Trees and heights

Count and measure the trees

The survey with heights finds every tree and measures its height, canopy and volume. From the same terrain model: rice paddy levelling and stockpile volumes.

Book a demo All features

For orchards, olive and hazelnut groves the survey with heights builds the surface model and the terrain model. The difference gives the height of everything above the ground: Agronix finds the tree tops, draws each crown and measures height, diameter, vigour and volume. The same models are used for rice paddy levelling and for the volumes of stockpiles, silage clamps and manure heaps.

Trees

Every tree with its own record

For every tree height, crown diameter, vigour and crown volume; for the field the count, totals and per-hectare values. Trees appear as points on the map and download for other software. Crown volume is used to dose treatments on the actual plant.

Tree prescription

Spray only where the crown is

From the counted trees comes a prescription for the spraying drone: the rate goes only on cells under a crown, with a margin, and elsewhere you choose the rate, usually zero. The file loads from the microSD and is used in the drone's orchard operations.

Terrain

Level paddies and measure stockpiles

Levelling reads the terrain model in one-metre cells, compares it with a flat plane or with the field's slope and tells how much of the field lies within ±2.5, 5 and 10 cm, how much cut and fill is needed, with contour lines. For stockpiles, silage clamps and manure heaps you draw the perimeter and Agronix computes the volume.

In detail

Check: On an olive grove with 2,426 hand-marked crowns: precision 0.92, trees found 0.85.
Crops: Orchards, olive and hazelnut groves and row trees with separate crowns.
Levelling: 1 m cells, flat or sloped plane, GeoTIFF of deviations in cm.
Volumes: Base computed on the heap's toe or at a fixed height; tested on a cone of known volume within 1 %.
