A gardening and/or forestry system includes a distance measuring system, including a first distance part and a second distance part, wherein the second distance part is configured to be carried on a body of a gardener and/or forestry worker. The distance measuring system is configured to exchange a measuring signal between the first distance part and the second distance part and to measure a distance between the first distance part and the second distance part based on the exchanged measuring signal. An output device is configured to output information based on the measured distance to the gardener and/or forestry worker.

A system assists during execution of a sequence of cuttings in a tree, wherein, during a cutting sequence, a first cut in the tree is followed by a second cut in the tree At least a part of an ideal course of the second cut depends on at least a part of a course of the first cut. An identification device identifies at least the part of the course of the first cut in the tree. A precalculation device precalculates at least the part of the ideal course of the second cut in the tree based on the identified part of the course of the first cut. An output device outputs cutting information for executing the second cut based on the precalculated part of the ideal course of the second cut.

A system assists during felling of a tree. A provision device provides a property of the tree and/or a property of an environment of the tree, identifies at least part of a course of a cut in the tree for felling the tree and/or identifies a position and/or an orientation of a cutting apparatus executing the cut. A determination device obtains felling information related to an ideal felling direction of the tree, compares the identified part of the course to an obtained part of an ideal course of a cut to be executed in the tree for felling the tree in the ideal felling direction, compares the identified position and/or the identified orientation of the cutting apparatus to an obtained ideal position and/or an obtained ideal orientation of the cutting apparatus, and obtains cutting information based on the comparison. An output device outputs the obtained felling information and cutting information.

Embodiments described herein are directed to an apparatus for determining a direction in which a tree will fall and a method for using the apparatus. The apparatus may comprise a plate including a substantially straight edge suitable for alignment with a vertex formed by a top cut and a bottom cut of a notch cut into a tree and a substantially level bottom surface suitable for stable placement upon the bottom cut of the notch. In some embodiments, the plate may define an internal cavity sized to accommodate a laser light generator. In other embodiments, a rotatable housing including a cavity sized to accommodate a laser light generator may be adjoined to the plate. Embodiments may permit a laser light generator contained within the cavity or the housing to emanate a beam of laser light in a direction that is substantially perpendicular to the substantially straight edge of the plate.

A log marking device (1) comprising a log marking tool (2) with a striking head (10) provided with adjustable marking members, and a setting unit (3) with setting members for setting the marking members in desired positions or states. The setting unit also comprises: —a housing (30) with a seat (31) for receiving the striking head; —actuators for controlling the movements of the setting members; and—an electronic control unit for controlling the actuators. The striking head (10) is moveable into a setting position, in which the striking head is received in the seat (31) of the setting unit with each marking member in contact with the associated setting member so as to allow the setting unit (3) to set the positions or states of the marking members by operation of the actuators.
