# ELDOR Data

- Public dataset name: `ELDOR`
- Local dataset root: `GoldMDD/data`
- Output folders: `train/image`, `train/label`, `val/image`, `val/label`, `test/image`, `test/label` (copied from `GoldMining/Data/Orthomosaic` and `GoldMining/Data/Label`).
- Source folders: `Drone_Orthomosaic_V1/Orthomosaic_org` and `Drone_Orthomosaic_V1/Just_labels`
- Matching rule: label to orthomosaic by filename mapping, then crop/reproject label to orthomosaic grid.
- Canonical labels: 14 semantic classes (`1..14`) plus `0=Background` after class merging in ELDOR.
- Split rule in this dataset: train/val/test assignment is listed in the `Split` column of the spatial metadata table.

## Generation workflow

- Source orthomosaic/label alignment and original canonical labels come from `GoldMining/Data`.
- ELDOR labels are remapped from the original 19-class canonical IDs into a 14-class merged scheme (stored only under `GoldMDD/data/*/label`).
- Merge rules:
  - `Heavy machinery` = original IDs 5 (Front loader), 8 (Excavator), 9 (Heavy machinery), 19 (Dump truck)
  - `Vehicles` = original IDs 17 (Vehicles), 18 (Small vehicles)
  - `Building` = original IDs 1 (Urban area), 4 (Mining camp)
- Heatmap output: `GoldMDD/site_class_pixel_counts_heatmap_merged.png`
- Heatmap CSV: `GoldMDD/site_class_pixel_counts_merged.csv`
- Train/val/test distribution plot: `GoldMDD/train_val_test_class_distribution_merged.png`
- Train/val/test distribution CSV: `GoldMDD/train_val_test_class_distribution_merged.csv`

## Cropped patch dataset (`data-cropped`)

- Output root: `GoldMDD/data-cropped`
- Patch size: `512x512`
- Stride: `256`
- Filtering rule: drop a patch if background pixels in the merged label (`label==0`) are `>80%`.
- Windowing rule: full windows only (no padding).
- Patch naming: matching basenames per pair, e.g. image `AcumulacionAaron2B_2_3.jpg` and label `AcumulacionAaron2B_2_3.png` (1-based row/col indices).
- Storage format: image patches = JPEG, label patches = PNG (lossless class IDs).
- Folder structure: `train/image`, `train/label`, `val/image`, `val/label`, `test/image`, `test/label`.
