Abstract: There is provided maintaining, at a network service operatively connected to a logging machine, master forest resource information, wherein the master forest resource information comprises prediction cells for product yield over a work area or a set of work areas, receiving, at the network service from the logging machine, logging machine measurements associated with the work area or the set of work areas, associating, at the network service, the received logging machine measurements to at least one prediction cell of the master forest resource information, determining, at the network service, based on the received logging machine measurements, a logging machine product yield for the work area or the set of work areas, modeling, at the network service, a difference between the logging machine product yield and a product yield of the at least one prediction cell, and compensating, at the network service, product yields of prediction cells based on the modeled difference.

Abstract: A method for operating forestry machinery includes providing timber units with forestry machines and an operation processor. The method also includes detecting or receiving data from an information source, where the data includes worksite preparation data, navigation data, or worksite situation data. The data is processed by the operation processor and operation parameters of the forestry machine are set based on the processing of the data. The method further includes communicating instructions to the forestry machine by the operation processor, where the instructions include the operation parameters.

Abstract: A method of and arrangement for monitoring the collection of plant material includes the following steps and apparatus for executing these steps, respectively: collecting plant location and attribute data with respect to plant material, before and/or during and/or after harvesting the plant material, providing the plant location and attribute data on a collecting vehicle adapted to collect the harvested plant material, moving the collecting vehicle to the harvested plant material based on the plant location data, collecting the harvested plant material, sensing attribute data of the harvested plant material before and/or during and/or after the collecting, and comparing the sensed attribute data with the plant attribute data and generating an output dependent on the result of the comparison.
