Aerial Engineering Australia uses the latest in drone technology to give farmers an up-to-date aerial perspective of crop fields.
Instead of walking or driving through fields, which can be inefficient and time consuming, Aerial Engineering Australia can fly and process Orthomosaic Agricultural Maps of over 350 acres on site in under an hour. These orthomosaic images allows farmers, in real time to locate problem areas of crop and vegetation as well as measure the areas in order to improve the efficiency with distribution of irrigation, fertilisers, pesticides and more.

As well as producing RGB Orthomosaic Images (see above), we are also able to produce TGI (Triangular Greenness Index) orthomosaic and VARI (Visibly Atmospheric Resistant Index) orthomosaic. This index’s provide a highly contrasting images to clearly define problem areas within the surveyed field to even further increase efficiency for farmers.
Triangular Greenness Index (TGI)
Visibly Atmospherically Resistant Index (VARI)
Triangular Greenness Index (TGI) is a vegetation index that is sensitive to the differences in leaf chlorophyl content. This works by measuring the reflectance of Red, Green and Blue wavelengths, the index produces an an orthomosaic image that hi-lights the level of chlorophyl content within the leaves.
Visibly Atmospherically Resistant Index (VARI) is designed to minimise atmospheric effects of blue wavelengths on visible images to emphasise green vegetation. This is done by calculating the ratio of green against red and blue for each pixel within the image. This helps farmers easily differentiate between healthy and unhealthy vegetation.
