黑河地貌数据源自中华人民共和国地貌图集（1:100万）。本数据是基于遥感影像等多源数据集成、更新得到。主要使用和参考的数据包括：1）遥感影像数据：全国1990’s 左右的TM和2000’s 左右的ETM影像；2）历史地貌图：已出版的15幅100万地貌图、两套全国1:400万地貌图、全国各省市区的50万或100万地貌草图；3）基础地理数据：全国1:25万基础地理数据和25万DEM数据；4）地质数据：全国1：50万地质图；5）相关专题图：土地利用图、植被图、土地资源图等。解译方法采用基于ARCGIS的人机交互方式，并按照分层分级的解译顺序进行：即第一层：平原与山地；第二层：基本地貌类型（28种）；第三层：10种成因类型；第四层：次级成因类型；第五层：形态差异划分类型；第六层：次级形态差异划分类型；第七层：坡度、坡向及其组合划分地貌的倾斜程度或坡度；第八层：物质组成或岩性确定的地貌物质类型；第九层：合并1-7层图斑。共包括441种地貌类型及编码。数据字段包括：Fenfu（图幅号)、name(属性）、class(编码）、Sname(行政区划）

This data is based on remote sensing image and other multi-source data integration and update. The main data used and referenced include: 1) remote sensing image data: TM and 2000's around 1990's nationwide ETM image around; 2) historical geomorphic map: 15 published 1 million geomorphic maps, two sets of 1:4 million geomorphic maps in China, 500000 or 1 million geomorphic sketches in all provinces and cities in China; 3) basic geographic data: 1:250000 basic geographic data and 250000 DEM data in China; 4) geological data: 1:500000 geological map in China; 5) relevant thematic maps: land use map, vegetation map and land resource map And so on. The interpretation method adopts the human-computer interaction method based on ArcGIS, and is carried out according to the interpretation sequence of hierarchical classification: the first layer: plain and mountain; the second layer: basic geomorphic types (28); the third layer: 10 genetic types; the fourth layer: secondary genetic types; the fifth layer: morphological difference classification types; the sixth layer: secondary morphological difference classification types; the seventh layer: slope, slope The eighth layer is the type of geomorphic material determined by material composition or lithology; the ninth layer is the combination of 1-7 layers of map spots. There are 441 geomorphic types and codes. Data fields include: fenfu (view frame number), name (attribute), class (code), sname (administrative division)
