This dataset contains all the Landsat-7 Enhanced Thematic Mapper (ETM+) high-quality ortho-rectified Level 1 (L1T) products (or L1Gt where not enough GCPs are available) over Kiruna, Maspalomas, Matera and Neustrelitz visibility masks. 

The Landsat-7 ETM+ scenes typically cover 185 x 170 km.  
A standard full scene is nominally centred on the intersection between a Path and Row (the actual image centre can vary by up to 100 m).  

Image characteristics: 

• each band requires 50 MB (uncompressed), 
• band 8 requires 200 MB (panchromatic band with resolution of 15 m opposed to 30 m).
