Are there any sources of historical land use/land cover data for the United Kingdom and Ireland? (Not just Northern Ireland) I'm specifically interested in datasets that, for each point/area in the UK/Ireland (ideally, at the resolution of a parish, since I'm studying historical deforestation at the parish level), list whether the land was forest, urban, agricultural/cultivated, etc. for the time period 1800-1900.
There are modern versions of these data, e.g. the Corine land cover data, which have been addressed in other questions, but nothing historical.
The Ordnance Surveys supposedly include some data like this for the years 1842 onward, but actually looking at the list of years in which each county was mapped shows that the actual data is mostly much later. https://maps.nls.uk/os/6inch-england-and-wales/
See this meta question for a brief discussion about the suitability of this question for history.SE.
