[0002] Traditional tree harvesting or tree falling has long been conducted by persons and equipment based on the ground. In earlier times, from the early twentieth century and going back to the early nineteenth century, little consideration was given to the state of the forest or to the eco-system within the forest. Logging was done on a massive scale to keep up with the demand caused by the industrial revolution and the subsequent expansion of human life at the time. Depending on the terrain, tree harvesting process usually begins with experienced tree fellers cutting down a stand of trees or by using heavy ground based manned harvesting machines.

[0003] Many locations are extremely difficult to reach by land, even with the use of heavy equipment such as bulldozers, and removal of trees from such locations is expensive. Sometimes it may be desirable to harvest a single tree amongst a stand of trees, so called tree thinning, without disturbing the surrounding trees.

In other words, the data is dynamic data and maybe discretely (e.g. in batches at predetermined intervals or times) or continuously updated. It isW20320002110appreciated that any given parameters of the UAV 100a, 100b, 100c, 100d and / or the positions of the at least one trucks and / or trailer and / or load changer bed and / or self-driving pod 200a, 200b, 200c, 200d may change over time.

[0055] Data indicative of at least one tree handling parameter of the at least one truck and / or trailer and / or load changer bed and / or self-driving pod 200a, 200b, 200c, 200d may generally relate to which type of trees and how many trees it is possible for each truck and / or trailer and / or load changer bed and / or self-driving pod 200a, 200b, 200c, 200d to receive. The tree handling parameter may be at least partially pre-determined. In various example embodiments the at least one tree handling parameter may comprise load capacities of the at least one truck and / or trailer and / or load changer bed and / or self-driving pod 200a, 200b, 200c, 200d. In various example embodiments the at least one tree handling parameter may comprise a tree type handling criterion of the at least one truck and / or trailer and / or load changer bed and / or self-driving pod 200a, 200b, 200c, 200d.

[0056] Data indicative of at least one tree parameter of a tree 135 may for instance be a diameter of the at least a portion of a tree (top diameter, base diameter, mean diameter, median diameter), length of the at least a portion of a tree, tree species of the at least a portion of a tree and / or the weight of the at least a portion of a tree, dry content, age of tree, number of annual rings, distance between annual rings, color of annual rings, width of annual rings, amount of leaves, amount of fir needle, color, chemical composition of the tree, twig-free, deformation(s), cracks (dry cracks (partial or all trough), end crack, ring crack), rootstock, density, rot, discolored, dead tree, insect infested, microorganism infested, weather damage (storm, wind, fire, drought), machine damage (root, tree trunk), amount of fruits, seeds, berries, nuts, cones, flowers on the tree, form of root, root structure, root depth, root volume etc. The color of the tree may be an indicator of tree species. The color may be the color of the outer surface of the tree trunk or the color of a cut area. The form of the tree may be determined by a 3D camera. Form may comprise total volume of tree, leaves or fir needles, deformations, shape deviations etc. Tree parameters may also comprise material properties of the tree such as moisture content (%), tensile strength (MPa), flexuralW20320002111strength (MPa), compressive strength (MPa), shear strength (MPa), impact strength (KJ / m2), hardness (Brinell, Vickers, Rockwell), elasticity module (MPa), thermal conductivity (W / m°C), heat capacity (J / kg°C), Calorific value (MJ / kg), etc. In various example embodiments the at least one tree parameter may at least one of: a position of a tree, a length of at least a portion of a tree, a tree species of a tree, and a weight of a tree. In various example embodiments, the data indicative of at least one tree parameter may be provided by at least one of the UAVs 100a, 100b, 100c, 100d comprising means 102 to determine the at least one tree parameter. The data indicative of at least one tree parameter may be at least partially pre-determined.

[0057] It is appreciated data indicative of the at least one UAV parameter of the UAVs 100a, 100b, 100c, 10Od, the at least on tree handling parameter of the at least one truck and / or trailer and / or load changer bed and / or self-driving pod 200a, 200b, 200c, 200d, may be represented by the same data and / models as the data indicative of the at least one tree parameter of a tree 135 as described herein. For example, a UAV parameter may be data indicative of a length of a tree, the tree handling parameter may be data indicative of a length of a tree and the tree parameter may data indicative of a length of a tree as well. Similarities in these parameters may result in a simplified matching in various example embodiments of the methods described herein.

[0058] The method may further comprise determining S2, by the base station 120, a designated UAV 100e based on the at least one tree parameter and the at least one UAV parameter. In other words, the base 120 station, once data indicative of the parameters has been received may cause one of the UAVs 100a, 100b, 100c, 100d to be the designated UAV 100e for later steps in the method. The method may further comprise determining S3, by the base station 120 a designated truck and / or trailer 200e based on the at least one tree parameter, the positions of the at least one truck and / or trailer and / or load changer bed and / or self-driving pod 200a, 200b, 200c, 200d and the at least one tree handling parameter. In various example embodiments, determining S2 the designated UAV 100e may further comprise matching a UAV 100a, 100b, 100c, 100d with a treeW20320002112135 based on that the at least one UAV parameter is compatible with the at least one tree parameter of the tree 135. In various example embodiments, determining S3 the designated truck and / or trailer 200e may further comprise matching a truck and / or trailer and / or load changer bed and / or self-driving pod 200a, 200b, 200c, 200d with a tree 135 based on that the at least tree handling parameter is compatible with the at least one tree parameter. In various example embodiments, wherein the at least one UAV parameter may comprise positions of the UAVs 100a, 100b, 100c, 100d, determining S2 the designated truck and / or trailer 100e may further comprise matching a UAV 100e with a truck and / or trailer and / or load changer bed and / or self-driving pods 200e having a position closest to the designated UAV 100e.

