Hint

The menu directly beside the map shows the available data that could be layered on the map.
Once a dataset is selcted, it is shown on the map with different icons.
Multiple datasets can be layered over each other at one time but due to heavy computational requirement, if your device does not have a lot of computational power, it is adviceable to be concious of the number of datasets layered simultaneously as your broswer could freeze or potentially crash due to heavy workloads.
