俄罗斯1:250万冻土类型数据集是对1991－1996年俄罗斯出版1：250的《Geocryological Map of Russia and Neighbouring Republics》系列图进行数字化，该图采用俄语标注，共16幅。1998年，Zaitsev等将其翻译为英文。本次数字化，将选择其中的7个主题进行数字化，分别为：1）Distribution of frozen and unfrozen ground，2）Mean annual temperature of frozen and unfrozen ground at the depth of zero annual amplitude，3）Thick of permafrost，4）Depth from the surface and thickness of relict permafrost, 5）Distribution of permafrost containing cryopegs, 6）Thickness of permafrost containing cryopegs, 7）Distribution of permafrost with depth。

The maps are annotated in Russian and consist of a total of 16 images. In 1998, Zaitsev et al. translated it into English. For this digitization, 7 themes will be selected for digitization, namely: 1) Distribution of frozen and unfrozen ground，2）Mean annual temperature of frozen and unfrozen ground at the depth of zero annual amplitude，3）Thick of permafrost，4）Depth from the surface and thickness of relict permafrost, 5）Distribution of permafrost containing cryopegs, 6）Thickness of permafrost containing cryopegs, 7）Distribution of permafrost with depth。
