A New Large-Scale Benchmark for Change Detection and Landslide Mapping! The Global Very-High-Resolution Landslide Mapping (GVLM) dataset is the first large-scale and open-source VHR landslide mapping dataset. It is available for free to researchers for only non-commercial use.

For change detection tasks, current open-source datasets mainly focus on building extraction (e.g., WHU building dataset and LEVIR-CD dataset) (Chen and Shi, 2020; Ji et al., 2018) and urban development monitoring (e.g., SECOND dataset, Google dataset and CDD dataset) (Yang et al., 2022; Peng et al., 2021; Lebedev et al., 2018), whereas datasets for natural disaster monitoring have been seldom investigated.

Therefore, we sought to present the GVLM dataset, the first large-scale and open-source VHR landslide mapping dataset. It includes $17$ bitemporal very-high-resolution imagery pairs with a spatial resolution of $0.59$ m acquired via Google Earth service. Each sub-dataset contains a pair of bitemporal images and the corresponding ground-truth map. The total coverage of the dataset is $163.77 km2$. The landslide sites in different geographical locations have various sizes, shapes, occurrence times, spatial distributions, phenology states, and land cover types, resulting in considerable spectral heterogeneity and intensity variations in the remote sensing imagery. The GVLM dataset can be used to develop and evaluate machine/deep learning models for change detection, semantic segmentation and landslide extraction.

It is available at Baidu Drive, or Google Drive. We also provide a single-temporal version for landslide extraction or detection, which is available at Google Drive. In the future, we will continue promoting the establishment of a worldwide landslide mapping system by acquiring more remote sensing image data in landslide-prone areas. Hope you can join us!

We also provide a simple demo for image clipping, model training and testing. Please refer to LandslideMappingDemo. Users can split images into desired-size patches and generate their own train, validation, and test sets.
