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

AI-generated Key Takeaways

• LIMA is a cloud-free mosaic of Antarctica created from Landsat 7 ETM+ scenes, offering a seamless, high-resolution view of the continent.

• This dataset provides pan-sharpened, normalized surface reflectance in the blue, green, red, and near-infrared wavelengths with a 15-meter resolution.

• The mosaic was created by prioritizing cloud-free images and carefully trimming boundaries to minimize discontinuities.

• LIMA data is public domain and can be used freely, although attribution to the project is appreciated.

• The dataset covers the period from June 30, 1999, to September 4, 2002.

Description

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.
