# Sentinelhub grant: Sponsoring request ID 1c081a - Towards a Smart Eco-epidemiological Model of Dengue in Colombia using Satellite in Collaboration with MIT Critical Data Colombia.
Project supported by ESA Network of Resources Initiative
Project proposal ([READ MORE](https://eo4society.esa.int/wp-content/uploads/2023/06/towards-a-smart-eco-epidemiological-model-of-dengue-in-colombia-using-satellite.pdf))
**Project Organisation**: MIT Critical Data Colombia.
## Model Description
- **Repository:** [Code](https://github.com/sebasmos/satellite.extractor)
- The proposed dataset format is shared in [Metadengue](https://github.com/sebasmos/MetaDengue)
- **ESA project:** Sponsoring request ID 1c081a - Towards a Smart Eco-epidemiological Model of Dengue in Colombia using Satellite in Collaboration with MIT Critical Data Colombia)
- **Point of Contact:** [Sebastian A. Cajas Ordóñez](mailto:sebasmos@mit.edu)
## Summary
Here below find all the dataset's versions and descriptions.
*Baseline method from satellite extractor*: Raw data from Sentinel 2LC1 with recursive artifact removal, clouds removal based on LeastCC and Nearest Interpolation for spatial resolution.
* **SAT1_dataset_5_best_cities**: Top 5 municipalities based on Baseline method from satellite extractor
* **SAT2_dataset_10_best_cities**: Top 10 municipalities based on Baseline method from satellite extractor
*RGB-Version*: [[Link](https://huggingface.co/datasets/MITCriticalData/10_municipalities_RGB)]
* **SAT3_FULL_COLOMBIA**: Top 81 municipalities based on Baseline method from satellite extractor
*DATASET_81_CITIES_v1.0*: [[link](https://huggingface.co/datasets/MITCriticalData/DATASET_81_CITIES_v1.0)]
*DATASET_81_CITIES_v2.0*: [[link](https://huggingface.co/datasets/MITCriticalData/DATASET_81_CITIES_v2.0)]
* **Creating Cloud-Cloudless Paired Dataset**: This dataset, derived from imagery in five Colombian municipalities, consists of 1640 images (820 pairs), where each of the 164 images per municipality is paired with a previously identified optimal cloudless image. The Cloud2CloudlesDataset class organizes these pairs into a new folder (DATASET), with images renamed to indicate ground truth and cloud presence. The class, initialized with source and destination paths, includes tests for image count verification and folder existence confirmation.
* **Dataset on Rio de Janeiro, 2016-2018**: [[link](https://huggingface.co/MITCriticalData/dataset_rio_de_janeiro_2018_2023)] The datasets DATASET_rio_de_janeiro.zip and DATASET_rio_de_janeiro_forward_backwardv2.zip cover central Rio de Janeiro from 2016 to 2023, each containing 416 images per epidemiological week. DATASET_rio_de_janeiro.zip uses single-forward artifact removal, possibly leading to black images, while DATASET_rio_de_janeiro_forward_backwardv2.zip applies forward-backward artifact removal, replacing black images. Visit: https://github.com/sebasmos/satellite.extractor/tree/main/satellite_extractor/PART_1_satellite-augmentation for details.
* **Landsat Colombia 2008-2016**: [[Link](https://huggingface.co/datasets/MITCriticalData/L7_Dataset_2008_2015)]
* **MODIS 2 2008-2016**: [[link](https://huggingface.co/datasets/MITCriticalData/dataset_modis_2_2008_2015)]
* **SAT4_dataset_10_best_cities_augmented_v1**: Augmented data with aligned metadata. Data was extracted using recursive artifact removal, cloud removal based on LeastCC, and Nearest Interpolation for spatial resolution. Implemented [here](https://github.com/sebasmos/satellite.extractor/blob/main/notebooks/satellite_imagery_augmentation.ipynb) and augmentations applied to RGB channels while leaving other satellite channels unchanged:
* **SAT5_dataset_10_best_cities_augmented_v2**: These images are improved to remove near black images method using a recursive [forward-backward artefact removal algorithm with inter-band data augmentation on satellite imagery](https://github.com/sebasmos/satellite.extractor/tree/main/src/PART_2_satellite-augmentation). Augmented data with aligned metadata. Improved version using Albumentation wrapper modules with extra augmented data. Data extracted using recursive artifact removal, cloud removal based on LeastCC, and Nearest Interpolation for spatial resolution. Implemented [Notebook](https://github.com/sebasmos/satellite.extractor/blob/main/notebooks/PART_2_satellite_imagery_augmentation.ipynb) and augmentations applied to RGB channels while leaving other satellite channels unchanged.
## Reading data
The data can be read as (example):
```
from datasets import load_dataset
dataset = load_dataset("MITCriticalData/Unlabeled_top_10_cities_forward_backward_alg")
```
Alternatively, for ```datasets<1.11.0``` the lecture of `.tiff` and `.json` files is not compatible. In such case we recommend to download the data as:
```
wget path_to_data/images.zip && unzip images.zip -d images/
wget path_to_data/annotations.zip && unzip annotations.zip -d annotations/
```
