Geospatial Dataset of Kahramanmaraş Earthquakes (GDKE)

This dataset (GDKE - Geospatial Dataset of Kahramanmaraş Earthquakes) was collected following the February 6, 2023 Kahramanmaraş earthquakes. It contains high-resolution UAV imagery (1278×1274 px, GSD ~13 cm) captured from atlas.gov.tr across Hatay, Kahramanmaraş, and Gaziantep provinces. The dataset includes 2,551 raw georeferenced images organized by district (Nurdağı, İskenderun, İslahiye, Kırıkhan, Narlı, Onikişubat) and 266 annotated samples with corresponding YOLO-format labels for three classes: collapsed building, non-collapsed building, and tent. The dataset was used in post-earthquake collapsed building detection and risk-aware pathfinding analyses. In addition, 146 mask examples are provided in the mask_samples folder to support pixel-level semantic segmentation studies. The dataset has been used in post-earthquake collapsed building detection, risk-aware pathfinding analyses, and building-state segmentation research.
