+# MM-LUCAS
+
+MM-LUCAS is a multimodal benchmark built on top of the EU's LUCAS (Land Use/Cover Area frame Survey) land-cover survey, pairing 1,784 landscape photos (1600×1200, taken across 27 EU countries) with microdata the survey already recorded: GPS location, country, capture date, land-cover and land-use taxonomy codes, and quality/aesthetic ratings. It's the dataset behind AgriBench, the first benchmark built to evaluate multimodal LLMs on agriculture tasks.

+
+## About the paper
+
+AgriBench turns the LUCAS microdata into four VQA tasks over the same 1,784 images:
+
+- **Land cover** — 4-option multiple choice over LUCAS's land-cover classes (e.g. "Shrubland with sparse tree cover", "Broadleaved woodland").
+- **Land use** — 4-option multiple choice over LUCAS's socio-economic land-use classes (e.g. "Kitchen garden", "Semi-natural and natural areas not in use").
+- **Aesthetic score** — a 5-point qualitative rating of the photo itself (Bad / Poor / Fair / Good / Excellent).
+- **Quality score** — a 5-point qualitative rating of image/capture quality (Bad / Poor / Fair / Good / Excellent).

+## Dataset Size
+
+| Config | Rows | Unique Images | Image Data |
+|---|---|---|---|
+| train | 7,136 | 1,784 | 0.92GB (1 shard) |
+
+All four tasks share the exact same 1,784 images, so every image contributes 4 rows (one per task) rather than being split into separate configs.
+
+## Task Breakdown
+
+| Task | Mechanism | Rows |
+|---|---|---|
+| aesthetics_score | open-ended rating (Bad/Poor/Fair/Good/Excellent) | 1,784 |
+| quality_score | open-ended rating (Bad/Poor/Fair/Good/Excellent) | 1,784 |
+| land_cover | multiple-choice (4 options) | 1,784 |
+| land_use | multiple-choice (4 options) | 1,784 |
+
+For the multiple-choice tasks, the assistant turn combines the answer key with its option text, e.g. `"D. Broadleaved woodland"`, rather than the bare letter the source JSON gives. For the rating tasks, the source answer is already a plain-text label (e.g. `"Poor"`), used as-is.
+
+## Layout
+
+```
+train-0000-of-0001.parquet          # 7,136 rows
+images/
+  image-shared-000-of-001.zip       # image shard (ZIP_STORED, uncompressed)
+  path_to_shard.parquet             # maps image SHA256 hash -> shard_file
+```
+
+Images are content-addressed by SHA256 hash and stored uncompressed in zip shards for random access via `zipfile`, capped at 5GB per shard (this dataset only needed one).
+
+## Schema
+
+| Column | Type | Description |
+|---|---|---|
+| `images` | `list<struct<bytes, path>>` | `bytes` is `null`; `path` is the SHA256 hash, looked up in `images/path_to_shard.parquet` |
+| `id` | `string` | `mmlucas_<task>_<n>` |
+| `messages` | chat-style list | user turn: image + question (multiple-choice questions include lettered options inline); assistant turn: the answer, letter-prefixed for multiple-choice questions |
+| `raw_metadata` | JSON string | `task`, `image_path` (original source path), `gps_long`, `gps_lat`, `date`, `nuts0` (EU country code), `Classes` (free-text scene description); plus the task-specific field: `Aesthetic Score`, `Quality Score`, `lc1`/`lc1_label`, or `lu1`/`lu1_label` |
+
+Each row is one (image, task) pair, so every image appears across 4 rows.
+
+## Usage
+
+Recommended, via the AgML python library:
+
+```python
+from agml import loadImageTextToTextDataset
+
+ds = loadImageTextToTextDataset("MM-LUCAS")
+```

+This dataset is indexed and structured on https://project-agml.github.io/ as part of the AgML python library. This dataset was reformatted from its original format to match HuggingFace's Imagefolder standards but requires an external module (agml) that processes and returns a HF Dataset object faster than HF module functions.
