| | 46 | == "profile buffer exceeded" - Invalid DEM == |

| | 48 | If, in the azgcorr output, you see output like: |
| | 49 | {{{ |
| | 50 | ** profile buffer exceeded at: 0 points |
| | 51 | |
| | 52 | ** profile buffer exceeded at: 0 points |
| | 53 | |
| | 54 | (repeated many times) |
| | 55 | }}} |
| | 56 | |
| | 57 | This indicates a problem with the DEM. Typically, this would either mean that the DEM wasn't read correctly (check format), doesn't cover the area (check site limits for image and DEM in azgcorr output) or has invalid values in it (e.g. NULL values are a '*' - replace these with 0 or the invalid data value). |
