Oil Spill Tokenized Dataset

This dataset is prepared for an oil spill detection project using satellite imagery and segmentation masks.

Dataset Description

The dataset contains preprocessed satellite images and corresponding oil spill masks.
It is intended for computer vision tasks such as semantic segmentation, oil spill detection, and geospatial AI experiments.

Dataset Structure

The dataset is organized into three splits:

train
validation
test

Each sample may include:

image
mask
filename
tokenized fields, if text/token preparation was applied

Intended Use

This dataset can be used for:

training image segmentation models
testing oil spill detection models
experimenting with satellite image analysis
building AI-based environmental monitoring systems

Project Goal

The main goal of this project is to detect oil spills from satellite imagery and support risk analysis using AI and geospatial data.

Notes

This dataset was prepared as part of an educational AI and geospatial analysis project.