[0059] The method may further comprise transporting S4 the tree 135, by the designated UAV 100e, to the designated truck and / or trailer 200e. It is appreciated that whilst the tree may be harvested prior to this step, it is not necessary that the harvesting is part of the method as such. In various example embodiments, however, the method may further comprise harvesting the tree by means of the designated UAV. Further, in various example embodiments, the tree 135 may be delimbed before transporting S4 the tree 135 to the designated truck and / or trailer 200e. Again, delimbing of the tree may be done prior to harvesting, during harvesting or after harvesting. Delimbing is not necessary a part of the method as such.

[0060] The method may further comprise unloading S5, by designated UAV 100e, the tree 135 onto the designated truck and / or trailer and / or load changer bed and / or self-driving pod 200e. In various example embodiments, the tree 135 may be directly unloaded onto the designated truck and / or trailer and / or load changer bed and / or self-driving pod 200e by means 105 of the designated UAV 100e. In various example embodiments the tree 135 may be indirectly unloaded onto the designated truck and / or trailer and / or load changer bed and / or self-driving pod 200e by means 205 of the designated truck and / or trailer 200e. Details of the means 105, 205 for unloading the tree 135 will be further discussed below.W20320002113

[0061] In Figures 2-5 schematic illustrations of various steps of methods described herein are depicted.

[0062] Turning to figure 2, an operating area 130 is depicted with an exemplary four UAVs 100a, 100b, 100c, 100d and four trucks or trailers or load changer beds and / or self-driving pod 200a, 200b, 200c, 200d. The term “operating area” is intended to be interpreted as a broader term than a forest. Consequently, an operating area 130 may include roads in connection and / or in vicinity to a forest wherein UAVs and at least one truck and / or trailer and / or load changer bed and / or self-driving pod may operate. Further, it is appreciated that fewer or more UAVs and / or trucks and / or trailers and / or load changer beds and / or self-driving pod may be present in the operating area 130 than the four depicted in figures 2-5. A singular truck and / or trailer and / or load changer bed and / or self-driving pod may be sufficient to achieve the methods and systems described. The number of UAVs and the comparative number of at least one truck and / or trailer and / or load changer bed and / or self-driving pod may be different or the same. In various example embodiments, it is appreciated that the features of UAVs and the at least one truck and / or trailer and / or load changer bed and / or self-driving pod may differ in regard to the at least one parameter UAV and the at least one tree handling parameter as well as various constructional features. Further examples are described below.

[0063] As an illustrative example, in various example embodiments the UAV 100a in figure 1 may be located at a position in the operating area 130. The UAV 100a may further have a transporting capacity, in other words, a loading capacity such that it can transport trees having certain weights and / or lengths and / or types of trees. The weight may be e.g., be 40-80 kg and the length may be e.g., 8-15 meters. These weights and lengths are common in so called “first thinning” operations. In another example the weight may be e.g., 75-150 kg and the length may be e.g., 15-25 meters. These weights and lengths are common in so called “second thinning” operations. In other words, the at least one parameter UAV relate to data indicative of the weight and / or length capacity of trees the given UAV can transport, and / or a position of the UAV. Combinations of UAV parameters areW20320002114possible. In accordance with the methods described herein, the at least one UAV parameter may be received by the base station 120 such that of methods described herein may be performed. Other UAV parameters are possible, e.g., if a UAV is electrically driven, the UAV parameter may comprise data indicative of a SoC, battery depletion rate, battery health or the like, and may be received by the base station 120 to perform the methods described herein. Analogously, if a UAV is driven by an internal combustion engine the UAV parameter may comprise data indicative of a fuel gauge, fuel depletion rate, or the like.

[0064] As a further example, the at least one UAV parameter of e.g., the UAV 100b may differ from the UAV 100a. As an example, the transporting capacity may be e.g., the UAV 100b may be adapted to transport trees having a weight or length e, whereas the UAV 100a may may be adapted to transport trees having different a weight and / or length, or the like. However, it is appreciated that each UAV may share at least one UAV parameters as well. For example, the UAV 100a and the UAV 100b may be adapted to transport trees having similar weights, lengths and types. However, the positions of the UAVs 100a, 100b may be different.Principally, the same applies for UAVs 100c, 100d and if further UAVs are present, for these UAVs as well.

[0065] As illustrated in figure 1 , each truck and / or trailer and / or load changer bed and / or self-driving pod 200a, 200b, 200c, 200d may comprise different positions within the operating area 130. The data indicative of such positions may be received by the base station 120 to perform the methods described herein.
