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
| Â | 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 |
