EDIT: I have posted this question to the history.SE after a discussion on that site's meta.
Are there any sources of historical land use/land cover data for the United Kingdom? I'm specifically interested in datasets that, for each point/area in the UK (ideally, at as a high a resolution as possible), list whether the land was forest, urban, agricultural/cultivated, etc. for the time period 1800-1900.
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/
