myHadoop is a simple system for end-users to provision Hadoop instances on traditional supercomputing resources, without requiring any root privileges. Users may use myHadoop to configure and instantiate Hadoop on the fly via regular batch scripts.

points2grid

Points2Grid is a robust and scalable tool for gridding LIDAR point cloud data to generate Digital Elevation Models (DEM). Points2Grid uses a local gridding method to compute grid cell elevation using a neighborhood defined around each cell based on a search radius provided by the user.

OT_BulkAccess_COGs

OpenTopography has recently converted its entire global dataset collection to COGs. This notebook example highlights the power of Cloud Optimized GeoTIFFs (COGs) and how they can be used to reduce download filesizes as well as increase data access speeds.

PointCloud_to_STL

This notebook uses a Voxel subsampling method for point cloud data thinning. After the point cloud has been thinned, triangulation is computed to create a mesh which can be exported as a STL file and opened in a variety of 3D modeling software.
