LiDAR Data Distribution and Processing with GEON Cyberinfrastructure:
Using cyberinfrastructure available via the GEON Project, we have built an interactive online tool set that offers distribution of LiDAR / ALSM point cloud data, digital elevation model (DEM) generation and calculation of a variety of derived products - the GEON LiDAR Workflow (GLW). The GLW is a product of collaboration between the Active Tectonics Research Group at ASU and colleagues at the San Diego Supercomputer Center as part of the GEON project. The goal of this project is to build a cyberinfrastructure-based resource to enable access to massive and computationally challenging LiDAR point cloud datasets. The GLW facilitates user interaction with these datasets by leaving the difficult processing tasks to the distributed computational resources available through the GEON Grid. Ultimately, we hope that this tool will democratize access to these very powerful data sets. We believe that this approach to LiDAR data handling and analysis represents a cutting-edge example of the application of cyberinfrastructure to next generation earth science datasets. By facilitating access to these powerful datasets, the GLW is enabling new earth surface processes research. The GEON LiDAR Workflow is currently online and is available as a beta-release to users via the GEON Portal. We are actively working to refine the workflow, improve performance, expand functionality, add datasets and polish the user interface. LiDAR DATASETS CURRENTLY AVAILABLE VIA THE GLW:
