Infra Red Examples
For citrus growers, infra red imagery is a valuable tool for
assisting with the analysis of citrus health, vigour, watering patterns,
and indicators for crop yields. It has all the advantages of natural colour
high resolution photography; namely high detail and high geometric accuracy.
Colour Infra-Red photography
(orchards and vineyards)
"pseudo" AEROcolour
is an innovative technique developed by AEROmetrex
providing natural colour images from CIR film. With the use of an
automatic algorithm to convert a near infrared aerial photo into
an image that appears as natural colour.
Environmentalists, horticulturalists and viticulturalists
can have both infrared images to monitor health levels,
crops and vegetation, as well as natural coloured images for planning
and pictoral consultation
Crop Vigor (NDVI excluding soil)
Only NDVI values for vegetated areas are displayed
allowing easier assessment of crop health and vigor
Red indicates vigorous growth areas
Blue indicates poor or non growth areas
Black indicates non-vegetated (soil) areas
Normalised Difference Vegetation Index (NDVI)
Derived fromKodak Colour Infra-Red photography
NDVI strongly correlates with the amount of vegetation (bio mass)
Red areas indicate vigorous growth
Blue Areas indicate no growth
Classification of Kodak CIR photography to highlight variations within crops
Spectral analysis can provide valuable information relating to plant variety,
health and vigour.
