What DroneField does

DroneField is a complete, locally-running drone-processing application for drone-spray service providers, precision farms, and commercial surveyors. A single tool covers the full pipeline from drone imagery to DJI Agras / XAG / tractor-compatible application maps.

Orthomosaic creation

The classic high-resolution RGB orthomosaic, ready to view in the built-in map view or export to QGIS. The target GSD is configurable per project between 4 and 20 cm/px (default 5 cm/px).

Digital Surface Model (DSM)

Generated from the photogrammetric surface reconstruction — the digital surface model with contour lines and colour-coded elevation ranges. Ideal for assessing canopy height or understanding the terrain.

Vegetation indices

From imagery captured with the DJI Phantom 4 Multispectral or Mavic 3 Multispectral, DroneField computes the following multispectral (MS) indices:

• NDVI (Normalized Difference Vegetation Index)
• GNDVI (Green NDVI)
• NDRE (Normalized Difference Red Edge)
• EVI (Enhanced Vegetation Index)
• VARI (Visible Atmospherically Resistant Index)

From the RGB orthomosaic of any supported drone it computes the RGB indices VDVI, NGRDI and ExG (plus VARI in RGB-only projects) — generated on first use, no multispectral camera needed.

In multispectral projects the values can be visualised with preset ranges: Healthy stand, Stress, Water/Soil — switchable with a single click. Export to PNG, JPEG or GeoTIFF (QGIS-compatible). See Vegetation indices.

Field boundaries and obstacles

Draw polygons and circles, or import them onto the map:

• Field boundary — the outer contour of the treatable area.
• Obstacle — tree, pole, overhead wire that the drone must avoid.
• No-spray zone — riverbank, neighbouring plot.

Import from: KML, ESRI Shapefile (SHP) in any projection (EOV, WGS84, UTM and everything else PROJ recognises), or from a previous DroneField project.

Export to: DJI Agras (drone or USB), ISOXML V3/V4 (drone or USB), XAG drones, ESRI Shapefile.

AI vegetation analysis (AI VRA)

The vegetation index panel’s AI analysis button opens a short wizard, then the Luna assistant picks the most suitable index, zones the field, proposes per-zone doses with an agronomic explanation and generates a PDF report with an expert approval block. See AI vegetation analysis.

AI field boundary

Click the field on the orthomosaic and the on-device segmentation model draws the field boundary from a few points you click inside the field (⌥-click excludes an area) — no internet needed; the result opens for normal vertex editing. See AI field boundary.

Application map (VRA)

From the vegetation index, DroneField generates a gridded application map with a single click. You assign zones (e.g. less fertiliser to the healthy stand, more to the stressed parts), enter the litre/hectare or kg/hectare values, and export to:

• XAG Spot Spraying
• XAG VRA precision map
• DJI VRA precision map
• Hardi VRA Shapefile
• ABZ Innovation (L-S series)
• PNG / JPEG image formats

3D Map

The processed field as a smooth 3D terrain surface — with the orthomosaic or NDVI draped over it, orbit (showcase) animation, and MP4 flythrough export for demos and client reports. See 3D Map.

Survey report (PDF)

One click produces a professional PDF report of the project, covering the safety zone, RGB orthomosaic, DSM, vegetation indices, field boundaries and application map — ready to hand to a client or file in your archive.

Processing

A single Start process button runs the processing — Bundle Adjustment, sparse DSM and orthomosaic render. Optional switches in the processing panel: Multispectral processing, Terrain mode (hilly fields), High resolution (native) and Illumination balancing. See Processing.

What DroneField does NOT (yet) do?

We are upfront. Keep the following in mind:

• DJI drones only (P4R, P4M, M3E, M3M, Matrice 4E/4T, and in beta the Matrice 5TD and the M300/M350 RTK + Zenmuse P1). Accurate (RTK) image positions are needed for reliable results.
• No cloud sync. Projects live on your machine.
• Runs on macOS, Windows and Linux — with identical features.
• Full 3D modelling (textured mesh, MVS) is not a goal; DroneField is tuned for precision-agriculture workflows.
