[DataPrep] csv file with train/val/test files

[jejjohnson]

We need a csv file with all of the filenames for the images and ground truths. A simple glob will be sufficient.

---

Format

Some key columns for easy querying.

• filename, e.g. filename
• filepath, e.g. path/to/file
• bucket, e.g. ml4floods
• split - e.g., train, test, val

---

TiffImages

These are the original tiff images that were used before the train-test-split.

Location: Should be in the ml4floods_data_lake directory. The csv file should be at the top of the directory where the tiffimages are located.

• [x] CSV File

Train/Test/Val

This will be the train/test/val split data.

Location: Should be in the ml4floods_data_lake directory. The csv file should be at the top of the directory where the train/val/split is located.
