Google Earth Engine——USGS/LIMA/MOSAIC南极洲大地卫星图像镶嵌（LIMA）是一个无缝的、几乎无云的数据，由经过处理的大地卫星7 ETM+场景创建。

Landsat Image Mosaic of Antarctica (LIMA) 16-Bit Pan-Sharpened Mosaic

The Landsat Image Mosaic of Antarctica (LIMA) is a seamless and virtually cloudless mosaic created from processed Landsat 7 ETM+ scenes.

This LIMA dataset is the 16-bit Intermediate LIMA. The mosaic consists of pan-sharpened normalized surface reflectance scenes (Landsat ETM+ bands 1, 2, 3, and 4). The mosaic was constructed by ordering cloud free images on top and trimming image boundaries when tile discontinuities occurred.

Users can find the mosaic tile footprints available at: USGS/LIMA/MOSAIC_TILE_FOOTPRINTS

南极洲大地卫星图像镶嵌（LIMA）是一个无缝的、几乎无云的数据，由经过处理的大地卫星7 ETM+场景创建。

这个LIMA数据集是16位的中级LIMA。马赛克由泛锐化的归一化表面反射率场景（Landsat ETM+波段1、2、3和4）组成。镶嵌是通过将无云图像排序在上面，并在出现瓦片不连续时修剪图像边界来构建的。
