Entwine vs Terrasolid TerraScan

Entwine is a Linux data organization library for building indexes of massive point-cloud datasets, from desktop-scale collections to trillions of points. Its build command creates an Entwine Point Tile (EPT) dataset, a flexible octree-based format. The project describes builds as lossless, retaining points, metadata, and precision, including at terabyte scale. Entwine can index any point-cloud format readable by PDAL, with documented storage types including laszip, zstandard, and binary. Input and output can use local storage or remote sources supported through Arbiter, including S3, GCS, and Dropbox. Commands accept options on the command line or settings in JSON files. The info command gathers file metadata before a build; merge combines completed subset builds, not unrelated EPT datasets. Output is shown with Potree, Plasio, and Cesium, and EPT can be converted to 3D Tiles for Cesium. An option enables AWS server-side encryption for S3 writes. Entwine is open source under the LGPL License; Conda is recommended as the fastest installation route, with source releases also listed.

Terrasolid TerraScan is Windows desktop software for managing, processing, and visualizing point clouds, including tools for creating 3D vector data from laser points. Automatic classification routines can be refined with semi-automatic and manual tools. It can generate 3D building vector models up to LOD2 over large areas and vectorize power lines. Classification routines can be combined into macros for batch processing, and TerraBatch can run macros on other workstations over a LAN. Import and export formats include LAS, LAZ, TerraScan Binary, TerraScan Fast Binary, and user-defined ASCII formats. TerraScan supports point-cloud registration, E57, point classification, and geospatial analysis. The available editions are Full, UAV, and Lite, with network or node-locked licenses. A network license allows multiple users on the same network to share product licenses. Use cases listed by the maker include urban planning, asset management, emergency response, mapping, powerline, road, railway, water resources, forestry, and mining. Paid plans include subscriptions and perpetual licenses; a free trial is available, and no free plan is listed.
