  • the data interval changing unit 170 may interpolate the recording position information 304 included in the work data 300 to generate display position information with a smaller data interval than the recording position information 304. For example, the data interval changing unit 170 interpolates display position information not included in the recording position information 304 based on the recording position information 304 .
  • the data interval changing unit 170 may determine the data interval of the display position information based on the display data interval represented by the display setting data 310 and the recording position information 304 included in the work data 300. good. For example, when the display data interval represented by the display setting data 310 is not the data interval obtained by dividing the data interval of the recording position information 304 by an integer, the data interval changing unit 170 changes the data interval of the recording position information 304 to The data interval divided by the integer is determined as the display data interval.

  • the data interval changing unit 170 generates display position information according to the determined new display data interval.
  • the data interval changing unit 170 also divides the data interval of the recording position information 304 by an integer (for example, the data interval of the recording position information 304 divided by 2, the data interval of the data divided by 3 interval, etc.), a data interval that is smaller than and largest than the display data interval represented in the display setting data 310 may be determined as the new display data interval.
  • the work type determination unit 160 can select any method as long as it can determine the work type of the work performed by the work vehicle 30 .

  • the output unit 180 may output information representing the generated display position information, and may output information representing a display image displayed on the input/output device 210 of the terminal 200, for example. In this case, the output unit 180 generates a display image to be displayed on the input/output device 210 based on the display position information. The generated display image is transmitted from the output unit 180 to the display unit 250 and displayed by the display unit 250 .
