Data products are processed at various levels ranging from Level 0 to Level 4. Level 0 products are raw data at full instrument resolution. At higher levels, the data are converted into more useful parameters and formats. These are derived from NASA and NEON
| Level | Description | |
|---|---|---|
| 0 | Reconstructed, unprocessed, full resolution instrument data; artifacts and duplicates removed. | |
| 1a | Level 0 plus time-referenced and annotated with calibration coefficients and georeferencing parameters (level 0 is fully recoverable from level 1a data). | |
| 1b | Level 1a processed to sensor units (level 0 not recoverable) | |
| 2 | Derived variables (e. g., NDVI, height, fluorescence) at the level 1 resolution. | |
| 3 | Level 2 mapped to uniform grid, missing points gap filled; overlapping images combined | |
| 4 | 'phenotypes' derived variables associated with a particular plant or genotype rather than a spatial location |
