Method, apparatus and system for presenting spraying operation

A method for presenting a spraying operation, comprising:

• acquiring a spray coefficient of an operating device at an operation location corresponding to a sampling point, wherein the spray coefficient is used for representing an amount of a chemical sprayed from the operating device at the operation location;
• acquiring an element corresponding to the operation location according to the spray coefficient, wherein the element is an element in a presentation interface;
• determining information on a change trend between adjacent elements;
• and
• presenting the operation location, the element corresponding to the operation location, and the information on the change trend.

A method for presenting operation information, comprising:

• acquiring an operation coefficient of an operating device at an operation location corresponding to a sampling point, wherein the operation coefficient is used for representing an amount of operation of the operating device at the operation location;
• acquiring marking information corresponding to the operation location according to the operation coefficient;
• and
• presenting the operation location and the marking information corresponding to the operation location.
