Google Earth Engine—ETOPO1是一个1弧分的地球表面全球浮雕模型，整合了陆地地形和海洋测深。它是由许多全球和区域数据集建立的。它包含两个高程带：冰面和基岩。

ETOPO1 is a 1 arc-minute global relief model of Earth's surface that integrates land topography and ocean bathymetry. It was built from numerous global and regional data sets. It contains two elevation bands: ice_surface and bedrock.
