| | 6 | 2 points with an up_catchment_area >40000 and a st_cs_largeurlameeau very small (<15).[[BR]] |
| | 7 | View with the up_catchment area >40000 - they correspond to the riversegement with the maximal higth, so the problems don't come from the calculation of the up_catchment_area, but when we join the CCM layer and the BDMAP points.[[BR]] |

| | 13 | Point 06840051[[BR]] |
| | 14 | The join is good between the CCM and BDMAP, maybe it's the largeurlameau which is wrong.[[BR]] |
