中国31省市彩钢板建筑0.3米分辨率遥感数据集（2021-2025年）

中国31省市彩钢板建筑0.3米分辨率遥感数据集E-GCS（Enhanced Generic Color Steel）包括彩钢板建筑遥感影像数据和像素级精细标注标签数据两类核心数据。遥感影像数据为Google Earth平台获取的高分辨率影像，包含蓝、红、白三类彩钢板建筑的光谱、纹理、空间结构及周边环境交互特征等信息；标签数据基于Label Me标注生成，包含彩钢板建筑的像素级边界轮廓、颜色类别（蓝、红、白）、空间分布位置等语义分割标注信息，所有数据按省级行政区划归档整理。

The 0.3-meter resolution remote sensing dataset E-GCS (Enhanced Generic Color Steel) focuses on color steel buildings across 31 provincial-level administrative regions in China, comprising two core data types: remote sensing imagery data of color steel buildings and pixel-level finely annotated label data. The remote sensing imagery data, sourced from Google Earth, are high-resolution images that capture spectral, texture, spatial structure, and surrounding environmental interaction features of three categories of color steel buildings: blue, red, and white. The label data, generated via Label Me annotation, include semantic segmentation annotation details such as pixel-level boundary contours, color categories (blue, red, and white), and spatial distribution locations of color steel buildings. All datasets are archived and organized according to provincial administrative divisions.
