What is pan-sharpening and how can I create a pan-sharpened image?


Pan-sharpening is a technique that merges high-resolution panchromatic data with medium-resolution multispectral data to create a multispectral image with higher-resolution features.

The Panchromatic Image Sharpening of Landsat 7 ETM+ page provides details on pan-sharpening Landsat 7 data. The process will be similar for Landsat 8 data (band file names will differ).


Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
