AI-generated Key Takeaways
-
The GLS2005 dataset contains 9500 orthorectified leaf-on medium-resolution satellite images of Earth's land masses collected between 2004 and 2007, primarily using Landsat 5 and 7 data.
-
This dataset specifically includes six common bands (10, 20, 30, 40, 50, 70) from the Landsat 5 TM and Landsat 7 ETM+ sensors, with a pixel size of 30 meters.
-
Landsat datasets are in the public domain and can be used without copyright restriction, but acknowledgement of the U.S. Geological Survey as the source is encouraged.
-
The dataset is available through Google Earth Engine, a platform for geospatial data analysis and visualization, and is free for research, education, and nonprofit use.

Description
The GLS2005 data set is a collection of 9500 orthorectified leaf-on medium-resolution satellite images collected between 2004 and 2007 and covering the Earth's land masses. GLS2005 uses mainly Landsat 5 and gap-filled Landsat 7 data with EO-1 ALI and Terra ASTER data filling in any data holes.
This dataset contains images from just the L5 TM and L7 ETM+ sensors, and only the 6 bands that those two sensors have in common: 10, 20, 30, 40, 50, and 70.
