I have produced digital mapping for editorial and other purposes, including for a client requiring a map showing its own data and searchable through postcodes. I specialise in choropleth maps of the UK, in particular ones that use areas such as local authority, NHS and other administrative boundaries where I have developed Javascript-based mapping that builds on the Leaflet library, base maps from Carto and open government data.

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.
