Work with a grid

A grid is a network of horizontal and vertical lines used to identify locations on a map. In ArcGIS Pro, there are two categories of grids (graticules and measured grids) that are used to display locations. A graticule displays coordinates in latitude and longitude while a measured grid displays coordinates from a projected coordinate system. In this tutorial, you will add a graticule to a map frame and then modify its components.

Add a map & layout to your project

Before you can add a grid, you will need to add a map and a layout to the project. To do so:

  1. On the Insert tab, in the Project group, click New Map.
  2. On the Insert tab, in the Project group, click New Layout and in the ANSI Landscape section, click Letter 8.5" x 11".
  3. On the Insert tab, in the Project group, click the Map Frame drop-down menu and select the map you just added.
  4. Right-click the map frame on the layout and click Activate.
  5. Navigate to Australia and change the scale of the map to 1:30,000,000.
  6. When you are satisfied with how Australia fits within the map frame, on the Activated Map Frame tab, Close Activation.

Add a grid

  1. On the Insert tab, in the Map Frames group, click the Grid drop-down menu and click the Black Horizontal Label Graticule.
  2. On the Contents pane, right-click the Black Horizontal Label Graticule and click Properties.

    The Format Map Grid pane will open.

Add corner labels

This graticule style includes gridlines, ticks, and labels. The style is not limited to what's included, you can add additional components to your grid. You will start by adding corner labels to provide a clear point of reference for the map.

  1. On the Components tab Components, click the add drop-down menu Add and choose Corner Labels.
  2. To better see the corner labels on the layout, press and hold the C key on your keyboard and zoom into the bottom left-hand corner of the layout.
  3. By default, corner labels are added to all corners. You will change this to show two labels.
  4. On the Format Map Grid pane, under Corner Visibility, click Selected.Then press and hold Ctrl and click 2 and 4 to select both corners.
  5. Uncheck North-South and East-West to turn off those corners.
  6. The remaining corner labels will show labels in the lower-left hand corner and the upper-right hand corner.
  7. While holding the C key on your keyboard, zoom back out to the full extent of the layout.

    The corner labels may appear larger than the labels.

  8. To change the size of the corner labels, under Appearance click the symbol.
  9. Click Properties.
  10. Expand Appearance and change the Size to 8 pt.
  11. Click Apply.
  12. Click the back button to return to the Components tab Components.

Add interior labels

To make the map easier to read, let's add Interior labels to display the latitude and longitude of interior lines on the map.

  1. On the Components tab Components, click the add drop-down menu Add and choose Interior Labels.
  2. Under Positioning, click the 1/3 arrangement button 1/3.

    This adds labels to the grid lines 1/3rd of the way from each map edge.

    The interior labels may appear larger than the labels.

  3. To change the size of the interior labels, under Appearance, click the symbol.
  4. Click Properties.
  5. Expand Appearance and change the Size to 8 pt.
  6. Click Apply.
  7. Click the back button to return to the Components tab Components.

Display labels vertically

For some layouts it can be helpful to orient labels vertically. You will do this for the East and West labels.

  1. In the Components list, click Labels.
  2. Using the C key on your keyboard, zoom in to the West side of the layout.
  3. On the Format Map Grid pane, under Vertical, click East and West.

    Notice how the labels have changed.

Customize intervals

When you insert a measured grid or graticule, Automatically adjust is checked on. This is the default setting so when the map frame is activated and you're zooming in and out the interval changes to avoid cluttering the map. This can be unchecked so that you can further customize the components of the grid.

  1. On the Options tab, uncheck Automatically adjust.
  2. On the Components tab Components, click the Gridlines and while holding down the Ctrl key on your keyboard click the Labels and Interior Labels.
  3. Under Interval, change the Longitude to 10 degrees.

    By default, Sync values is checked on. As changes are made to the Longitude interval the Latitude interval is automatically changed to be the same. In this case, the intervals for both Latitude and Longitude will be changed to 10 degrees. Unchecking this will allow you set different intervals for each axis.

    Example of labels

Save to a style

All the modifications you have made can be saved to a style. Next time you add a graticule to a map you can add this style.

  1. On the Contents pane, right-click the Gray Horizontal Label Graticule and click Save to style.
  2. Provide a Name, Category, Tags, and click Save.

    The style is now added to the grid gallery. To see the style, on the Insert tab, in the Map Frames group, click Grid and the style will appear at the top of the gallery.
