National meter-resolution image sample dataset spanning 2013 to 2017 covers six major types of ground features, including soil, water bodies, rocks and minerals, vegetation, snow and ice, and artificial targets. This dataset specifically consists of meter-resolution image samples of artificial targets in China from 2013 to 2016. Each sample is associated with multiple files in formats including TIF, JPG, XML, TXT, and other formats. Specifically, the TIF file contains a 7×7 pixel image centered on the sample point; the JPG file is a thumbnail of the image; the TXT file stores the pixel values of the image at the sample point location; and the XML file serves as the metadata of the sample data. The temporal coverage of the dataset ranges from August 2013 to September 2016.
