Species Identification

Using aerial remote sensing technologies Aerial Surveys is able to identify and locate different species of trees.This is useful in determining the number and position of sub-species within a forest, or finding the extent and nature of weed cover prior to planting for example.

Where insect infestation has occurred and a specific host species of tree is identified,  Aerial Surveys technology can rapidly locate and map where the host trees are.

In indigenous forest, specific species can be located and mapped for selective extraction.

Health monitoring

Every year forest owners lose value from their forest asset through poor tree health and the effects of disease or pest infestation.

Trees exhibit distress in their leaves which the Aerial Surveys remote sensing technologies can detect and locate on a map.  Knowing the extent of disease or infestation in a forest allows the forest manager to accurately target sprays and other treatments, saving time and money.

In some instances it can be possible to identify specific disease from the air, but it may still be necessary to ground truth the actual disease.

Products and Services | Aerial Surveys

In addition to traditional GIS data, aerial photography and imagery that we have been supplying to our clients for more than 18 years, we are continually exploring new technologies and developing new tools and products to advance the quality of decision making by our clients.


Solutions | Aerial Surveys

There are so many applications that can benefit from geospatial components and there is a popular misconception that this is a very expensive industry requiring highly skilled and expensive specialists. Aerial photography, remote sensing, mapping as well as our Points of Interest databases allow you to use disparate systems and databases to come up with quality information.


LiDAR/ALS | Aerial Surveys

This data is referred to as intensity data and when greyscale readings are applied to the measurements, an intensity image is created, effectively delivering a medium resolution black and white ortho image. Depending upon the area of interest, size, shape and type of terrain, the parameters within the LiDAR system (pulse rate, swath width and scan angle) are set to achieve the best solution for each project.


Forest Mapping | Aerial Surveys

This information allows planners, planting contractors, road constructors and harvesters to plan activities appropriate for the terrain, highlighting ridge lines, watercourses, slope and aspect, and other topographical features. Accurate stand boundaries will reflect the gross area in contention, but the productivity is determined by the proportion of that stand that is growing trees – the net stocked area.
