OpenTopography Tool Registry
Welcome Guest ( Sign Out )
The OpenTopography Tool Registry provides a community populated clearinghouse of software, utilities, and tools oriented towards high-resolution topography data (e.g. collected with lidar technology) handling, processing, and analysis. Tools registered below range from source code to full-featured software applications. We welcome contributions to the registry via the Contribute a Tool page.
Appearance of a tool in the OpenTopography Tool Registry does not imply endorsement, recommendation, or support, by the NSF OpenTopography Facility and is meant simply as a service to our users. OpenTopography does not guarantee the completeness or accessibility of specific content and links contributed by users. If you have been directly involved with the development of a registered tool and are not the original contributor of the tool to the registry, please email info@opentopography.org to supply updates or modifications to its entry.

| 1 | SPD Software Library (SPDLib) | 24 May 2012 | Software Suite |  |
|
Keywords: SPD, SPDLib, LiDAR, TLS, ALS, Full, waveform, Discrete, return, points
License: GNU General Public License Description: SPDLib is a set of open source software tools for processing laser scanning data (i.e., LiDAR), including both discrete return and waveform data captured from airborne and terrestrial platforms. The aim of the software is provide you, the user, with the tools you need to process these data. The software has grown from research carried out at Aberystwyth University and Queensland University concerning the processing of LiDAR data for vegetation analysis and has continued to grow. One of the key features which differentiates this software from other LiDAR software is the ability to process and store full waveform datasets alongside traditional discrete return data |

| 2 | NERC-ARF DEM Scripts | 7 Jul 2016 | DEM generation |  |
|
Keywords: DTM, DSM, LAS, GRASS
License: GNU General Public License Description: A collection of scripts developed by the Natural Environment Research Council (NERC) Airborne Research Facility Data Analysis Node (NERC-ARF-DAN; formerly ARSF) for generating DEMs from point clouds. Through command line tools or Python functions the ARSF DEM Scripts provide a common interface to generate DSMs or DTMs from LAS files using GRASS, SPDLib, points2grid, FUSION or LAStools. When using SPDLib, FUSION or LAStools will classify ground returns to produce a DTM (note license required to produce a DTM using LAStools). Additional utilities are available for manipulating DEMs (e.g., patching with a courser resolution DEM to fill in gaps) using GRASS. |
