Forestry

For Foresters by Foresters

At Aerial Agri Tech forestry is our true passion. With over 15 years experience in the sector working in Ireland, Scandanavia and Austrailia we believe there is a significant  opportunity for earth observation technology (drone and satellite) to become part of every day forest management. Our understanding of the forest environment at ground level is key to getting the most valuable data from our aerial surveys.

We ensure the highest level of accuracy by validating our results in the field. Ground control points (X) are placed throughout the survey area to improve absolute accuracy, while forest parameters such as DBH and height are recorded to help calibrate the image classification algorithms.

Parameters recorded from drone imagery surveys include, stems per hectare, height, productive area and wind damage.

 





Satellites for forestry

Medium satellite resolution imagery may not provide valuable information regarding forest parameters; such stems per hectare and height. However when used in tandem with UAV imagery, satellite imagery can be a very valuable source, providing insight into current state of the forest; especially valuable following a storm or wildfire. Clients can receive seasonal updates on the state of their forest, ensuring that they remain productive which provides piece of mind for stakeholders such as investor and insurance underwriter. Satellite imagery also provides a historical catalogue of data. When correlated with weather events risk models can be produced for each forest environment. Satellite near infrared sensors (same format as UAV sensor) provides insight into overall productivity of stand while also providing fire risk index for land surrounding the forest.  UAV data greatly enhances the output of the satellite imagery by providing a validation source for each forest including species type and productive area. AAT ensures an enhanced level of continuity between the UAV and space sensors by using similar multispectral output.

Agriculture

Insight From Above


Multispectral sensors allow us to present a unique insight into agricultural land. Vegetation indicies enable the classification of land, based on species, productivity and vigour. The combination of high resolution and elevation imagery are used to accurately calculate areas. Fertilisers maps may also be created allowing for the prioritisation of application for areas under stress .

Key farm parameters collected during drone flight include, un/productive area, total farming area, fertiliser maps, drain and flood analysis.

Insurance

Risk and Damage Assessment


Aerial Agri Tech provides forest owners and insurance underwriters with a platform to assess the extent of forest damage in near real time. Through the use of satellites we calculate the extent of damage at regional/national scale using bespoke image processing algorithms. Drone technology allows for individual tree calculations at stand level providing an accurate monitory value of damage timber. This approach is significantly faster than the traditional method of forest damage assessment, its also much safer as in-field observations in dangerous environments are not required.

The historic catalogue of satellite and meteorological data allows us to correlate damage with specific weather events. By doing this we have identified the most vunerable forest characteristics that lead to damage. By combining geospatial datasets we have created risk models for specific forest locations throughout the country.   

 

Environmental and Aquatics

Mapping without boundaries


Satellites in tandem with drone imagery offer insight into position of sediment banks and flood monitoring along with risk assessment.Multispectral imagery identifies and classifies invasive species i.e macrophyte detection and classification. Elevation imagery allows for a 3d representation of river banks and may also be used to evaluate flood risk assessment. Aerial Agri Tech have created a methodology whereby elevation data collected by drone can seamlessly be merged with bathymetry data for unique mapping of the aquatic zones.

Aerial Agri Tech conduct surveys on behalf of biologists and ecologists who wish to efficiently map and monitor sensitive landscapes. This approach enables invasive or protected species to be identified without disturbing the environment.
