Landnix
Photogrammetry and thermography from the browser
Landnix turns drone photos into orthophotos, terrain models, point clouds, 3D models and temperature maps. It runs in the browser, on Windows and Mac, with nothing to install: photos are uploaded from the computer and processed on our servers in Europe. It checks the photos before upload, corrects thermal measurements image by image and produces the delivery report.

What more Landnix does
Compared with other photogrammetry software, Landnix corrects the distance in thermal measurements photo by photo and documents accuracy in the delivery report, from the browser and with nothing to install.
Computing on our servers
Processing runs on our servers in Europe: no powerful computer is needed and your own stays free.
Distance corrected in thermal measurements
Distance to the subject is taken from each photo's altitude instead of a fixed value: on our images the difference was about 2.4 °C.
Temperatures in degrees
Thermal maps with temperatures in degrees Celsius, ready to deliver.
Photos checked before upload
Photos without a position, thermal shots mixed with visible ones and RTK not always in FIX show up before upload.
Accuracy and delivery
PPK, control and check points and an automatic delivery report.
Distance correction in thermal measurements
Temperature calculation requires the distance to the subject. Without this value, standard tools apply a default of 5 metres, while a roof is normally shot from several tens of metres. Values measured on our images:
The discrepancy is about 2.4 °C, always in the same direction, and in a thermal survey it can change how an anomaly is classified. Landnix reads the altitude recorded in each image's metadata and uses it as the distance, frame by frame.
| Distance set | Mean temperature |
|---|---|
| 5 mdefault distance | 13,78 °C |
| 25 m | 13,14 °C |
| 100 m | 11,39 °C |
| 300 msaturated, same as 100 m | 11,39 °C |
Main functions
Temperatures corrected for every image
Distance is derived from each frame's altitude rather than from a single fixed value. Emissivity and the parameters used are recorded in the results.
Photo check before upload
Photos without a position, thermal shots mixed with visible ones and RTK not always in FIX are flagged before uploading and starting processing that can take hours.
Delivery report
Survey parameters, conditions and limits in a document to attach to the technical report, with the accuracy measured on the control points.
Nothing to install

Applications
Surveys and mapping
Georeferenced orthophotos, terrain and surface models, point grids and TINs ready for design software.
Construction sites and quarries
Terrain models and point clouds of the current state, to compare over time in calculation software.
Thermography
Temperature in degrees Celsius for every image and a thermal map of the whole flight, with the distance corrected image by image.
Buildings and structures
Textured 3D models from oblique photos, in OBJ and GLB, for modelling and presentation software.
From any computer
No software to install and no powerful computer needed: an up-to-date browser and a connection to upload the photos are enough.
Documented accuracy
Check against ground-surveyed control points, recorded in the delivery report.

Full list of features
Before processing
- Photo check
- Before upload Landnix reads every photo: drone, camera, GPS position, RTK FIX, gimbal tilt and shutter. It flags photos without a position, thermal photos mixed with visible ones and flights where RTK was not always in FIX.
- Upload from the browser
- A whole folder or single files, together with the flight files for PPK; an interrupted upload resumes without resending the photos already received.
Processing
- Four processing profiles
- Orthophoto and DSM/DTM; building 3D model from oblique shots; quick preview; woodland and dense vegetation.
- Precise georeferencing
- Rolling shutter correction for RTK flights, ground control points, PPK correction after the flight with base-station data, a reference system of your choice (RDN2008 included).
- True ground scale
- Product measurements are in true metres on the ground, not projection metres.
- On our servers in Europe
- Processing does not tie up the computer that starts it: the progress of every job is visible in the browser and it can be cancelled at any time.
2D outputs
- Georeferenced orthophoto
- GeoTIFF, ready for GIS and CAD software.
- DSM and DTM
- The surface and the bare ground, with a warning that under vegetation the ground is not measured.
- Grid of points and TIN
- The grid in CSV, GeoJSON, SHP and DXF; the TIN in LandXML, SHP and DXF.
3D outputs
- Dense point cloud
- LAZ.
- Textured 3D model
- OBJ and GLB.
Thermal
- Temperature of every image
- A map in degrees Celsius for every thermal shot, computed from the photo's radiometric data.
- Flight temperature map (°C)
- A temperature map of the whole flight, in addition to those of the individual images.
- Distance for each image
- Distance to the subject is derived from each image's altitude rather than a fixed value, removing a systematic error of about 2.4 °C measured on our images.
- Parameters on record
- The distance, emissivity, humidity, ambient and reflected temperature used are always written in the results.
Accuracy and delivery
- Check against control points
- Mean error, RMSE per component, horizontal and 3D, maximum error; indication of any shift or distortion of the model.
- Delivery report
- Flight parameters, conditions and limits, in PDF. Without control points, the report states that accuracy cannot be declared.
- Outputs to download
- When the job is done every output can be downloaded from the browser, through a link valid for the time of the download.
