GEE中的mosaic用法

在GEE中，mosaic函数用于将图像集合中的图像拼接成一个单一的图像。拼接的原则是取覆盖在最上边的图像的像素值作为最终拼接图像的像素值。\[1\]在给定一个图像集合imageCollection后，可以使用imageCollection.mosaic()来执行拼接操作，返回一个拼接后的图像image3。\[1\]

例如，如果有一个图像集合imageCollection包含image1和image2两个图像，那么执行imageCollection.mosaic()后，返回的image3将是覆盖在最上边的图像的像素值。\[1\]

总结来说，mosaic函数用于将图像集合拼接成一个单一的图像，取覆盖在最上边的图像的像素值作为最终拼接图像的像素值。\[1\]
