🕵️ Introduction

Climate change is upon us.😢 How do we prepare for what is coming? With this challenge, we tackle an interesting idea that helps measure the rate of global warming and deforestation around the world. And that too through satellite images.

In this challenge, we give you satellite images to classify whether the location is of water or not?

With this challenge, we advance the Sustainable Development Goal 14 - Life below water.


Understand with code! Here is getting started code for you.😄

💾 Dataset

The Landsat dataset consists of 400x400 RGB satellite images which have been taken from the Landsat 8 satellite. In each image, there can be water and background. Your classifier should predict each pixel as 0 - background or 1 - water (int). In the train set, you will be given both the rgb images in jpg format and a mask where 0 will denote background, 1 will denote water. In the test set, we will only give you the RGB image.

📁 Files

Following files are available in the resources section:

  • train.zip - (1399 samples) This zip file contains all the rgb (400x400) images that can be used for training

  • train_masks.zip - (1399 samples) This zip file contains all the masks for the rgb images allocated for training.

  • test.zip - (467 samples) This zip contains rgb (400x400) images for which you will need to make the masks and submit a npy file of the same.

🚀 Submission

  • Prepare a npy file which consists of flattened masks where 0 stands for background or 1 stands for water where each elements type is int8. You should iterate through image_0 to image_467 and maintain the order for evaluation to occur properly.

  • Sample submission format available at sample_submission.csv in the resorces section.
