A comparative analysis of web-based tools for landslide mapping and visualization
摘要
Effective management of landslide events requires robust mapping and visualization tools to ensure prompt responses and a thorough understanding of the situation. This study undertakes a comparative analysis of web-based tools specifically tailored for landslide reporting, mapping, and viewing, to evaluate their functionalities, usability, and suitability across diverse stakeholder groups and operational contexts. This article offers valuable considerations for users seeking specific functionalities and geographical coverage, contributing to ongoing efforts to leverage the capabilities of web-based technologies in the realm of landslide management in addressing this critical geological hazard. The research encompasses a comprehensive literature review and hands-on evaluations of selected platforms designed to meet the needs of landslide management. Key dimensions under scrutiny include data input mechanisms, spatial analysis features, visualization capabilities, user interfaces, accessibility, and customization options. Four publicly available web-based tools underwent examination in this study: the NASA Landslide Viewer, the Global Landslide Detector, the Western North Carolina (WNC) Landslide Hazard Data Viewer, and the Landslide Susceptibility Map Viewer. Each platform enables users to visualize landslide occurrences, access pertinent datasets, and scrutinize specific details about each landslide event. Notably, the Landslide Viewer, to monitor global landslides. In contrast, the WNC Landslide Hazard Data Viewer focuses specifically on North Carolina, United States, while the Landslide Susceptibility Map Viewer prioritizes comprehensive mapping within Ireland. Of all the platforms, only the Landslide Susceptibility Map Viewer actively encourages users to contribute by submitting landslide reports, thereby providing real-time observations that enhance the dataset.
