I provide some free online mapping services which you are welcome to use: Postcode-decode, which provides mapping and information on postcodes in Great Britain; and How far can you see at sea, which tells you how far you can see at sea at different heights above sea-level.
I also draw on my experience in producing online mapping in my data journalism training.
