Temperatures

Measure crop temperature

From the drone's radiometric thermal photos, a map of the field in degrees Celsius, with the actual distance of every shot in the calculation.

A plant short of water closes its stomata, transpires less and warms up. That is why a temperature map shows water stress before it is visible, together with waterlogging, irrigation that does not reach and canal leaks. Agronix reads radiometric thermal photos, converts every pixel into degrees Celsius and builds the field map.

Map in °C

A temperature on every pixel

Each thermal photo becomes a map in degrees Celsius with the actual shooting distance, taken from the drone's laser rangefinder or from flight altitude. The photos are then merged into the field map with a cool-to-warm scale and statistics for every field.

Thermal surveys

Every thermal survey on one page

The Temperatures page lists the thermal surveys of every farm with date, fields and values. Each map opens on the field and downloads as GeoTIFF for GIS software.

How it works

Fly with thermal

Best in the warm hours, when differences are strongest.

Upload the photos

Agronix recognises radiometric thermal photos.

Read the map

Warm zones transpire less, cool ones may be wet.

Go and check

The warmest spots are checked in the field.
