Neurones 3D vs DJI Terra
Looking for a DJI Terra alternative? Neurones 3D is free, offline point cloud and Gaussian splatting software for Windows: the free viewer runs every process, from AI classification to dimensioned floor plans, and a one-time paid edition saves the results.
DJI Terra is DJI’s desktop reconstruction software: photogrammetry, Gaussian splatting, multispectral maps and processing of data from DJI Zenmuse LiDAR payloads, built to work with DJI Enterprise drones.

The short answer
Choose Neurones 3D if you already have point clouds, from DJI or any other sensor, and want to classify them with trained models, build terrain and contours, measure change with M3C2 and draw plans, fully offline with no account and a free viewer that runs every process. Choose DJI Terra if you fly DJI Enterprise drones and need the reconstruction step itself: photogrammetry, Gaussian splats, Zenmuse LiDAR processing with PPK, and multispectral maps from the drone maker.

Where Neurones 3D is stronger
- No account, no activation and no internet connection at any stage; DJI Terra’s online licences need a stable connection, and its trial needs one too.
- The free viewer runs every process on your own data; the DJI Terra trial lasts one month and stops at 500 photos and 8 GB of LiDAR data.
- M3C2 change detection and automatic floor plans with sections and elevations; neither appears in DJI Terra’s published feature list.
Where DJI Terra is stronger
- Photogrammetry and Gaussian splat training from drone photos, with city-scale and cluster reconstruction; N3D does not process photos or train splats.
- Tight integration with DJI drones and Zenmuse LiDAR, including PPK and centimetre-level accuracy without ground control points.
- Multispectral vegetation index maps and agricultural prescription maps.
Who should choose which
Choose Neurones 3D to take a point cloud or a splat capture to a finished deliverable on your own machine: classified LAS, a dimensioned floor plan with sections and elevations in DXF, a DTM with contours, a change map or a report, without an account, an upload or a subscription. Every figure it publishes is measured; see the benchmarks.
Choose DJI Terra: Survey and inspection teams flying DJI Enterprise drones and Zenmuse payloads who want reconstruction, LiDAR processing and Gaussian splats from the drone maker’s own software.
Questions
Is DJI Terra free?
DJI Terra: Agriculture, 1 year, 3 devices: 300 € on the DJI Store; Standard and Flagship: price on request from DJI dealers. Free use: One-month trial: up to 500 photos and 8 GB of LiDAR data, one computer, internet connection required. Neurones 3D’s free viewer opens, views and runs every process; writing results out needs a paid edition bought once.
Does DJI Terra work offline?
DJI Terra: partly. Offline licences run paid features without internet once bound to a computer; online licences need a stable internet connection. Neurones 3D: yes. No account, no internet connection, no telemetry.
Can DJI Terra classify point clouds with AI?
DJI Terra: partly. LiDAR point cloud classification is listed (Standard, Flagship); the method and classes are not described. Neurones 3D: yes. Four trained models ship in every build: indoor, aerial LiDAR, powerline, streetscape; a confidence per point.
Does DJI Terra support Gaussian splats?
DJI Terra: yes. Trains Gaussian splats from photos; exports PLY and B3DM (3D Tiles). Neurones 3D: yes. Opens PLY and SPZ splats, converts them to points, meshes them; does not train splats.
What is the best alternative to DJI Terra?
Choose Neurones 3D if you already have point clouds, from DJI or any other sensor, and want to classify them with trained models, build terrain and contours, measure change with M3C2 and draw plans, fully offline with no account and a free viewer that runs every process.

How this comparison was made
Written by the maker of Neurones 3D, so read it as such. DJI Terra's column comes only from DJI's published documentation and listings, read on 2026-09-24; where we found nothing, the cell says "not stated". Neurones 3D's column comes from its own guides, which give the limits too. If something here is wrong or out of date, write to howto@learngeodata.eu and it will be corrected.
