| # Dataset Viewer | |
| This app provides a way of exploring samples present in the MajorTOM-Core dataset. | |
| It contains nearly every piece of Earth captured by ESA Sentinel-2 satellite as well as a large fraction of paired Sentinel-1 data from a similar time period. | |
| ### Instructions | |
| To find a sample, navigate on the map to a place of interest. Click `Find Sample` to find a dataset sample that contains the central pixel of your current view. | |
