Cropland dataset for Canada for AD1000-2015

By quoting and revising historical documents, we estimated Canada's population and per capita cropland area for AD 1000–2015. Then, we multiplied them and combined the census data to get the cropland area of Canada for AD 1000–2015. Subsequently, after determining the maximum extent of cropland in different historical periods and using a sophisticated land suitability map for cultivation, we constructed the cropland area allocation model and mapped the spatial pattern of cropland in Canada with a resolution of 1 km for the past millennium (1000, 1500, 1600, 1700, 1800, 1850, 1870, 1900, 1920, 1940, 1960, 1980, 2000, and 2015).
