Work map provision server

A work map provision server comprising:

• a memory configured to store first processor-executable code, a plurality of fertilizer application maps, and respective attribute information for each fertilizer application map of the plurality of fertilizer application maps, wherein:
• the respective attribute information for each of the fertilizer application maps includes scheduled work period information indicating a period of time during which a corresponding fertilizer application map is to be used and work identification information indicating work for which the corresponding fertilizer application map is to be used, and
• each fertilizer application map of the plurality of fertilizer maps is composed of second processor-executable code that, when executed by a processor of a work vehicle, controls the work vehicle to apply a target amount of fertilizer to each respective area of a plurality of areas in a farm field;
• and
• a processor in communication with the memory, the processor configured to execute the first processor-executable code to:
• receive a map acquisition request at a receiving time and date, the map acquisition request including map narrowing-down information that includes information specifying work to be performed,
• select, from among the plurality of fertilizer application maps, a fertilizer application map based on scheduled work period information of the fertilizer application map indicating a period of time that includes the receiving time and date of the map acquisition request, and on the work identification information of the fertilizer application map indicating work that includes the work to be performed of the map acquisition request, and
• transmit the fertilizer application map for use by the work vehicle.

• receive a map acquisition request at a receiving time and date, the map acquisition request including map narrowing-down information that consists of vehicle position information indicating a position of a work vehicle and information for work specification to specify the work,
• select one or more fertilizer application maps, from among the plurality of fertilizer application maps, as fertilizer application map candidates, wherein the one or more fertilizer application maps are indicated by farm field location information to be used in a farm field that is within a predetermined distance from the vehicle position indicated by the vehicle position information,
• select a final work map candidate from among the selected fertilizer application map candidates, wherein the final fertilizer application map candidate is indicated by work identification information to be used for work specified by the information for work specification of the map acquisition request and is indicated by scheduled work period information to be used for a period of time that includes the receiving time and date of the map acquisition request;
• and
• transmit the final fertilizer application map candidate for use by the work vehicle.
