Map of islands and shallow water areas in the Spermonde Archipelago (Indonesia)

This repository contains data and code used to make a map of islands and shallow water areas for the Spermonde Archipelago, Indonesia. The map was obtained using a two-stepped classification approach, described below, and simple statistics and graphs were then calculated in python. This work was inspired by the "Geoscientific Project" of Mr. Dennis Flenner, University of Bremen, who classified the same area with SENTINEL2 and QGIS tools. This work was supported through grant SEASCHANGE (RO-5245/1-1) from the Deutsche Forschungsgemeinschaft (DFG) as part of the Special Priority Program (SPP)-1889 “Regional Sea Level Change and Society”.

MagicBathyNet: A Multimodal Remote Sensing Dataset for Bathymetry Prediction and Pixel-based Classification in Shallow Waters

The dataset MagicBathyNet is a benchmark dataset made up of image patches of Sentinel-2, SPOT-6 and aerial imagery, bathymetry in raster format and seabed classes annotations. MagicBathyNet has been designed to be geographically well distributed. It’s coverage includes two very different coastal areas (in terms of water column characteristics and bottom type): i) Agia Napa area in Cyprus, covering a wide range of typical Mediterranean waters and seabed types, and ii) Puck Lagoon area in Poland, representing in a great degree Baltic Sea waters and bottom. MagicBathyNet contains 3355 RGB co-registered triplets of Sentinel-2 (S2), SPOT-6, and aerial image patches, complemented by 1244 RGB co-registered S2 and SPOT-6 doublets, 3354 DSM (Digital Surface Model) raster patches for the aerial patches and 3396 DSM raster patches for S2 and SPOT-6. Additionally, it contains 533 annotated raster patches for seabed habitat and type, facilitating supervised pixel-based classification. Each patch covers 180x180m, represented by 18x18 pixels in S2 imagery, 30x30 pixels in SPOT-6 imagery and 720x720 pixels in airborne imagery.  For the implementation code and pre-trained models visit our project page: <a href="https://www.magicbathy.eu/magicbathynet.html">https://www.magicbathy.eu/magicbathynet.html</a>  MagicBathyNet.zip file contains the original dataset presented in the respective paper. MagicBathyNet_extension_for_Swin-BathyUNet.zip file is added in the new version to support the experiments and the results presented in "Agrafiotis, P., & Demir, B. (2025).
