SENRA
Beyond the visible.
Multispectral drone monitoring for apple orchards and vineyards in South Tyrol.
A real survey
The same orchard read with different indices: each shows what the photo does not.
NDVI
Shows overall vegetation vigour and where it changes from one zone to another.
Demonstration survey of 4 October 2026 with a DJI Mavic 3M. GPS positioning without RTK correction: error of about 0.2 m.

Three flights per season: bud break, flowering, fruit set.
All growth stages, annual report and on-site meeting.
Every proposal is assessed case by case.
Frequently asked questions
What is multispectral monitoring?
A drone with sensors that record, besides visible light, the red edge and near-infrared bands. From these bands we compute indices such as NDVI, NDRE and OSAVI, which show plant vigour in a way the naked eye cannot see.
What can I learn from the maps?
Where areas of a parcel differ in vigour and chlorophyll content. The map does not say why: the cause is checked in the field.
Which crops do you work on?
Apple orchards and vineyards in South Tyrol. For other crops, write to us: we assess each case individually.
How accurate is the survey?
In the demonstration survey: 0.59 cm per pixel on the ground at a flight height of 21 m. GPS positioning is without RTK correction, with an error of about 0.2 m.
When do you fly?
The SEASON service includes three flights: bud break, flowering and fruit set. The YEAR service covers all growth stages, with an annual report and an on-site meeting.
