Introduction #

The Semantic Segmentation Satellite Imagery dataset was taken from the project for the Kaggle Competition organised by CentraleSupelec Deep Learning course. The training dataset consisted of 261 images taken by a small UAV in the area of Houston, Texas to assess the damages after Hurricane Harvey. Each pixel was segmented into one of 25 classes such as property roof, trees / shrubs, road / highway, swimming pool, vehicle, flooded, etc.

Summary #

Semantic Segmentation with PyTorch Satellite Imagery is a dataset for a semantic segmentation task. It is used in the geospatial domain. Possible applications of the dataset could be in the search and rescue (SAR) and environmental industries.

The dataset consists of 261 images with 2478 labeled objects belonging to 25 different classes including background, grass, trees / shrubs, and other: property roof, vehicle, chimney, secondary structure, swimming pool, power lines & cables, window, road / highway, flooded, dense vegetation / forest, street light, water body, garbage bins, trampoline, satellite antenna, parking area - commercial, solar panels, under construction / in progress status, boat, sports complex / arena, industrial site, and water tank / oil tank.

Images in the Semantic Segmentation Satellite Imagery dataset have pixel-level semantic segmentation annotations. All images are labeled (i.e. with annotations). There is 1 split in the dataset: train (261 images). The dataset was released in 2022.

Here are the visualized examples for the classes:

Co-occurrence matrix #

Co-occurrence matrix is an extremely valuable tool that shows you the images for every pair of classes: how many images have objects of both classes at the same time. If you click any cell, you will see those images. We added the tooltip with an explanation for every cell for your convenience, just hover the mouse over a cell to preview the description.

Images #

Explore every single image in the dataset with respect to the number of annotations of each class it has. Click a row to preview selected image. Sort by any column to find anomalies and edge cases. Use horizontal scroll if the table has many columns for a large number of classes in the dataset.

Object distribution #

Interactive heatmap chart for every class with object distribution shows how many images are in the dataset with a certain number of objects of a specific class. Users can click cell and see the list of all corresponding images.

Class sizes #

The table below gives various size properties of objects for every class. Click a row to see the image with annotations of the selected class. Sort columns to find classes with the smallest or largest objects or understand the size differences between classes.
