Systems for Aerial Imaging of Avifauna and Marine Mammals

When it comes to planning your surveys, all regulatory and specific survey frameworks are considered. Our experts also take into account natural gradients and factors such as bathymetry, food availability, the distribution ranges of specific species, protected areas, etc., which allows for a scientifically reliable evaluation of the data and legally secure results.

Customized survey planning<br />

When it comes to planning your surveys, all regulatory<br />

<strong>and</strong> specific survey frameworks are considered. Our<br />

experts also take into account natural gradients <strong>and</strong><br />

factors such as bathymetry, food availability, the distribution<br />

ranges <strong>of</strong> specific species, protected areas, etc.,<br />

which allows <strong>for</strong> a scientifically reliable evaluation <strong>of</strong><br />

the data <strong>and</strong> legally secure results.<br />

Bounding Box Prediction<br />

Input Images<br />

High precision georeferencing<br />

DAISI is used to locate birds <strong>and</strong> marine mammals with<br />

very high precision. High precision georeferencing<br />

allows species abundances to be studied in the context<br />

<strong>of</strong> natural gradients <strong>and</strong> distances to anthropogenic<br />

objects such as wind turbines.<br />

DAVIS allows <strong>for</strong> fast species mapping with sufficiently<br />

precise georeferencing especially with respect to disturbance<br />

distances <strong>of</strong> wind turbines.<br />

Image aquisition<br />

Our <strong>Aerial</strong> <strong>Imaging</strong> <strong>Systems</strong> operate at 700 m (DAISI) or<br />

550 m (DAVIS) altitude. This enables safe image aquisition<br />

especially over <strong>of</strong>fshore wind farms <strong>and</strong> above the<br />

individual disturbance thresholds <strong>of</strong> seabird species.<br />

Screening <strong>and</strong> image identification<br />

Reporting / Data storage<br />

IfAÖ‘s proprietary <strong>and</strong> self-developed s<strong>of</strong>tware systems,<br />

which are enhanced by AI-based methods (see figure),<br />

enable rapid <strong>and</strong> accurate screening. Our experienced<br />

team <strong>of</strong> image analysts <strong>and</strong> ornithologists knows exactly<br />

which species are likely to occur in specific <strong>of</strong>fshore<br />

areas <strong>of</strong> the North Sea <strong>and</strong> Baltic Sea.<br />

In addition, the DAISI system allows <strong>for</strong> the determination<br />

<strong>of</strong> absolute body lengths <strong>of</strong> objects. This allows <strong>for</strong><br />

distinguishing even between very similar species based<br />

on their size (e. g. sea ducks, auks, gulls <strong>and</strong> divers or<br />

between species <strong>of</strong> marine mammals).<br />

Our highly experienced ecologists <strong>and</strong> ornithologists<br />

present the acquired data in comprehensive analyses <strong>and</strong><br />

reports, which serve as a basis <strong>for</strong> legally secure expert<br />

opinions <strong>and</strong> EIA studies.<br />

The secure permanent storage <strong>of</strong> all image data in one <strong>of</strong><br />

our redundant data centers ensures that authorities <strong>and</strong><br />

clients have access to the data <strong>for</strong> verification purposes at<br />

any time.<br />
