Satellite dataset I (global cities)
收藏资源简介:
其中之一是从世界各地的城市和各种遥感资源中收集的,包括QuickBird,Worldview系列,IKONOS,ZY-3等。我们手动划定了所有的建筑。它包含204图像 (512 × 512块,分辨率从0.3 m到2.5 m)。除了卫星传感器的差异外,大气条件,全色和多光谱融合算法,大气和辐射校正以及季节的变化使样品适合于测试建筑物提取算法的鲁棒性,但具有挑战性。
One such dataset was collected from cities across the globe and various remote sensing resources, including QuickBird, Worldview series, IKONOS, ZY-3, etc. We manually annotated all building footprints in the images. It contains 204 images of 512 × 512 pixels, with spatial resolutions ranging from 0.3 m to 2.5 m. Besides the disparities among satellite sensors, variations in atmospheric conditions, panchromatic and multispectral fusion algorithms, atmospheric and radiometric corrections, and seasonal changes render this dataset suitable yet challenging for evaluating the robustness of building extraction algorithms.
