A work information setting system (1) includes: an input unit (41) that is used for work information setting control; and an output unit (43) that outputs information pertaining to the work information setting control. The work information setting control sets work information (D). The work information (D) includes position information (W) used when a work machine (10) performs work. The work information setting control causes a storage unit (50b) to store the work information (D) having been set, and causes the output unit (43) to display the work information (D) stored in the storage unit (50b) so as to be selectable by the input unit (41). The work information setting control sets the work information (D) selected by the input unit (41) as the work information (D) used for the work of the work machine (10).

Provided is an apparatus for measuring the position and azimuth of a work machine (40), including a specified-point position calculation unit and an azimuth calculation unit. Based on the position of an index mark attached to a work mechanism (44) of the work machine (40) and posture information on the posture of the work mechanism (44), the specified-point position calculation unit calculates a specified-point position, which is the position of a specified point on the work mechanism (44), in a fixed control cycle. Only when a measurement permission condition is satisfied, the azimuth calculation unit calculates the azimuth of the machine body (42) of the work machine (40) based on a previous specified-point position, which is the specified-point position calculated last time by the specified-point position calculation unit, and a current time specified-point position, which is the specified-point position calculated this time. The measurement permission condition includes that current azimuth information corresponding to the current specified-point position is different from previous azimuth information corresponding to the previous specified-point position.
