Table 2 Potential of the method per type of image resolution

From: A new tool for the remote sensing of groundwater tables: satellite images of pastoral wells

  Resolution Radiant Tracks Ring of Organic Matter Cattle Tracks
Landsat 7 and 8 30 m Often discernible on busy wells Discernible, but not measurable Never visible
SPOT 6 and 7 2 m Always discernible Often clearly visible and measurable Often visible and sometimes measurable
Worldview 3 and 4 0.3 m Always discernible Always clearly visible and measurable Always visible and measurable; cattle are often even countable
