MapsLong and MapsLat
These two keywords are required to set up a Maps view. They select the longitude (MapsLong) and latitude (MapsLat) of the markers displayed on the map.
This keyword allows you to choose what column you would like to display as a tooltip. You can display a simple column to display a value but it can be especially interesting to display a template column.
Setting up a tooltip template is the same as any other HTML template. You can also follow this tutorial for a step by step guide. You will simply need to add "MapsTootip" in the second row of the template column in your data sheet.
