Property search engine Ononemap has added the locations of mobile telecommunications aerials to its maps.

The site displays available properties, to buy or rent, graphically, rather than as a list. It can be set to show locations of schools and supermarkets as well as properties that have already been sold, along with their prices.

Now users can also see where the nearest mobile phone masts are to houses under consideration. The site also shows other masts used by railway companies and the emergency services.

The company said it will be adding more data to its maps in 2007.
