OT_3DEP_Workflows
OT_3DEP_Workflows PublicForked from cmspeed/OT_3DEP_Workflows
Jupyter Notebook-based workflows for programmatically accessing, processing, and visualizing 3D Elevation Program (3DEP) lidar data

OT_BulkAccess_COGs
OT_BulkAccess_COGs PublicOpenTopography 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 …

PointCloud_to_STL
PointCloud_to_STL PublicThis 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 a…

3D_ICP_Differencing
3D_ICP_Differencing PublicThis repository provides tools for on-demand 3D topographic change detection using a windowed iterative closest point (ICP) algorithm. It calculates displacement and rotation fields from high-resol…
Repositories
- Data_Catalog_Spatial_Boundaries Public
Spatial boundaries of OpenTopography datasets in GeoJSON format
- opentopography_point_elevation_notebook Public Forked from mattbeckley/PointElevAPI_Notebook
A Jupyter notebook demonstrating how to use OpenTopography's Point Elevation API.
- STAC-Examples Public
Example Notebooks for Accessing OpenTopography's SpatioTemporal Asset Catalog (STAC)
- OpenTopography-DEM-Downloader-qgis-plugin Public Forked from knwin/OpenTopography-DEM-Downloader-qgis-plugin
QGIS plugin to dwonload DEMs from OpenTopography.org
- topo-change-uncertainty Public Forked from Cassandra-Brigham/topochange
Open Source Python package for quantifying spatially correlated uncertainty in lidar topographic change detection. It decomposes vertical differencing error into bias, correlated, and uncorrelated components across spatial scales using nested variogram models and propagates uncertainty over user-defined regions.
- OT_BulkAccess_COGs Public
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.
- OT_3DEP_Workflows Public Forked from cmspeed/OT_3DEP_Workflows
Jupyter Notebook-based workflows for programmatically accessing, processing, and visualizing 3D Elevation Program (3DEP) lidar data
- OT_Tile_Index_Search Public Forked from mattbeckley/OT_Tile_Index_Search
This repository contains a Jupyter notebook that demonstrates how to use OpenTopography tile indexes to programmatically find and download lidar data for specific regions. It also presents a cloud-native PDAL workflow for streaming and processing point cloud data on-the-fly without the need for local storage.
- 3D_ICP_Differencing Public
This repository provides tools for on-demand 3D topographic change detection using a windowed iterative closest point (ICP) algorithm. It calculates displacement and rotation fields from high-resolution topographic point clouds to quantify surface deformation, especially along active faults.
