Several samples visually interpreted from the very high-resolution images from Google Earth for rice mapping research in China

A dataset for several samples visually interpreted from the very high-resolution images from Google Earth for rice mapping research in China.The file format is GeoParquet, and the geometries are Polygons, which contain three fields: covertype, region, and year, which represent the covertype code, the name of the provincial administrative region, and the year of the polygon, respectively. The meanings of the covertype codes are as follows:0: non-cropland (natural vegetation, built-up areas, water bodies...)1: single-season rice (certain)2: double-season rice (certain)3: rice (uncertain whether it is single- or double-season rice)4: other crops (maize, soybean, peanut...)5: non-rice (maize, soybean, peanut, natural vegetation, built-up areas, water bodies...)

本数据集面向中国水稻制图研究，包含从谷歌地球（Google Earth）超高分辨率影像中目视解译得到的若干样本。数据集采用GeoParquet文件格式，几何类型为多边形（Polygons），内置三个字段：地物类型编码（covertype）、省级行政区名称（region）以及多边形对应年份（year），分别代表地物类型代码、省级行政区划名称与该多边形对应的解译年份。
地物类型编码的具体含义如下：
0：非耕地（含自然植被、建成区、水体等）
1：单季稻（类型确定）
2：双季稻（类型确定）
3：水稻（单/双季种植类型不确定）
4：其他作物（含玉米、大豆、花生等）
5：非水稻地物（含玉米、大豆、花生、自然植被、建成区、水体等）
