-# EnIGMA
-
-EnIGMA is a drone orthomosaic semantic-segmentation dataset for mining-site analysis in Madre de Dios, Peru.
-
-- 12 sites
-- Site-level split: train / val / test
-- Image-label pairs are aligned and share the same spatial footprint per site
-
-## Split definition
-
-- **train (4 sites):** `AcumulacionAaron2B`, `Kotsimba`, `Los5Rebeldes`, `PlayaMirador1`
-- **val (3 sites):** `Clavelito`, `Nayda`, `PlayaMirador2`
-- **test (5 sites):** `Anel`, `ElEngano`, `Linda`, `Paolita`, `SantaInesDosMil`
-
-`PlayaMirador` is split into two non-overlapping halves:
-- `PlayaMirador1`: bottom half (train)
-- `PlayaMirador2`: top half (val)
-
-## Class definition (14 classes + background)
-
-Background is encoded as `0`. Class IDs `1-14` are foreground classes.

+# GoldMDD Data
+
+- Output 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 GoldMDD.
+- 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`.
+- GoldMDD 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`.
