LiDAR surveys allow large scale mapping to be done with a level of cost-effectiveness not previously available. It possesses the capability to map ground features under dense vegetation and with multiple surveys over time, LiDAR data can be used to monitor the growth and vitality of a forest or commercial plantation.
LiDAR is unique in its ability to measure the vertical structure of forest canopies. It can predict canopy bulk density and canopy base height, while also mapping the ground beneath the forest. These datasets are useful, amongst other things, for measuring canopy fuel capacity and generation of fire behaviour models. Another use of LiDAR is the measurement of peak height to estimate the root expanse. This is a valuable tool for insurers when considering risk associated with houses in a particular area.
Within forested areas, LAS point clouds can be used to classify features such as water, vegetation (high, medium and low), roads, bridges, buildings etc. These point clouds can also be merged with an image to produce a file where each point is coloured according to the feature it represents.
LiDAR can be used to monitor the growth rates for orchards and crops, a valuable tool for farmers. We can facilitate combined surveys where a large number of farms are captured and processed in a single survey, with data cut up and allocated to individual farm owners, to make the project cost-effective.
