Tree analysis

Years of proven know-how in applied tree biomechanics with the clarity of a 3D environment.

What is Adbian?
Public perceptions of the level of risk caused by trees are often exaggerated. Concerns about health or property sometimes lead to the felling of trees that simply grow a little bit on their own.
Such fellings leads not only to removals of biologicaly valuable micro-habitats but also incurs unnecessary costs. Thanks to Adbian software, you can make data-driven decisions reducing financially and environmentally unsound preventive felling practices.
3D tree analysis
To assess the stability of a particular tree, we use an analysis that combines the knowledge of applied tree biomechanics with the clarity of  3D environment.  The analysis takes place on several levels.The output of the calculation is, in addition to the 3D model, an expression of the overall stability of the tree in the form of a safety coefficient.
The safety coefficient indicates whether a tree with specific parameters can safely exist in a given location, even under the on slaught of statistically expected gale force. Should it turn out the stability of a tree is insufficient, stabilization measures are proposed in the form of crown reduction pruning. The next step is to measure the effect of stabilization measures on the stability of the tree . Only after we have exhausted all possible solutions, the proposal for tree removal may come into consideration, including the calculation of possible compensation in the form of new planting.
level 01

Dendrology

The first level of tree stability assessment combines elements of a classical dendrological survey (tree assessment) with an overall analysis of the tree based on its shape, dimensions and material properties of the wood.

Dendrology +

The second level of the survey enables a significant increase in the accuracy of the tree stability calculation thanks to the assessment of the tilt of the stem and the distribution of the crown volume (asymmetry). This more accurate calculation uses calibrated photographs (pictures of the whole tree and details of its stem) providing a range of dendrometric parameters to obtain a rod model of the stem. The rod model can be used in repeated measurements to look for differences and tendencies to failure of the stem or whole tree. This represents a new approach to analyzing the resistance of trees to uprooting. The detail and outputs from processing of these pictures goes well beyond a simple visual assessment.

Stem Scann

The third level extends the spectrum of data investigated by 3D SCANN to include detailed trunk geometry, which enables significantly more accurate tree stability calculations. This holds true especially for trees with open cavities or highly irregular trunk shapes. Changes instability are analysed by repeated measurements not only by using a rod model(as in the case of Dendrology+), but also by tracking compensatory growth in individual parts of the tree stem.

Device
testing

The fourth and most advanced level of the tree stability assessment combines photographic analysis with the 3D SCANN of the trunk with modern device-supported diagnostic methods. The accuracy of the tree stability analysis is enhanced and subsequently verified by several interrelated methodological procedures. The device-supported measurements themselves can include pulling tests and acoustic tomography of the stem, as well as the possible use of invasive technologies (resistograph measurements). Level 4 therefore provides extended level of analysis, based not only on outside shape of the tree stem, but also on the survey of the internal quality of wood of load-bearing elements
