North Temperate Lakes LTER Yahara Lakes District Land Use - Land Cover 1930s

Land use/land cover was interpreted from historical aerial photographs for selected watersheds in Dane County, Wisconsin. Photography from the 1930s, 1960s, and 1990s were interpreted, resulting in land use/land cover data for three time periods.本数据集针对美国威斯康星州戴恩县的选定流域，基于历史航空摄影影像完成了土地利用/土地覆被（land use/land cover）的解译工作。本次解译采用了1930年代、1960年代及1990年代的航空摄影资料，最终得到了对应三个时间阶段的土地利用/土地覆被数据。
