OpenTopography Facility's repositories
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_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.
3D_Differencing
3D differencing in OpenTopography - Author: Chelsea Scott cpscott1@asu.edu
Opal-Toolkit
Opal is a toolkit for that enables rapid deployment of scientific applications as Web services
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.
Vertical_Differencing
Vertical Differencing in OpenTopography
Intro_to_PDAL
Basic introduction to Point Data Abstraction Library (PDAL)
Visualize_Topography_Data_In_Matlab
Matlab code to read and visualize point cloud and raster topography data.
Data_Catalog_Spatial_Boundaries
Spatial boundaries of OpenTopography datasets in GeoJSON format
