Microtopographic analysis is essential in the study of watershed-level spatial processes such as runoff and greenhouse gas emission. As high-resolution DEM data derived from, e.g., LiDAR technology are increasingly available, the processing and analysis of these data for microtopographic study represents a big data-driven challenge. Thus, in this study, we developed a cyberinfrastructure-enabled approach for the resolution of the big data challenge facing high-resolution microtopographic analysis. Parallel computing algorithms were implemented to harness high-performance computing power for the acceleration of the analysis steps required by the extraction of microtopographic features. The study area is a tidal wetland in South Carolina. Our experimental results indicate that the cyberinfrastructure-enabled approach can reveal the fine-scale microtopographic features efficiently.
