordinate labels of the graticules are displayed on the imported layout. Graticules and their properties can be accessed in the Contents pane by right-clicking on the name of the graticule underneath Grids.
Modify graticule properties
To access and modify graticule properties, expand the map frame in the Contents pane and right-click the name of the graticule (which is named Grid by default), and click Properties. In the Format Map Grid pane, the following Options for the graticule can be set:
- Name - change the name and how it appears in the Contents pane.
- Visible - toggle the display of the graticule on the layout.
- Interval - automatically adjust the graticule intervals based on scale.
- Origin - specify a custom coordinate origin of longitude & latitude for the graticule.
Gridlines, ticks, and labels can be added or removed on the Components tab . The symbol for each component can be changed under Appearance.
By checking off Automatically adjust on the Options tab , you can change the Interval of latitude and longitude for Gridlines, Ticks, and Labels.
The Appearance of each component can be also be altered by choosing its Length, Offset, and by modifying its Symbol.
Visibility for Ticks, and Labels can be checked on or off for the cardinal directions of the map.
Format labels with tags
Labels are formatted using tags to change their display. You can add multiple labels and format them differently.
- On the Contents pane, if necessary, expand the map frame, right-click the grid and click Properties.
- On the Format Map Grid pane, click the Components tab , and select Labels.
- In the Format text box you can modify your labels by using tags.
The following tags are common to Decimal Degrees, Decimal Minutes, and Degrees Minutes Seconds. To utilize the tags below, follow the example syntax with True or False.
Shows number of decimal places.
Separates between number and direction.
Functions same as zeroPad.
Always shows 3 digits in degree values.
Always shows 2 digits in minute values.
Always shows 2 digits in second values.
True shows N, S, E, or W direction. False will not show direction but will show a negative sign, if applicable. None will neither show direction or a negative sign.
Shows positive sign when showDirections is set to "None" or "False".
Shows degree, minute, or second symbol.
Shows or hides minutes value. If the minutes value is zero, the zero can be added or removed by following the syntax with True or False.
Shows or hides seconds value. If the seconds value is zero, the zero can be added or removed by following the syntax with True or False.
Always shows decimalPlaces numbers to the right of the decimal point.
For a broader review of tags see: Add and modify dynamic text.
The following examples demonstrate how these tags can utilized to modify labels.
Example 1: Degrees with three decimal places and cardinal direction. directionSeparator is any string between the value and the letter denoting cardinal direction. In the example, directionSeparator is a space.
<dyn type="grid" units="dd" decimalPlaces="3" zeroPad="True" showDirections="True" directionSeparator=" "/>.
Example 2: Degrees with three decimal places. showDirections = "False" instructs the labels not to use letters for cardinal direction. A minus sign is used in front of South and West values.
<dyn type="grid" units="dd" decimalPlaces="3" zeroPad="True" showDirections="False"/>.
Example 3: Degrees with three decimal places. showSymbol = "False"/> removes the degree symbol from the label.
<dyn type="grid" units="dd" decimalPlaces="3" zeroPad="True" showDirections="False" showSymbol="False"/>.
Example 4: Degrees with three decimal places. To italicize decimals, a font that supports italic (Arial, for example) is required. Tags that italicize both the degree integer and the decimal value have been added to the example.
<dyn type="grid" units="dd.deg.int" showSymbol="true"/>°<CLR blue="200"><FNT name="Arial" size="5"><ITA><dyn type="grid" vAlign="top" units="dms.min" showZeroMinutes="True"/>'<dyn type="grid" units="dms.sec" showZeroSeconds="True" zeroPad="True" decimalPlaces="0" vAlign="top"/>"</ITA></FNT></CLR>.
Example 5: Degrees, minutes, and 2 decimal places. Degree integer and symbol have been separated into two tags. showZeroMinutes tag is set to True to display minutes. zeroPad is set to True in order to display 2 decimal places.
<dyn type="grid" units="ddm.deg.int"/><dyn type="grid" units="ddm.deg.sym"/><FNT size="4"><dyn type="grid" vAlign="bottom" units="ddm.min" showZeroMinutes="true" zeroPad="true" decimalPlaces="2"/></FNT>.
Format the symbol of each component
The appearance of each grid component can be formatted like any other symbol or text.
On the Contents pane, if necessary, expand the map frame, and select the grid.
The Format contextual tab will appear at the top of the application.
- On the Format tab, in the Current Selection group, select the individual component to modify from the drop-down menu.
Depending on the selection, you may change the symbol or text symbol.
- To make more detailed changes to components of the graticule, on the Contents pane, right-click the grid and select Properties.
The Format Map Grid pane will open.
- On the Format Map Grid pane, on the Components tab , underneath the Appearance, you can further modify the Symbol.
