3d_differencing

3D differencing in OpenTopography - Author: Chelsea Scott [email protected]

data_catalog_spatial_boundaries

Spatial boundaries of OpenTopography datasets in GeoJSON format

data_qa-qc

intro_to_pdal

Basic introduction to Point Data Abstraction Library (PDAL)

libicp

OpenTopography fork of the C++ Library for Iterative Closest Point fitting. Updated by Chelsea Scott [email protected] - LASlib integration

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).

segment_anything_model_topography

Segment Anything Model for Topography Data

vertical_differencing

Vertical Differencing in OpenTopography

visualize_topography_data_in_matlab

Matlab code to read and visualize point cloud and raster topography data.
