AI-generated Key Takeaways
-
The GLS2005 dataset provides orthorectified, medium-resolution satellite imagery of Earth's land masses collected between 2004 and 2007.
-
This specific collection focuses on Landsat 7 ETM+ sensor data, a subset of the broader GLS2005 dataset.
-
Images include spectral bands ranging from blue to shortwave infrared, with a pixel size of 30 meters for most bands and 60 meters for thermal infrared.
-
Landsat data is public domain and can be freely used, but proper attribution to the USGS is required.
-
The dataset is accessible through Google Earth Engine for analysis and visualization.

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 collection contains just the subset of the GLS2005 images from the L7 ETM+ sensor.
