Curate dataset v1.1: remove 294 files without same-block L/R LiDAR pair
Summary
This pull request removes 294 files belonging to 6 trees that cannot be used as complete observations. After this change the dataset contains 107,856 files, which is exactly the version described in our paper.
This pull request also provides the updated leaf area measurements (Irriwell_LA_references.xlsx).
No other data is changed. 9 of the 12 campaign archives are untouched.
Why these files are removed
Every tree in the dataset is scanned from two sides: front (L) and back (R). Each side has 20 RGB images, 20 depth images, one 660 nm LiDAR scan and one 905 nm LiDAR scan, so 42 files per side.
For 6 trees, a matching front/back pair does not exist:
- 5 trees were scanned from one side only. Only the back side (
R) was recorded; the front side (L) is missing from the original data. This was already visible in the overview spreadsheet, where Block 1 lists fewer trees on the front than on the back. - 1 tree has its two sides under different blocks. Tree
MRQ_20210906_112has its front side stored as Block 14 and its back side as Block 12, so the two sides cannot be paired.
A tree without a valid front/back pair cannot be used as an observation, so all files of these trees are removed.

Dataset totals before and after
| Modality | Before | After |
|---|---|---|
| RGB images | 51,500 | 51,360 |
| Depth images | 51,500 | 51,360 |
| 660 nm LiDAR scans | 2,575 | 2,568 |
| 905 nm LiDAR scans | 2,575 | 2,568 |
| Total | 108,150 | 107,856 |
Is anything lost?
No. Hugging Face keeps the full history of the repository. The original version with all 108,150 files stays available and can still be downloaded by selecting the previous version. It will also be tagged v1.0-raw; the new version will be tagged v1.1.
How this was checked
- Each new archive was checked with a ZIP integrity test (no errors).
- The number of files in each new archive was compared with the original: exactly 84, 126 and 84 fewer files, as expected.
- The full dataset was recounted after the change: 107,856 files.
