Landgate has a large library of Near-Infrared (NIR) aerial imagery. Our NIR imagery capture commenced in 2007 and is updated each year.
Near-Infrared (NIR) aerial imagery can be used to:
- improve vegetation asset management of sports ovals, street trees, parks and bush land
- localise and measure environmental stresses on plant health such as pollution, water deficiency, nutrient stress and diseases and
- control vegetation health impacted by floods, drought, bushfires and weeds.
Local governments are using NIR imagery to identify:
- temporary and permanent swimming pools
- unauthorised vegetation clearing.
Practical applications of NIR imagery are shown below.
This image identifies all vegetation
This image provides an overview of vegetation health, with red being the most healthy, though to green where vegetation is under stress.
NIR can be used to easily detect permanent and temporary (above ground) swimming pools.
Algorithms can be used to isolate vegetation based on approximate heights. The trees (shown in green) are higher than the grasses at ground level (in pink).
This image shows areas of vegetation increase or decrease from one year to another. It can potentially be used to identify areas of unauthorised clearance.
