3D_Differencing
3D differencing in OpenTopography - Author: Chelsea Scott cpscott1@asu.edu
myHadoop
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.
Opal-Toolkit
Opal is a toolkit for that enables rapid deployment of scientific applications as Web services
OT_3DEP_Workflows
Jupyter Notebook-based workflows for programmatically accessing, processing, and visualizing 3D Elevation Program (3DEP) lidar data
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.
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.
RayShader
Notebook created by OpenTopography highlighting RayShader for 2D & 3D topographic data visualizations.
RiverREM
Make river relative elevation models (REM) and REM visualizations from an input digital elevation model (DEM).
Vertical_Differencing
Vertical Differencing in OpenTopography
OpenTopography Facility's Repositories
OpenTopography/RiverREM
