Dataset Viewer

The dataset viewer is not available because its heuristics could not detect any supported data files. You can try uploading some data files, or configuring the data files location manually.

NEO dataset

Preprocessing and loading scripts for NEO datasets: 1 week and 1 month variants. Go in either 1 week or 1 month directories.

Steps:

Download raw data

Use the ./download_raw_data.py -o raw_data script.

1.1 For weekly data only. Use the preprocess_raw_1week_data.py raw_data -o raw_data_fixed script.
- NDVI is only sampled at 16 days, we make an average of two consecutive samples to create an 8 day average.
- We rename the data from YYYY-MM-DD to YYYY-MM-E (E=1,2,3,4 depending on which week bucket). This is needed because different sensors sample data at different weeks
Convert from PNG to NPY files

Converts from raw PNG to [0:1] normalied, 540x1080 npy files, and adds NaNs to invalid regions in the NEO data.

./convert_png_to_npy.py raw_data -o npy_data [--resolution 540 1080]

If --resolution is not set, it will default to 540 x 1080.

Run the neo_viewer and data analysis notebook
- Set the path to neo_1week/npy_data or neo_1month/npy_data.
Use in ML python scripts via the neo reader. You can also run it with the npy_data.
