Entwine vs Global Mapper

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.

Global Mapper is a desktop GIS application for geospatial data processing, spatial analysis, geodetic workflows, and preparing maps for deployment. It supports more than 300 vector, raster, elevation, and point cloud formats without add-ons or additional licenses. The Essentials plan covers data viewing and conversion, coordinate transformation and reprojection, and streamed online data sources. Advanced adds terrain and vector analysis, scripting, geodetic analysis, and cartographic production. Professional adds lidar and point cloud processing, drone photogrammetry, complex imagery and raster analysis, automated breakline extraction, and AI/ML image classification. Lidar tools include feature classification, noise removal, point cloud thinning, and vector feature extraction. GeoCalc provides more than 12,000 geodetic definitions and supports modernized NSRS and CSRS. AI-assisted extraction can identify roads, buildings, vegetation, power lines, and other features. It exchanges data with ArcGIS formats, exports to Avenza Maps for offline field use, and supports a workflow with MAPublisher and Adobe Illustrator. Plans start at $599/user/yr; a 14-day trial is listed.
