ABSTRACT

The present work contributes to the process of modernization of traditional geomorphological mapping, a fundamental tool for the assessment of the hazard degree of natural processes for the planning, of works and infrastructures. Starting from a traditional and detailed geomorphological survey and through elaborations in a GIS environment, this paper presents a multiscalar cartography model, characterized by a ‘full coverage’ representation of landforms. These characteristics make it possible to upscale or downscale processes and landforms and to use different information levels created in a hierarchical form. The test site for the experimentation is located on the Adriatic side of central Italy and is represented by a small catchment, about 13 km² large. All geomorphological features and information have been organized as elements and attributes within digital geomorphological information layers, following structured on a Digital Terrain Model derived from LiDAR; this new product is here proposed also as web-browser version.

摘要

本工作为传统地貌制图的现代化进程做出了贡献，这是评估规划，工程和基础设施自然过程危害程度的基本工具。从传统的详细地貌调查开始，到GIS环境中的细化，本文提出了一种多尺度的制图模型，其特征是“完全覆盖”了地貌。这些特性使得可以按比例放大或缩小过程和地貌，并可以使用以分层形式创建的不同信息级别。实验的测试地点位于意大利中部的亚得里亚海一侧，以一个小流域为代表，约13 km ²大的。根据从LiDAR衍生的数字地形模型，将所有地貌特征和信息组织为数字地貌信息层内的元素和属性。在这里，也建议将此新产品作为Web浏览器版本。
