High-Resolution Elevation Data for Vulnerability Assessment of Roads in a Changing Climate

Climate adaptation of road infrastructure becomes increasingly important as extreme weather events increase in frequency and intensity. Climate adaptation studies often require a vulnerability assessment of the road network, to identify where adaptation measures are most needed or have the most impact. This, in turn, requires high-resolution elevation data, which is not always readily available or costly to obtain. The authors describe a new methodology, dubbed ParTerra Roads, which fuses data from freely available datasets with global coverage to create a high-resolution elevation dataset for any area in the world. It facilitates a participatory approach to improve stakeholder involvement but can also function as a stand-alone tool. The authors demonstrate its use and validate it using a high-quality LiDAR-based dataset, showing its potential and limitations. Both aspects are strongly linked to the input data. Further research and development are key to improve its usability
