  • Patent number: 9958287
    Abstract: Based on map information acquired from a map DB, a viewpoint for viewing a ground surface on a map of a set region at a time of displaying the map is set. Altitude information that indicates an altitude of a landform present in at least a partial region of the set region is stored. In a case where the altitude information is present in the map DB at a position on the map, which is set in response to a position indicated by inputted position information, a sight direction of the viewpoint is changed, and the viewpoint is thereby set at a position higher than the altitude of the landform, which is indicated by altitude information of the position on the map. A display data for displaying, on a display device, a map in a case of viewing the ground surface from the viewpoint set is generated.

  • Publication number: 20140278619
    Abstract: A harvest support method executed by a computer includes determining a day within a harvest grace period of a first cultivation among cultivations of crops as a recommended harvest date of the first cultivation where the day has a minimum interval with a planned harvest date of the first cultivation; and determining a day included in a harvest grace period of a second cultivation among the cultivations of crops as a recommended harvest date of the second cultivation where the day has an interval with the planned harvest date of the first cultivation in which the interval is closest to an interval between the planned harvest date of the first cultivation and a planned harvest date of the second cultivation, wherein the harvest grace periods and planned harvest dates of the first and second cultivations are stored in a storage unit.

  • Publication number: 20140249874
    Abstract: A farm work support method executed by a computer includes calculating a forecast harvest date of a first cultivation of crops based on result values of a weather condition from a start date of the first cultivation to a current day stored in a storage unit, and forecast values of the weather condition after the current day stored in the storage unit, and calculating a forecast harvest date of a second cultivation of crops based on the forecast values after the current day stored in the storage unit; and determining the current day as a start date of the second cultivation if an interval between the forecast harvest date of the first cultivation and the forecast harvest date of the second cultivation has the number of days greater than or equal to a predetermined number of days.
