The aligned plant locations maybe mapped to a two-dimensional (row, line) coordinate system and where a row of plant locations may be composed of one or more row segments of contiguous plant locations. The characteristics data may comprise a plantation map of the agricultural field. The user interface may comprise a row or row plant zone button and a line or line plant zone button (figure 5a), wherein hitting on the one or both buttons causes receiving user inputs. Also disclosed is a device for generating characteristics data and a non-transitory computer-readable medium causing a device to perform the method.
