Reference maps
A reference map can be used to plot particular points of interest that are not within the FastStats data set. of map would be to overlay retail store information on the top of a shaded map showing distribution of customers.
In our standard holidays dataset this might represent the location of airports, ferry ports or our travel agent locations. In the example screenshot below we’ve taken the location points we used in our earlier expressions to plot all the train stations (green) and tram stop locations (red).
Reference map layers are defined by dragging in a delimited file representing the points of interest. Hovering over those points of interest will give a tooltip with the fields that were present in the data file used for the points (so you can provide extra information about the particular location as a field within the reference file to be shown when you hover over it).
