For this demo I've set up an event in Hyde Park and placed my North East and South West markers in the Site Map.
To continue, we'll head back to General via the tab menu on the left.
For more information on setting up events, please read Creating Events.
Here, we'll set up a basic 4 by 4 grid by entering 4 in the Latitude section and 4 in the Longitude section.
To continue, click 'Update Event' and then view the Site Map through the tab menu on the left.
We can now see that the map has indeed been divided into 4 columns and 4 rows.
We'll now head back to General to make a few adjustments and add some grid labels.
Grid labels are used to quickly identify grid sections by name and make them known to Terminal Users in the field. For this example, I'll be using letters for the Latitude and numbers for the Longitude, but swapping these over or using a different naming convention is entirely up to you so long as it's easy to understand and communicate.
To enter your grid labels, enter the character or characters you wish to use followed by a comma, followed by the next symbol (A,B,C,D) with no spaces. This applies across numbers (7,8,9,10,11,12,13) and words (Apples,Oranges,Pears,Bananas).
You will also want to make sure that the total number of labels across an axis is equal to the amount of segments available across that axis. In order to make the grid sections a little more square, I've adjusted the Longitude sections from 4 to 8, meaning we'll need 4 Latitude labels and 8 Longitude labels.
Therefore in this example Ive added A,B,C,D to the Lat Labels section and 1,2,3,4,5,6,7,8 to the Long Labels section.
To continue, click 'Update Event' and head back to Site Map.
You should now be presented with a labelled grid.
If you need to make any changes, head back to the General tab to make your changes.
