河南省海拔高度分类数据集

河南省海拔高度分级数据集是在河南省省界范围内，选取SRTM DEM 90 m与Google Earth数字高程数据，经过数据拼接、剪裁、转换投影、异常值修复等处理过程，按照<50m、50-100m、100-200m、200-500m、500-1000m、1000-1500m、1500-2000m和>2000m将高程数据分为8类，并对每个类型进行了面积统计。结果表明，河南省平原（海拔高度200m以下）面积占67.63%，丘陵（海拔高度为200-500m）面积占16.89%，山地（海拔高度500m以上）面积约占15.48%。本数据集以.tif和.xlsx格式存储，压缩后数据量为1.41MB。本数据集可以作为支持河南省资源、环境、生态领域研究的基础数据。

The Henan Province Elevation Classification Dataset is developed within the administrative boundary of Henan Province. SRTM DEM 90 m and Google Earth digital elevation data were selected as source data, and processed through procedures including data mosaic, clipping, projection transformation, outlier repair and other steps. The elevation data were classified into 8 categories according to elevation thresholds: <50 m, 50–100 m, 100–200 m, 200–500 m, 500–1000 m, 1000–1500 m, 1500–2000 m, and >2000 m, and area statistics were conducted for each category. The results show that the plain area (with elevation below 200 m) of Henan Province accounts for 67.63%, the hilly area (with elevation of 200–500 m) accounts for 16.89%, and the mountainous area (with elevation above 500 m) accounts for approximately 15.48%. This dataset is stored in .tif and .xlsx formats, with a compressed size of 1.41 MB. It can serve as basic supporting data for research in the fields of resources, environment and ecology in Henan Province.
