| | 22 | |
| | 23 | * Hardware options. Once set these should never change (unless the system is modified etc) Should be supplied when the system is delivered. Can view/set these from File > Processing Options. |
| | 24 | * Output file options. Set the projection details, LAS file format, and whether want GeoTIFF or ASCII output awswell. Also contains options for debugging. |
| | 25 | |
| | 26 | * Input options |
| | 27 | * Atmospheric Correction. Need values of the altitude, temperature and pressure for a low altitude and high altitude. With these values a correction gradient will be produced. |
| | 28 | * Range Correction. A time-distance delay in metres of the ALS system, in the measurement of range data. (This is complicated...see user manual for details) |
| | 29 | * Scanner Correction. These do not need to be changed after the calibration/boresighting of the system. |
| | 30 | * POS errors. Angular difference between the IMU and the ALS optics reference frames. Needs to be known accurately. |
| | 31 | * Elevation offset. This is usually non zero. It is identified using the TScan Control Report (eh?). The LIDAR is then reprocessed using the opposite of the DZ offset. |
| | 32 | * Itenisty. Use the Raw intensity. |
