A grid is a network of evenly spaced horizontal and vertical lines used to identify locations on a map. You can also use grids to display locations using projected coordinates on the map.
Graticules are lines showing parallels of latitude and meridians of longitude for the earth.
Graticules can be used to show location in geographic coordinates (degrees of latitude and longitude). Below is a map of Europe where graticules are visible for every 5 degrees latitude and 10 degrees longitude:
Overlay multiple grids
You can combine grids and graticules to display multiple coordinate systems on the same map. For example, you might want to use a universal transverse Mercator (UTM) grid in one color and show graticules in another. Below are steps to add multiple grids.
- On the Insert tab, in the Map Frames group, click Grid and then select a grid or graticule from the gallery.
- To further modify the grid or graticule, in the Contents pane, expand the map frame, right-click the Grid, and click Properties.
- Repeat these steps to add and modify additional grids and graticules.
